The main objective for SIHOT.PAYENGINE is to shield implementation details/complexity for the clients (consumer) that consumes a service from the engine.

Additionally on this SIHOT.PAYENGINE shields any credit card data from the consumer's (SIHOT.PMS, SIHOT.WEB etc.) environment and therefore helps with the PCI DSS requirements of these environments.

To do this SIHOT.PAYENGINE acts as a middleware in front of the payment providers and can be seen as an interface for the clients.


To ensure no credit cards are hitting the PMS environment SIHOT.PAYENGINE is capable to act as a PCI Proxy. This proxy extracts the Credit card information tokenize the data and forwards the rest of the message to a given endpoint. Currently the protocols for OTA and INTR messages are supported, more scheduled.
