Uart Interface Output:

Card Types:

0x02 EM4100

0x01 Mifare 1K

0x03 Mifare 4K

0x10 HID card

0x11 T5567

0x21 ISO14443B

0x22 FELICA

0x30 15693 tag

0x50 CPU card

0x51 sector information

0xFF keyboard data

For example:

02 0A 02 2E 00 B6 D7 B5 F2 03

The first byte 0x02 indicates that the data starts.

The second byte 0x0A, indicates that the entire data length is 10 bytes, including data start and end of data.

The third byte 0x02, indicates that the card type is EM4100.

The fourth byte to the eighth byte (0x2E 0x00 0xB6 0xD7 0xB5) , indicates card number, where the fourth byte 0x2E is the hidden card number.

The ninth byte 0xF2, indicates the BCC check for the second byte to the eighth byte.

The tenth byte 0x03 indicates that the data ends.

Precautions

lFar away from the interference source, strong interference signal may affect the reader.

lThe choice of linear power supply can significantly improve the card reader distance and effect, switching power supply has a certain attenuation on the reader distance, but does not affect working normally and stablely.

lWorking voltage: 3 ~ 5V, remember not to use a higher voltage.

lThe module itself will occur high-frequency signal, the analog circuit may have some interference. Module placement should be a certain distance with the buzzer, the close distance will make the buzzer sounds small and so on.
