The client needed a middleware solution that would reliably connect HioPosCloud with Switchio Pay terminals via the GSA API. From a business perspective, the key requirements were stable payment acceptance, correct handling of refunds and batch closings, and resilience to network or terminal failures. For end users, payments had to feel instant and seamless, with clear outcomes and minimal errors at checkout.
WislaCode delivered an Android middleware application that acts as a transaction bridge between the POS system and payment terminals. It captures POS actions, translates them into GSA-compliant requests, manages transaction states, and guarantees that results are accurately returned to the POS – even if connectivity is unstable or a transaction needs to be retried or reversed.
Result
A reliable payment middleware that improves checkout stability, reduces transaction errors, and ensures a smooth payment experience for both merchants and customers.
