Link your till
Your till sends the amount. The card machine does the rest.
No typing the amount twice. Your till or EPOS sends a payment request, the card machine shows it, and the result goes straight back to the till.
- Over your shop's network
- Through the cloud

Pricing
No price list. A quote made for your business.
A busy café and a mobile hairdresser shouldn't pay the same way. We look at how you trade and email you a personal quote.
What we look at
- How much you take by card each month
- Your average sale
- How many card machines you need
- Whether you want to link your till
How much does it cost?
We don't publish a price list. What card payments cost depends on how your business trades: how much you take by card, your average sale and how many card machines you need.
