Reading All Emv Tags - Magtek DynaPro Go Programmer's Manual

4 - Command Set

4.5.4.1 Reading All EMV Tags

To read all EMV tags stored on the device, the host should send the following command:
Table 4-77 - Usage Table for Command 0xA1 (Set form to Read All Tags)
Bit 7
Byte 0 0xA1
Specifies which EMV or Contactless tag group to read:
00 = EMV/Contactless
Terminal tag group
10 = EMV/Contactless
Byte 1
Application tag group
11 = Contactless Dynamic
Reader Limits (DRL) tag
group (payWave Only)
Byte 2 0x0F=Read all EMV terminal or payment brand tags
Database Selector:
0x00 = Contact L2 EMV Tags
0x01 = PayPass/MCL - MasterCard (MasterCard PayPass Support Only, MasterCard
Byte 3 MCL 3.1.x Support Only)
0x02 = payWave - VISA (payWave Support Only)
0x03 = Expresspay - AMEX (Expresspay Support Only)
0x04 = D-PAS (D-PAS Support Only)
Response Type:
0x00 = Single ACK response
Byte 4
0x01 = Quick Initial ACK response, followed by an asynchronous delayed response after
the command completes.
Bytes 5..8 Reserved
The Response Type parameter allows the host to specify how it prefers the device to compose its
response. MagTek recommends using Quick Initial ACK response, unless the host software needs to
use Single ACK response for backward compatibility reasons. Quick Initial ACK response is specifically
designed to help avoid connection timeout problems the developer can not control; in some cases, the
device needs more time to compile the full response than the host software's connection library or
operating system allows before automatically timing out the request.
If an error occurs, the device terminates the command and reports the error in ACKSTS of Command
0x01 - Response ACK. For a full list of error codes, see Command 0x01 - Response ACK.

group to read. Note that DRL applies only to Visa
payWave.
