Pretty much how all phone wallets works, so called hot wallets, not to be confused with centralized exchanges which should never be used.
An address can be in the range of 30-60 characters, you never type it all by hand due to the risk of making a mistake, on a computer you copy and paste it, then check to make sure it wasn't altered (virus and malware could do such fuckery), and on a phone you scan a QR code, great technology really, very simple and not much that can go wrong.
The store can use a public front end for their wallet which generates new keys, or simply one or more slips of papers with public keys then rotate them regularly depending on their need for privacy. Point is, the store doesn't even need to have computers there on site, it's good if they have one device tho so that they can verify the transaction on their own, this is done by simply scanning the same QR code.
As for risk of robberies it's nonexistent, because nothing moves without the private key, and no store ever needs to have their private keys on site.
It's all really convenient, and every day it keeps getting better with new UI's and tools to interact and manage it. All of it open source.
