EasyPay

Summary
EasyPay is an app used by Apple Store employees. It is a payment system used in Apple Stores. Apple, in the past, used Infinite Peripherals Linea Pro iPod Touch solutions as part of their POS system. Currently, instead, they use another device which can read credit cards' chips and which integrates a keypad on its back, used to enter the PIN code. According to Oracle, the EasyPay app was developed by David Francis - at that time at FTSInfoTech - who now works together with Touch2 Systems to sell similar solutions.

As of May 2014, Apple is replacing 4th generation iPod touches used as POS with iPhone 5s, probably for enhanced hardware, Touch ID, and maybe ahead of the end of iPods.
