If receiver data is 02 0A 02 2E 00 B6 D7 B5 F2 03.It is means:
1>.The first byte 0x02 is data start flag.
2>.The second byte 0x0A is total length of data.It include start and end byte.
3>.The third byte 0x02 is means the type of card is EM4100.
4>.The 4th to 8th bytes(0x2E 0x00 0xB6 0xD7 0xB5) is card number.The 4th byte 0x2E is a hidden card number.
5>.The 9th byte 0xF2 is XOR Check byte.
6>.The 10th byte is data end flag.
2>.Access control
3>.Industrial control
1>.It just need three wires.
2>.Module just can send data.
3>.User need write code according to UART Protocol Introduction as shown.
4>.Please stay away from interference sources.
