Best Buy uses hardware and a specialized operating system which was developed by IBM as a point of sale system.
This system was chosen not only because of its proven track record in the POS environment but also the fact that IBM has a network of warehouses nationwide to ensure almost instantaneous repair.
Toshiba has since bought out the IBM POS business. All maintenance, and service updates are now handled by Toshiba. They will also be responsible for designing and manufacturing upgrades to existing IBM terminals and other hardware.
NFC Readers Removed
Best Buy originally installed NFC (near field communications) Readers in many of its stores. The readers are used to support contactless payment systems such as Google Wallet and Softcard.
However in March 2014 Best Buy announced that is was removing these readers from its stores. 7-Eleven and other large retailers have recently done the same.
It's not clear exactly why Best Buy removed its NFC readers. One theory is that it was an expensive technology that nobody was using.
Another theory is that as a member part of the Merchant Customer Exchange (a group of some of America's largest retailers) Best Buy will be launching a competitor to Google Wallet and Softcard in the not too distant future.Image Source: 1
