RFID Reader Writer SRK 502|13.56MHZ| DC 3.0-5.5 V|LED indicator

RFID is frequency Identification. An RFID reader is employed to read RFID tags (which contain certain unique data stored during a chip). An RFID reader and an RFID tag, both have a coil surrounding them. This contactless 3V-5V RFID YHY502CG Reader Writer UART Interface module is meant for a simple reader adaptation to a number to use this device for test and application purpose. there's need just one command to end one action, like read or write card data. It needs no request or selection. The module will roll in the hay for you automatically. What you would like is simply send one command to the module. Then it'll remit what you would like. Anything is simply so simple then easy. Also, if there's any card enter the rf field, the red led on the module will light and therefore the SIG pin will change from “1” to “0” to point the event.

This HY502 series of RFID reader/writer modules are supported non-contact card reader ASCI chip compatible with ISO14443 standard. It uses 600nm CMOS EEPROM technology, supports ISO14443 A protocol, and also supports the MIFARE standard encryption algorithm. The chipset integrates analogue modulation and demodulation circuits only require minimal peripheral circuits to function. The module supports UART interface. The digital circuits have dual working voltages mode, TTL and CMOS. The HY502 module is targeting water, electricity, gas meters, vending machines, access control, elevators, drinking fountains, telephone billing system or other identification card reader system applications.
