Issuer host connection to the payment schemes have to adhere to payment scheme requirements. This is a pre-requisite before issuers can transition to production.
We at PayHuddle, help you with test plan optimization and host integration testing. We have done this for several issuers across payment schemes.
Orion, the PayHuddle host platform acts as the network simulator, acquirer simulator, card simulator and POS simulator in performing issuer host testing. Issuer testing is carried out using card data from either a simulated card or a physical test card.
