NOTE ON INTERFACE SELECTION: For the NEO2, tag DFEF37 is used to determine which interfaces to use for
the transaction:
• 01 = MSR Only
• 02 = CTLS Only
• 03 = MSR + CTLS
• 04 = EMV Only
• 05 = EMV + MSR
• 06 = EMV + CTLS
• 07 = EMV + MSR + CLTS. This API method will automatically send DFEF37 with a value of 07 if this tag is
not provided.
USE tag DFEF3C for fallback support and timeout waiting for insertion byte 1: = fallback support 01 = YES,
00 = NO byte 2-3 = timeout in BCD. Example 60 seconds is 0060
13.7.2.39 - (RETURN_CODE) emv_authenticateTransaction: (NSData ∗) tags
