ZKTeco TK-4100D Thin Type 125kHz Proximity RFID Card

The ZKTeco TK-4100D Thin Type 125kHz Proximity RFID Card is a reliable and widely used RFID card designed for access control systems, attendance devices, and security identification applications. It operates on 125 kHz proximity technology, allowing users to gain access by simply placing the card near a compatible RFID reader. Because of its simple and efficient design, this card is commonly used in offices, schools, apartments, and industrial facilities for secure entry management.

The card features a thin and lightweight PVC design that makes it easy to carry in wallets, card holders, or ID lanyards. It uses the TK4100 chip, which contains a unique pre-programmed identification number. When the card is presented to an RFID reader, the reader detects this unique ID and verifies it against the system database to allow or deny access. Since the card is read-only, it cannot be reprogrammed, which helps maintain consistent and reliable identification.

The ZKTeco TK-4100D proximity card is compatible with most 125 kHz RFID readers and access control devices, making it an ideal accessory for biometric attendance machines, door access control terminals, and gate entry systems. Its durable construction ensures long-term performance and resistance to everyday wear, dust, and moisture.
