Apple has made their first step in providing point-of-sale, or PoS, systems to other retailers. The systems are modified iPod Touches that allow employees to ring up purchases, accept credit signatures and wirelessly print receipts to stationed printers through the store; if that sounds familiar, it’s because this is the same EasyPay system Apple uses in many of its own retail stores, albeit rebranded as “ZipCheck.”

According to confirmation from the company attained by 9to5Mac, the first customer of Apple’s PoS systems is Old Navy, owned by the Gap, a company Steve Jobs sat on the board of from 1999 to 2002.

The system is only being tested in a few Old Navy stores right now, but if it’s successful, don’t be surprised if, next year, the credit card authorization you’re signing is done with your finger on an iPod Touch.
