Not every shop has room for a full-size self-checkout lane. A mini self-checkout with a 15 or 15.6-inch screen fits on a counter or small stand, making self-service practical for convenience stores, forecourts, pharmacies, cafés and specialist retailers.

Frequently asked questions
What is a mini self-checkout?
A compact self-checkout, usually with a 15 to 17-inch screen, that sits on a counter or small stand rather than a full-size lane.
Can a mini self-checkout weigh produce?
Some models offer optional scales. For heavy grocery use, a full-size self-checkout with a scanner-scale is usually better.
