3pcs 125KHz Proximity RFID Card

This is an RFID card with an operating frequency of 125KHz and a data transfer speed of 106 kbits/s. These RFID (radio frequency identification) cards are used in applications where tracking or identifying personnel is important or where access control is required. It is basically used for contactless transmission of data and supplies energy with no battery need. Its operating distance is 100mm depending on antenna geometry.

It is featured with the data integrity of 16 BIT CRM, parity, bit coding bit counting which allows anti-collision. The device is typically used in ticketing transactions: <100ms including backup management.
