PVC wide rectangular RFID keyfob also available with offset printing and transparent resin ATA5577 RFID chip read and write LF 125 KHz ISO 11784 ISO 11785.
The ATA5577 is a contactless read/write identification IC (IDIC®) for applications in
the 125-kHz or 134-kHz frequency band. A single coil connected to the chip serves as
the IC’s power supply and bi-directional communication interface. The antenna and
chip together form a transponder or tag.
The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written
block-wise from a base station (reader)
