Product Specifications

Key Features of Wallis RFID Key Fobs

Compact Keychain Design

The small format makes the RFID key fob easy to carry with keys, bags, employee badges or other everyday items.

It can be supplied with a metal key ring, rope or other attachment according to the final design.

Custom RFID Chip Options

Wallis can work with different RFID chip requirements based on the customer's reader system.

Chip selection should be determined according to:

• Frequency

• Reader compatibility

• Memory requirements

• Communication protocol

• Security requirements

• Required application

This avoids selecting a chip simply based on frequency without considering system compatibility.

Custom Logo and Branding

The key fob surface can be customized for brand identification.

Available options may include:

• Company logo

• Product name

• Serial number

• UID

• QR code

• Graphic design

• Custom colors

Printing and finishing methods can be selected according to the material and design.

Durable Construction

Depending on the selected material and construction, RFID key fobs can provide resistance to everyday handling, moisture and surface wear.

ABS and PVC constructions are suitable for many general-purpose RFID key fob applications.

Passive and Battery-Free

The RFID key fob is a passive device and does not require a built-in battery for normal RFID communication.

This allows a compact design while reducing the need for battery replacement.
