      EM-18 RFID readeris one of the commonly usedRFIDreader to read
      \n125KHz tags. It features low power consumption, small form factor
      \nand easy to use. It provides both UART and Wiegand26 output
      \nformats. It can be directly interfaced with microcontrollers
      \nusing UART and with PC using an RS232 converter.<\/p>\n

      Specifications<\/p>\n

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

      RS232 interface format:<\/p>\n

      10 ASCII DATA (card no.)+ 2 ASCII DATA (XOR result)<\/p>\n

      E.g. Card number is 4500C5D1E9B8 read from reader then the card
      \nnumber on card will be as below.<\/p>\n

      45 – Preamble<\/p>\n

      00C5D1E9 value in Hex = 12964329. \/ B8 is XOR value for (45 XOR
      \n00 XOR C5 XOR D1 XOR E9)<\/p>\n

      1. Data baud 9600 bps
      \n2. Data bit 8 bits
      \n3. Parity check: None
