NFC Magnetic Stripe Cards: Combining Contactless and Legacy Card Technology
NFC magnetic stripe cards combine a contactless smart-card interface with a traditional swipe-readable magnetic stripe in one physical card. This hybrid structure allows organizations to operate newer NFC or 13.56 MHz systems while maintaining compatibility with existing magnetic-stripe readers during system migration.
These hybrid smart cards are used in hotel systems, access control, membership programs, loyalty programs, campuses, corporate identification, events and other applications where different readers or credential technologies may operate at the same time.
For professional buyers, however, simply specifying “NFC + magnetic stripe” is not enough. The correct card must be selected according to the NFC chip family, protocol, memory, security requirement, magnetic coercivity, track format, reader compatibility, encoding data, card material and application software.
Wallis manufactures custom NFC PVC cards with magnetic stripes for B2B projects requiring contactless technology, HiCo or LoCo magnetic stripes, custom printing, personalization and encoding.
What Is an NFC Card with a Magnetic Stripe?
An NFC magnetic stripe card contains two different data interfaces inside the same card body:
Contactless interface: an embedded NFC or compatible 13.56 MHz HF chip and antenna communicate with a supported reader.
Magnetic stripe interface: encoded magnetic tracks are read when the card is swiped through a compatible magnetic-stripe reader.
These interfaces can support the same business workflow or completely different functions. For example, the NFC chip might identify a hotel guest at a contactless reader while the magnetic stripe remains available for older door locks. In another project, NFC could open a digital profile while the stripe stores membership or attendance data used by an existing system.
The relationship between both data sets must therefore be defined before production and encoding.
NFC vs. Magnetic Stripe: How the Two Technologies Differ
| Feature | NFC / HF Smart Card | Magnetic Stripe |
| Reading Method | Contactless tap or close-proximity communication | Physical swipe through a magnetic reader |
| Typical Frequency | 13.56 MHz for NFC-compatible HF technologies | Not RF-based |
| Data Technology | Chip memory, protocol and application-dependent data | Magnetically encoded track data |
| Security Capability | Depends strongly on the selected chip and system architecture | Primarily static encoded data; backend controls remain important |
| Typical Use | Access, NFC marketing, membership, transport, hotel, identity and approved payment systems | Legacy access, hotel, loyalty, identification and selected payment environments |
| Hybrid Advantage | One card can interact with both newer contactless equipment and compatible legacy swipe readers. |
How NFC Technology Works Inside a Plastic Card
An NFC or HF smart card normally contains an integrated circuit connected to an antenna embedded inside the card structure. When the card enters the field of a compatible contactless reader, the reader provides the RF energy and communication channel needed for the chip to exchange data.
The actual capabilities depend on the selected chip. A basic NFC tag may store a URL, contact information or identification number, while a more advanced smart-card chip can support authentication, application files, encrypted communication and controlled access to stored data.
Choosing the Right NFC Chip for a Hybrid Card
A common sourcing mistake is specifying only “13.56 MHz NFC.” Frequency alone does not guarantee compatibility. Buyers must identify the required protocol, chip family, memory, security functions, reader firmware and application.
NTAG for Smartphone and Digital Interaction
NTAG-series chips are commonly considered for digital business cards, website links, product information, contact sharing, social profiles and other smartphone-oriented NFC applications. Different chip models provide different memory capacities, so the required NDEF data should be confirmed before chip selection.
MIFARE for Existing Card Systems
MIFARE-family products are widely associated with access, hospitality, campus, transportation and other smart-card systems. The exact chip must match the reader and software already installed in the customer's system.
DESFire for Applications Requiring Advanced Smart-Card Functions
DESFire-family chips may be evaluated for projects that need more advanced authentication, file management and security capabilities. Chip selection should be coordinated with the system integrator because keys, application configuration and reader support are part of the complete system.
Not Every 13.56 MHz Card Works With Every Smartphone
Smartphone compatibility depends on the chip, NFC standard, phone hardware, operating system and application. If smartphone interaction is required, the intended chip should be tested on representative phones before bulk production.
HiCo vs. LoCo Magnetic Stripe: Which Should You Choose?
Magnetic stripes are classified partly by their coercivity, which describes the magnetic field strength required to encode or change the stored information. The correct stripe should match the existing encoder, reader, application and expected card life.
| Comparison | LoCo Magnetic Stripe | HiCo Magnetic Stripe |
| Coercivity | Lower coercivity; approximately 300 Oe is a common project reference | Higher coercivity; approximately 2750, 3000 or 4000 Oe are common project references |
| Rewriting | Requires a lower magnetic field for writing | Requires a stronger magnetic field for writing |
| Accidental Erasure Resistance | Lower | Higher |
| Typical Project Examples | Hotel, temporary issue, loyalty and selected frequently rewritten card systems | Access control, employee ID, long-term membership and repeated-use applications |
| Selection Rule | Confirm coercivity, encoder, reader, track format, service life and existing system before production. |
Why Combine NFC and Magnetic Stripe Functions?
