Why Keynius + Worldline matters
Keynius and Worldline support paid smart locker deployments where visitors or customers need to pay quickly and receive secure locker access without staffed handling. Worldline's Terminal API documentation supports communication between business systems and payment terminals, while Keynius manages locker assignment, access, timing, usage logs, and support processes. This combination is useful in venues, stations, hospitals, retail environments, and leisure sites that want to reduce cash handling, improve throughput, and keep payment evidence connected to locker events.
