## What is SIX?

SIX Payment Services has been part of Worldline since 2018 and provides card terminals and processing for retail. The POS system controls the terminal: send the amount, receive the result, print the receipt.

## What we have built

- Card payments on SIX terminals integrated into the branches' POS system.
- Result of the card payment directly in the POS transaction and in the cash close.

## What matters in the integration

- Connection lost in the middle of a payment: clarify the status unambiguously before the customer leaves.
- Bring together the end-of-day close on the terminal and the cash close.
- Make device setup and updates plannable for many branches.

## What we build around it

- POS transaction, payment and receipt as one continuous flow.
- End-of-day close and cash close reconciled automatically.
- Device setup and updates that can be rolled out across many branches.
- Automated tests directly on the terminal, from the build pipeline.
- Monitoring of devices and services in the branches.

## Frequently asked questions

### Can Limeship integrate SIX into our existing system?

Yes. We have already integrated SIX in production, in a platform with online portal, apps and branches in several markets. We connect it to your existing backend, whether .NET, Java or another stack, and take over testing, monitoring and operation if you wish.

### What do we need to get started?

A contract with SIX, access to the test environment and the requirements of your business side. We clarify everything else in a first conversation.
