CNTLESS_GET_CARD_INFO
This Escape command is used to get information about the contactless card placed in the reader’s field.
Input:
The first byte of the input buffer contains the escape code.
Output:
Byte0
Byte1
Byte2
Contactless card
present (0x01)
Card to Reader communication
baud rate (0xNN - see details in
the next table)
Card Type Info: Upper nibble indicates memory
card, T=CL, or dual mode card; Lower nibble
indicates Type A or Type B card.
(See the Card Type Info table below for values.)
Card to Reader communication baud rate (Byte1) settings:
bit Description
b0 1 = 212 Kbps supported from reader to card
b1 1 = 424 Kbps supported from reader to card
b2 1 = 848 Kbps supported from reader (CLOUD 3700 F only) to card
b3 Always 0
b4 1 = 212 Kbps supported from card to reader
b5 1 = 424 Kbps supported from card to reader
b6 1 = 848 Kbps supported from card to reader (CLOUD 3700 F only)
b7 0 = different baud rates used for the two directions (reader to card versus card to reader)
1 = same baud rate used for both directions (reader to card and card to reader)
Examples:
If 0xNN = 0x77, the card supports all baud rates (namely 106, 212, 424, and 848 Kbps) in both
directions.
If 0xNN = 0xB3, the card supports 106, 212, and 424 Kbps in both directions.
