Data Format
| STX | Length | CardType | SNR [0..N] | BCC | ETX |
The following table describes the packet fields
| Field | Length | Description |
| STX | 1 | 0x02, the starting of a data packet. |
| Length | 1 | Length of the data bytes in the packet (except STX). |
| CardType | 1 | 0x01: MF Classic; 0x02: EM4100 |
| SNR [0..N] | 5 | SNR[0]:batch number, SNR[1..4]:serial numbers |
| BCC | 1 | BCC = Length xor CardType xor SNR[0..N] |
| STX | 1 | 0x03, the ending of a data packet. |
Example: 02 0A 02 06 00 8E 6D 5D B0 03
STX: 02
Length: 0A, 9 bytes
CardType: 02, EM
SNR: 06 00 8E 6D 5D, 06 = batch number, 00 8E 6D 5D = 0009334109 (DEC)
BCC: B0, B0 = 0A xor 02 xor 06 xor 00 xor 8E xor 6D xor 5D
