NEO2 Main Transaction Commands
The methods below are provided as a reference to the main commands needed to execute a contact or contactless
EMV transaction, or collect MSR information from a swipe or tap.
4.1 EMV Methods
Start EMV Transaction
emv_startTransaction:amtOther:type:timeout:tags:forceOnline:fallback: (IDT_NEO2)

emv_authenticateTransaction: (IDT_NEO2)
For contact EMV only. By default, auto-authenticate is ON and this step does not need to be performed. If
auto-authenticate is OFF (emv_disableAutoAuthenticateTransaction: (IDT_NEO2)), when the results come back
as EMV_RESULT_CODE.EMV_RESULT_CODE_AUTHENTICATE_TRANSACTION, this method must be called
to continue the EMV transaction.
Complete Online EMV Transaction
emv_completeOnlineEMVTransaction:hostResponseTags: (IDT_NEO2)
For contact EMV only. After receiving a host response, pass host tags (minimum 8A Authorization Response Code)
as a TLV stream through the tags parameter. EMV tags can be parsed returned pointer.
If there was a communication error with host, you must still finish the EMV transaction by passing "FALSE" for
isSuccess, and nil for tags.
