There's an app for Android that reads MIFARE 13.56MHz transit cards:
The author would like to see eventually emulating such cards:
I would definitely be interested in a board if it was proven it could
read or emulate MIFARE transit tags.
4 wire installation @
easy enough for someone like me to solder :)
