‘EasyPay’ is Apple’s handheld point-of-sale system in their retail stores. In the past, the system ran on Windows Mobile and was unreliable.
Seems like that has changed. AppleInsider:
Those who have seen the system for processing credit card, debit card and cash purchases, dubbed “EasyPay touch,” said it combines iPod touch features with a magnetic stripe reader, advanced barcode scanner and Apple-written software to speed plastic and cash transactions.
Perhaps more significantly, the change to an iPod touch and Apple software will bring the entire point-of-sale (POS) system under Apple’s control. In addition, the system will have the added benefit of advertising the usefulness of the iPod touch to customers who see it being used right in front of them.
It is unknown which manufacturer partnered with Apple to create the new device. The outside shell resembles many of the protective cases sold at the Apple stores, while the back of the shell resembles several of the auxiliary battery packs sold for the iPhone.
Pretty cool.
