Previously, a card could be scanned twice in a row and it's state would be kept in memory so the card would be scanned again as soon as a credit ended.
Added debug strings
Merged logic to read cards from a local file from CrazyRedMachine's redboard repository.
Added the ability to select a card from the files by pressing and holding a number on the keypad.
Bumped version
This currently only really works well with felica lite cards (amusement IC).
Older cards or different types (Mifare) should work too but their id won't be correct.
Updated readme
Edited build64.bat
