Product Description

TK4100 RFID card is compatible with EM format card, such as EM4100 card and EM4102 card. TK4100 chip data modulating and transmission is coded by Manchester modulation format. Due to the small volume of TK4100 chip and antenna, it is easier to embed in a small and thin tag or ISO card. It is widely using as ID card, information tag, goods tag, package , animal tag , school cards and metal tag ect. Only those who can use the serial number to identify the main object attributes can use it.

TK4100 proximity card is a great solution for access control and time attendance systems, which do not require very high security level.
