HZ55/HZ57 series 125KHZ RF ID card, non-contact device is read-Bian with advanced RF and embedded microcontroller circuit design combined with efficient decoding algorithms, to complete the 64bits Read-Only uem4100-style ID card compatible receiver, with receiver small current of high sensitivity, job ﹑ ﹑ single DC power supply low-cost high-performance characteristics. HZ55/HZ57 device for read access time and attendance, charges ﹑ ﹑ security and other RFID applications.

Instructions for use:

Read-only device is powered, the lights turn on, and then always a red light and buzzer sound Ming Chang. Cards close, flashing red light to green light into red light a little longer. Card reader and if the ID card is still RF sensing devices will not read the region re-read the card number. the same ID card reader and quickly left the RF sensitive area when they enter the area, only the reader will not read the ID card number. different radio frequency ID cards to enter the sensor area, respectively, range, continuous read-reader devices.
