125KHz 13.56MHz RFID Inlay PVC Prelam Inlay Sheet for Card

In the fast-paced world of card manufacturing, 125KHz and 13.56MHz RFID Inlay PVC Prelam Inlay Sheets are essential materials that bridge technology with physical security. These sheets serve as the core layer in contactless cards, embedding microchips and antennas for smooth, wireless communication. Whether for access control, payments, or membership systems, the demand for high-quality prelam inlays continues to rise as industries shift toward faster, safer identification methods.

A PVC prelam inlay sheet is essentially a ready-to-laminate structure, containing the RFID chip and antenna embedded between PVC layers. Card manufacturers then print and laminate these sheets into finished cards. This makes them an indispensable component in modern card production.

Understanding RFID Frequencies: 125KHz vs 13.56MHz

Choosing between 125KHz (Low Frequency) and 13.56MHz (High Frequency) is one of the most important decisions in RFID card production.

Low Frequency (125KHz) Overview

• Typical Applications: Access control, time attendance systems, animal tracking.

• Advantages: Stable performance near metal surfaces or liquids, low interference, cost-effective.

• Limitations: Shorter read range (up to 10 cm), lower data transfer rate.

High Frequency (13.56MHz) Overview

• Typical Applications: Contactless payment, public transportation, smart cards.

• Advantages: Higher data transfer speed, better encryption, supports multiple applications.

• Limitations: More sensitive to interference, slightly higher cost.

PVC Prelam Inlay Sheet Composition

A PVC prelam inlay sheet is carefully engineered to balance durability, compatibility, and high-frequency performance.

PVC Core Material

High-grade PVC sheets form the core layer of the inlay. This material offers flexibility, print-friendliness, and resistance to bending and environmental stress.

Antenna and Chip Integration

• Antenna: Usually made from copper, aluminum, or silver conductive ink, designed to match the card’s frequency.

• Chip: The brain of the card, programmed to store and process data securely.

Overlay Lamination

Protective overlays seal the inlay, shielding the chip and antenna from physical wear and moisture.
