We have developed a custom app that utilizes 13.56 mhz RFID cards. The solution worked fine on the Flex 1, but we are trying to migrate to Flex 2 and the new device is not reading our 13.56 cards. It works fine with the NFC chips on credit cards, but it seems like it isn't even reading the 13.56 cards. Has the hardware changed to limit this with the new Flex 2??
