Adafruit RFID RFID/NFC S50 Card Reader - PS/2 Interface

For projects utilizing RFID 13.56MHz tags or cards, this compact RFID reader offers an efficient solution. Encased in durable plastic, it features an LED and buzzer that activate upon card reading, transmitting the 4-byte card ID through a PS/2 cable as if typed by a keyboard.

This reader exclusively reads the permanent 4-byte ID on each 13.56 MHz tag, making it ideal for identifying cards but not for data storage. Compatible with most microcontrollers, it seamlessly integrates with existing PS/2 keyboard examples. Arduino users will find success using PJRC's PS2_Keyboard library, specifically the 'simple text' example on an Uno with digital pins 2 and 3. A PS/2 adapter cable simplifies wiring connections.

Experience the ease of reading RFID/NFC tags by bringing them close to the reader and observing the ID number 'typed' in decimal format in the serial monitor. Note that compatibility is primarily with classic RFID/NFC S50 tags. For reading and writing to EEPROM or using different 13.56 MHz tags, consider our PN532-based options.
