See the price before you pay.
Scan what you pick up. Your phone shows the shop's approved price and a running total, so the till holds no surprises.
- Scan the sign at the shop door. It opens that shop on your phone. No app, no account.
- Scan each item you pick up. You see the shop's price and your running total.
- Pay on your phone. Show your receipt at the exit and staff check your basket.
Cannot find the sign? Ask the shop's staff for it; each shop has its own.
