Asked to design new NFC style device with possible for Both Mag+NFC+ NFCProxy capability.
(Design in works)
Testing new code for both offline reset PIN try count values PTC max value exceed (Offline Mode Current)
Code:

update_pin_try_counter(tries):

	#Reset Card Status Update

	if tries > 0x0f:

		return False, 'PTC Attempt MAX

	csu= []

	csu.append(tries)

	csu.append(0x10)

	csu.append(0x00)

	csu.append(0x00)

	tag= 0x91 # Issuer Authentication Data (IAD)

	lc= len(csu) + 1

def generate_ac(type):

	# generate an application Cryptogram

	if type == TC:

		# populate data with CDOL1

		print 

	apdu= GENERATE_AC + [lc,type] + data + [le]

	le= 0x00

Question...
for the decode of the aip data the first byte of AIP is bit masked where as byte 2 is of RFU so for this would be as
for x in AIP_MASK.keys();
if data [0] & x:
print ' ' + AIP_MASK[x}
After this point decode the afl data and print to hex?
