2>.Card Type:
0x02  EM4100
0x01  MIFARE 1K
0x03  MIFARE 4K
0x10  HID Card
0x11  T5567
0x20  2nd Card

0x22  FELICA
0x30  15693 Label
0x50  CPU Card
0x51  Sector Information
0xFF Keyboard Data

For example: the data received by serial port tool is 02 0A 02 2E 00 B6 D7 B5 F2 03, then
    The first byte 0x02 means data start
    The second byte 0x0A means the whole data length is 10 bytes, which includes data start and data end
    The third byte 0x02 means the card type is EM4100
    The fourth to eighth byte (0x2E 0x00 0xB6 0xD7 0xB5) means the read card number, and the fourth byte 0x2E is hidden card number
    The ninth byte 0xF2 means BCC check of second byte to eighth byte
    The tenth byte 0x03 means data end

1. Keep away from interference source, and strong interference signal may affect card reading.
2. Select linearity power can improve the card reading distance and effect; switch power may attenuate the distance but will not influence normal operation.
3. The module can operate normally in the range of 3-5V, please do not use higher voltage.
4. This module has high frequency signal, so it may cause some interference to the analog circuit. Uses should place the module a little far away from the buzzer; if the distance is too close, the sound of the buzzer will be low.
