pyNFCReader
A little python client to use as a low level contactless smart card reader the Hydra NFC v1 & v2, developed by Benjamin Vernoux:
The communication uses the BBIO reader mode.
Status
-
It works with :
- ISO 14443 A & ISO 15693 card.
- ISO 14443 B only for hydra NFC v2
-
The PCD frame size is currently limited to 16 bytes.
Help
Example
The file pynfcreader/examples/reader_hydranfc_iso14443_a.py contains an example. You can customize :
- the port com and baudrate
- the debug mode.
It enables :
- to select a Master Card card
- to read the first 0x19 response bytes
- to send the Get Processing Options and get the response
Here's a log (where I've changed the UID and the historical bytes of the card :) )
