2. added increment, decrement, restore, transfer commands 3. fixed several small bugs and small code cleaning 4. there is strange behavier in the emulator: for 7BUID is seems that there is must be a feature that cam make work card withouth 2nd anticollision loop. NXP reader authenticates, but cant read card contents. all the rest readers works, BUT.... my 7BUID mifare card dont work AT ALL .... I dont know what i should do )