Support for Mixed Reader Infrastructure
Many organizations do not replace every reader at the same time. A hotel chain, campus or enterprise may have newer contactless readers in one location and older magnetic-stripe equipment elsewhere. A hybrid credential can support a staged migration without immediately issuing separate cards.
One Card Can Support Multiple Business Functions
The two technologies do not have to store identical information. A card can be designed so NFC supports one application while the stripe works with another approved legacy system.
Faster Contactless Interaction Where Supported
NFC-enabled readers allow users to present a card without inserting it into a swipe slot. This can improve user flow in suitable access, membership, event, transportation and hospitality environments.
Migration Without Immediate Legacy-System Replacement
For organizations gradually replacing old readers, a dual-technology card can provide a practical transition tool. The long-term migration strategy should still consider when legacy magnetic-stripe systems will eventually be retired.
Security Can Be Upgraded Through the Smart-Card Interface
Advanced contactless smart-card chips can support security features that are not available from a conventional static magnetic stripe alone. However, security should never be described simply as an “NFC feature.” Authentication, encryption and anti-cloning capability depend on the selected chip, key management, reader and backend architecture.

Applications of NFC Magnetic Stripe Cards
Hotel Key Cards
Hotels migrating from magnetic-stripe locks to contactless systems can evaluate hybrid cards when multiple lock technologies remain in operation. The exact chip and stripe must match the installed lock encoders and readers.
Access Control and Employee Cards
Offices, factories and campuses may use a hybrid credential during migration from legacy swipe readers to newer contactless access-control systems. Chip type, credential format and encryption requirements must match the access-control platform.
Membership and Loyalty Cards
Gyms, clubs, retailers and membership organizations can combine contactless identification or digital interaction with compatibility for existing stripe-based membership infrastructure.
Campus and Student Cards
Universities and schools may operate several credential systems simultaneously, including access, library, attendance, vending and identification. Hybrid cards can help integrate or migrate selected functions when the underlying systems support them.
Events and Visitor Credentials
Event organizers can use contactless chips for check-in, digital interaction or access while maintaining stripe compatibility with existing equipment where required.
Transportation and Closed-Loop Systems
Selected transportation or stored-value systems may use multi-technology cards, but the chip, data format and transaction system must be specified by the operator. Generic NFC cards should not be assumed to work in an existing transport infrastructure.
Approved Payment Card Projects
Contactless payment cards can combine contactless chip technology with additional interfaces, including magnetic-stripe functionality in systems where it remains required. However, a generic NFC PVC card is not automatically a bank card, credit card or EMV payment card.
Open-loop payment projects require the appropriate secure payment chip, application, personalization environment, key management, certification, terminal compatibility and authorization from the relevant issuer, payment network or system operator.
NFC Card vs. RFID Card vs. Dual-Interface Card
These terms are often used interchangeably in commercial discussions, but they do not always mean the same thing.
| Term | Meaning in Card Projects |
| NFC Card | Usually refers to a compatible 13.56 MHz contactless card designed to communicate using NFC-related technology. |
| RFID Card | A broader category that can include LF, HF and other radio-frequency credential technologies. |
| NFC + Magnetic Stripe Card | A multi-technology card containing a contactless NFC/HF interface plus a magnetic stripe. |
| Dual-Interface Payment Card | Typically refers to a secure chip card supporting contact and contactless chip interfaces within an approved payment system; this is not synonymous with a generic NFC magnetic-stripe card. |
How to Specify Magnetic Stripe Encoding
“Add a magnetic stripe” is not a production-ready specification. Buyers should confirm exactly how the stripe will be manufactured and encoded.
HiCo or LoCo: specify the required coercivity.
Stripe width: confirm the required physical width.
Stripe position: provide its distance from the finished card edge.
Track configuration: identify which tracks will be encoded.
Data format: supply the exact encoding specification.
Reader and encoder: identify existing equipment where possible.
Card orientation: clearly define front, back and swipe direction.
How NFC and Magnetic-Stripe Data Can Work Together
Same Credential Across Both Interfaces
A project can map both technologies to the same user or account record in the backend system. The exact data written to each interface does not necessarily need to be identical, but the system can associate them with the same credential holder.
Different Functions on the Same Card
The NFC chip and magnetic stripe can also operate independently. For example, one could support room access while the other supports a legacy loyalty or attendance system.
Data Mapping Must Be Defined Before Encoding
For bulk personalization, the customer and card manufacturer should agree on which database field is written to the chip, which information is encoded on each magnetic track and which values are printed on the visible card.
Custom Printing and Personalization Options
Hybrid card projects can combine electronic functions with customized visual branding and individual personalization.
Company logo and full-color artwork
Cardholder name
Membership or employee number
Serial number
QR code
Barcode
Printed NFC UID where required
Expiry date
Signature panel
Holographic or anti-counterfeit visual elements
Glossy or matte finish
How to Choose an NFC Magnetic Stripe Card
1. Start With the Existing Reader
Identify the contactless reader, magnetic-stripe reader, encoder and management software already installed. Selecting a card before identifying the reader can result in incompatible credentials.
