Clamshell Card Proximity Card RFID Employee Badge

What is Clamshell Card?

The clamshell card, mainly made of a mixture of ABS or PVC materials with a 3*14mm ID hole punched on the top of it, is a kind of proximity badge, and a 125KHz low frequency RFID chip(such as EM4100, T5577, EM4305, etc.) is embedded in it. 

Chip introduction
  • EM4100, a read only chip with a fixed card number, usually outputs data in Wiegand 26 bits format.
  • Both EM4305 and T5577 are both writable chips, which can customize continuous card numbers.
  • The difference is that the card number of the TK4100 chip is random, and the card number of the EM4305 and T5577 chips is determined by ourselves.

Product Applications

Each chip embedded in it has a unique ID number, the ID number can be printed on the lower right corner or even on the bevel of the card, therefore, these cards can be used for the identity confirmation, and they can also be called the RFID ID cards and RFID employee badges.

The employee can use it as a identification card which can open the office doors or a key card with the employee identity certification printed on it, because the single employee information printed or written on it and the access control function have already been combined into this kind of prox card; or use it for the attendance punch. So useful, isn’t it?
