9. EMV L2 Data Output Formats
9.1. Standard Transaction Mode
The following sections describe data outputs that apply in USB-HID mode (as opposed to Keyboard
mode involving Quick Chip; see Quick Chip and M/Chip Fast Transaction Mode
further below for more
details). For addition detail on data output formats for MSR and EMV, see ID TECH document 80000502-
001, ID TECH Encrypted Data Output Formats.pdf, available from

9.2. No Data encryption Key & No TransArmor Certificate:
ErrorResponse Body: 15 04 00
The Response Data – 02 <Len_L><Len_H>15 04 00<LRC><SUM> 03
9.3. TDES/AES mode & Data encryption Key exist:
