Smart Phone/Tablet based Point of Sale System vs. Computer based Point of Sale System:
Learning curve is quicker on smart phones and tablets than traditional computer based systems and you are not tied down to selling right by the computer
Survey done by a retail technology publication (VAR Insider) indicates that about half of all retailers want a smart phone or tablet based POS system
Same survey showed that about half of all customers look for a traditional computer cash register to pay for their items
Other Factors to Consider:
Business Volume: if your business is not generating at least $250,000+ in annual gross sales then it is tough to justify investing in a computer-based point of sale system.
Technology Needs: if you have high technology needs (complex inventory tracking, managing online & in store customer information, specific reports, etc.) then a smartphone or tablet based point of sale system may not offer everything that you need
