EM-18 RFID reader is one of the commonly used RFID reader to read 125KHz tags. It features low cost, low power consumption, small form factor and easy to use. It provides both UART and Wiegand26 output formats. It can be directly interfaced with microcontrollers using UART and with PC using an RS232 converter.



  • Voltage: 5VDC
  • Current: <50mA
  • Operating Frequency: 125Khz
  • Read Distance: 10cm
  • Size: 32mm(length) * 32mm(width) * 8mm(height)


RS232 interface format: 

10 ASCII DATA (card no.)+ 2 ASCII DATA (XOR result)

E.g. Card number is 4500C5D1E9B8 read from reader then the card number on card will be as below.

45 - Preamble 

00C5D1E9 value in Hex = 12964329. / B8 is XOR value for (45 XOR 00 XOR C5 XOR D1 XOR E9)

Hence number on the card is 0012964329.
1. Data baud rate: 9600 bps
2. Data bit 8 bits
3. Parity check: None
4. Stop bit
