Get the Rewards app.

The till for your shop: scan your customers' cards, give stamps and rewards, and see who comes back. Managers sign in with their email, staff with the shop's link and their PIN.

The iPhone app is on its way to the App Store and isn't there yet.

Until then, the till works in any browser: open the till.

The app is free to download. Ivamelt Rewards is £19 a month per shop after 14 days free: see pricing.
