As one of the most widely used low-frequency RFID core materials, the TK4100 inlay serves as the fundamental component for countless contactless RFID card and tag solutions across global industries. Favored for its stable performance, universal compatibility and cost-effectiveness, it has become a mainstream choice for access control, identification and industrial tracking scenarios worldwide.
The TK4100 inlay is a passive 125KHz contactless RFID inlay built with the classic TK4100 read-only chip. Adopting battery-free induction power supply design, it absorbs electromagnetic energy from RFID readers to complete non-contact identification, featuring low power consumption, zero maintenance and long service life. Different from high-frequency NFC inlays with complex functions, the TK4100 inlay focuses on reliable single identification performance, with a standard reading distance of 3cm to 10cm, perfectly matching most mainstream 125KHz card readers, access control locks and attendance devices on the market.
Structurally optimized for practical application, this RFID inlay integrates a high-precision chip and flexible copper antenna, delivering excellent environmental adaptability. It can resist daily temperature fluctuations, minor friction and extrusion, maintaining stable identification performance in long-term use. Equipped with a 64-bit fixed read-only unique ID code, each TK4100 inlay features exclusive identity information without duplication, effectively avoiding identification confusion and ensuring high security for user management scenarios. In addition, it supports multiple mainstream encoding formats and is fully compatible with EM4100 series protocols, adapting to most traditional and new RFID system equipment.
Thanks to its ultra-thin, lightweight and flexible characteristics, the TK4100 inlay supports diverse packaging and molding processes. It can be easily embedded into PVC smart cards, RFID key fobs, silicone wristbands, animal ear tags and ultra-thin adhesive labels, covering a wide range of application scenarios including residential and office access control, staff attendance, campus identification, hotel room cards, industrial product tracking and animal management. Its simple structure, stable quality and affordable cost make it the preferred basic RFID material for small and medium-sized enterprise procurement and mass customized orders.