2. Identify the NFC or Smart-Card Chip
Specify the exact chip if your system already requires one. If not, provide the application, reader and required security level so a suitable chip can be discussed.
3. Choose HiCo or LoCo
Match magnetic coercivity with the existing encoder, expected rewrite frequency, card lifetime and exposure environment rather than selecting solely on price.
4. Define the Data on Each Interface
Determine which data will be stored or encoded on the NFC chip, magnetic stripe, printed card and backend database.
5. Confirm Card Material and Construction
PVC is common for printed smart cards, but the final material should be selected according to card life, printing, lamination, environmental requirements and personalization process.
6. Test a Functional Sample
Test both the NFC interface and magnetic stripe using the actual readers, encoders, smartphones or terminals that will be used in production.
7. Approve the Encoding Specification
Before mass personalization, approve the track format, NFC data structure, keys where applicable, variable-data file and validation procedure.

Destination: delivery country or port for commercial quotation.
The Future of NFC and Magnetic Stripe Hybrid Cards
Contactless smart-card infrastructure continues to expand, particularly in access control, hospitality, transportation, identification and payment systems. At the same time, many organizations still operate installed magnetic-stripe readers that cannot be replaced immediately.
Hybrid cards are therefore particularly useful as a migration technology: they allow organizations to introduce newer contactless credentials while retaining compatibility with selected legacy equipment during a controlled upgrade.
In open-loop bank-card payments, however, the long-term direction is increasingly toward chip and contactless technology rather than dependence on magnetic stripes. For this reason, organizations developing a new card program should distinguish between temporary legacy compatibility and the technology architecture they expect to use over the full life of the system.

Frequently Asked Questions About NFC Magnetic Stripe Cards
What is an NFC magnetic stripe card?
It is a multi-technology card combining an embedded NFC or compatible HF smart-card chip with a conventional magnetic stripe. The contactless and magnetic interfaces can support the same credential or different applications.
Can one card work with both NFC readers and magnetic-stripe readers?
Yes, when the selected NFC chip is compatible with the contactless reader and the magnetic stripe coercivity, position, track format and encoding match the swipe reader. Both interfaces should be tested before mass production.
Is every 13.56 MHz card an NFC card?
No. 13.56 MHz describes the operating frequency used by many HF technologies, but smartphone NFC compatibility also depends on the chip family, protocol and supported standards.
What is the difference between HiCo and LoCo magnetic stripes?
LoCo stripes use lower coercivity and require a lower magnetic field to encode, while HiCo stripes require stronger encoding and generally offer greater resistance to accidental magnetic erasure. The correct choice must match the existing encoder and application.
Can NFC magnetic stripe cards work with smartphones?
They can when a suitable NFC-compatible chip and supported data format are selected. Not every HF smart-card chip is readable by every smartphone, so representative devices should be tested.
Can NFC magnetic stripe cards be used for payment?
Only when the complete payment system supports it. A generic NFC PVC card is not automatically an EMV payment card. Open-loop payment projects require the appropriate secure payment chip, approved applications, certified infrastructure, controlled personalization and authorization from the relevant issuer or payment system.
Can the NFC chip and magnetic stripe store different information?
Yes. They can store or reference different data and support separate applications. The required relationship between the NFC, magnetic-stripe, printed and backend data should be defined before encoding.
Which NFC chip should I choose?
Chip selection depends on the reader, application, memory, smartphone compatibility, protocol and security requirement. NTAG may suit simple smartphone interactions, while MIFARE or DESFire may be required by more specialized access, hotel, campus or smart-card systems.
Can Wallis encode both NFC data and magnetic-stripe data?
Encoding can be discussed according to an approved project specification. Buyers should provide the NFC data format, magnetic track requirements, variable-data file and any relevant system restrictions before production.
Can every card have different personalized information?
Yes. Projects can include variable names, IDs, serial numbers, QR codes, barcodes and other individual information. The personalization file should contain one controlled record for each card.
Should I send my reader model before ordering?
Yes. Providing the contactless reader, magnetic-stripe reader and encoder models significantly reduces compatibility risk and allows the supplier to evaluate the project against the real operating environment.
Should I test a sample before placing a bulk order?
Yes. Test NFC reading, magnetic-stripe reading, encoded data, printing, variable information and any required smartphone or system interaction before approving mass production.
Build the Hybrid Card Around Your Existing System
The most reliable way to source an NFC magnetic stripe card is to begin with the system rather than the card itself. Identify the reader, NFC chip, magnetic-stripe format, encoding rules, software, cardholder data and required workflow, and then design the physical credential around those requirements.
For hotels, access-control providers, membership programs, campuses, distributors and system integrators, this approach helps reduce compatibility problems and makes it easier to migrate from legacy swipe technology toward contactless smart-card infrastructure.
Send Wallis your chip requirement, reader model, HiCo or LoCo specification, stripe position, printing artwork, encoding requirements and expected quantity to discuss samples and custom production.
