T=Track: 00 = JIS

01 = ISO 1 (ISO Track 1)
10 = ISO 2 (ISO Track 2)
11 = ISO 3 (ISO Track 3)

E=Errorcode: 00 = no error

01 = no Startsentinel detected
10 = Parity-Error
11 = Checksum Error

Example with ISO-Card: Track 1 = ‘1’,Track 2 = ‘2’ Track 3 = ‘3’:

1. Without initialization

after card swipe

02h, 90h, 25h, 31h, 3Fh, 2Bh, A0h, 3Bh, 32h, 3Fh, 36h, B0h, 3Bh, 33h, 3Fh, 37h; F0h

equal ^B É % 1 ? + á ; 2 ? 6 B0h ; 3 ? 7 F0h

2. Initialization: 01h 03h 04h

Response: 06h

after card swipe you will not automatically receive data.

After a Request (02h) you will receive the data

02h, 90h, 05h, 11h, 1Fh, 0Bh, A0h, 0Bh, 02h, 0Fh, 06h, F0h

3. Initialization: 01h 89h 04h

Response: 06h

after a card swipe with checksum error:

02h, 93h, F0h

For testing you can use a terminal program.
