One Integration Point. Everything Connected.

Services
If a service goes down, the sale still completes. Reconciliation catches up in the background. The queue never stops.
Product Modules
Four modules. One connection.
Add capabilities without re-certifying the register.

Services & Parcels
Every carrier, every service, one screen.
DHL, DPD, UPS, Swisscom, 7Days — five carriers, one workflow. Add mobile top-ups (Salt, Sunrise, Lycamobile), prepaid cards (Paysafe, Cornercard), lottery (Swisslos), and bill payments. Protocol differences disappear behind a single interface. Customers come in for a parcel. They walk out with a full basket.

A message in. A response out.
The ECR opens ePOS in a browser frame, sends one request, and gets one response. Four steps. Every module.
Open
Load ePOS in an embedded browser frame. Device authentication is automatic.
Request
Send one message — CreatePurchaseRequest or equivalent. The UI adapts to the transaction type.
Process
Smarts handles supplier routing, validation, and reconciliation. The ECR waits.
Confirm
Response returned. Vouchers print. SAP reconciliation runs in the background.
