Beyond Cards and Terminals: Considerations for Testing Host-to-Host EMV Processing

As a Switch network, Gateway, or Interchange, your primary challenge is EMV message mapping and validation.

Your organization will likely need to develop tests that address needs such as:

Testing your validation of the EMV message
- Testing your ability to recognize valid (and invalid) data in the EMV message contents
- Testing your ability to recognize properly (and improperly) formatted EMV messages
Testing your ability to correctly map the EMV tags or EMV tokens before you forward the transaction
Ensuring you are examining the correct EMV tags or EMV tokens when you receive a response message
Testing your fee processing
Testing any required information-handling for card or account management
Testing switch availability, and testing to ensure your ability to process a higher volume of online transactions
