## Bytes

### APDU Commands

- SELECT = 00 a4 04 00 07 d2 76 00 00 85 01 00 00
- VERSION = 90 60 00 00 00
- CONTINUE = 90 AF 00 00 00

### APDU Responses
APDU responses will first contain the data followed by two status bytes.

- FRAME_CONTINUE = 91 AF
- OPERATION_OK = 91 00
- OK = 90 00
- INIT = ??
- VERSION 1 = 04 01 01 01 00 1a 05
- VERSION 2 = 04 01 01 01 03 1a 05
- VERSIOn 3 = 04 91 3a 29 93 26 80 00 00 00 00 00 39 08
