Even with good software, checkout is slow without the right hardware. This article covers the two essentials for a shop: the barcode scanner and the receipt printer.
Barcode scanner
A scanner finds an item in a second. The cashier doesn’t have to search for the name or type in the price.
What types are there?
- Wired USB scanner — the simplest and cheapest. Plug it in and it works. The best choice for small and medium shops.
- Wireless scanner — handy away from the till, for example when counting stock in the storeroom.
- Countertop scanner — items are passed in front of it; fast for busy shops.
Your phone can be a scanner too
Some software lets you use the phone’s camera as a scanner, so you can start without buying a separate device.
What about items without barcodes?
For bread, fruit or items sold by weight, use search by name or your own internal barcodes.
Receipt printer
A receipt builds customer trust and prevents disputes. Shops usually use thermal printers: they need no ink, just special paper rolls.
Paper width: 58 mm or 80 mm
- 58 mm — compact and inexpensive.
- 80 mm — a wider, easier-to-read receipt, better for long orders.
Connection type
- USB — plugs straight into the computer.
- Bluetooth — no cables, works at short range.
- Wi-Fi / network — several tills can share one printer.
Before you buy
- Check that your software supports the device.
- Make sure you can customise the receipt (shop name, phone, a thank-you line).
- Check that paper rolls are easy to buy locally.
Summary
For a small shop, a simple USB scanner and an 80 mm thermal printer are enough. What matters most is compatibility with your software.
OnHasap works with any USB barcode scanner, with your phone as a scanner, and with 80 mm thermal printers connected over Bluetooth or Wi-Fi — and you design the receipt yourself. See the features.
