ИСТИНА

In the nearest future, millions of customers will come to grips with a new class of mobile gadgets which are expected to invade retail and service environments soon, namely mobile POS-terminals and PIN-pads. The latest models of mobile POS-terminals have all functionality of a high-end smartphone (a variety of apps running under operating system, large touchscreen, powerful multimedia capabilities, and all types of wireless communication including GPRS, Bluetooth and Wi-Fi) plus NFC, the possibility to accept credit and loyalty cards of three types (magstripe cards, smartcards and contactless cards like MasterCard PayPass or Visa payWave) and a printer. Mobile POS devices can revolutionize the whole retail and service ecosystem and radically transform the behavior and social roles of customers and sales personnel. In our presentation, we describe our recent project on the user interface design for mobile POS-terminals and present guidelines for designing GUIs for this new class of gadgets.
