I think you'll find OneCard uses the mag strip, not a bar code. The barcode on current cards is used for AA Smartfuel and the mag strip for Countdown OneCard (AA Smartfuel may be encoded on the mag strip also, but they only scan the barcode). Two different numbers (SmartFuel and OneCard), two different systems. You might be able to add the AA Smartfuel barcode though. Although, I'm not sure either system will work through the Android Pay mechanism. Will look into it I guess!
