Self-service checkouts are increasingly common in supermarkets and chain stores, not to mention at airports. Lifehacker reader and frequent commenter 66biscuits offers a useful tip for ensuring your groceries (or tickets) are recognised quickly.
66biscuits explains that it’s all about having sufficient light:
I’ve found that for laser scanners, holding your item in such a way that as much light as possible falls on the barcode itself seems to help. It seems more consistently successful to me. I reason that more light increases the contrast of that which is being scanned, aiding the process.
I used to work on airline check-in and occasionally provided assistance to those trying to use the self-service kiosks (a little ironic), and found that if people got out of the way of the overhead lights while trying a scan they would have more success. I’ve used this same principle since then and it seems to work everywhere there are problematic scanners.
An obvious-but-still-worth-mentioning additional point: check the item and locate where the barcode is. I often see people frantically waving goods at my local supermarket, blissfully unaware that the code is pointing towards them and invisible to the scanner.
