The days of needing huge cash registers or other devices tethered to one location as a point of sale (POS) system are long over. There are a variety of POS systems available for both iOS and Android platforms.
Some mobile point of sale systems include credit card scanners that attach to the phone or tablet, while others leverage newer Near-Field Communication (NFC) technology to process a sale by having customers tap their smartphone on the POS device. Google Wallet is an example of NFC technology revolutionizing the point of sale process. There is little doubt that mobile point of sale solutions are a trend, saving small businesses money compared to larger systems.
