Retailers are increasingly focusing on new point-of-sale technology to meet the demand for immediate gratification and mobile is playing a key role, according to a new survey from Boston Retail Partners.

Office Depot is the latest big box retailer to test PayPal’s point-of-sale that lets shoppers pay for in-store purchases by typing in their mobile phone number and a PIN.

Mobile point-of-sale is a hot topic in retail, especially now that it is not just Apple stores that have effective tools enabling them to complete transactions on the shop floor.

American National Bank and Guaranty Bond Bank now offer tap-and-pay as an option to pay for purchases at point of sale.

The need to execute and record tax-accurate transactions has stood in the way of widespread adoption of many efficiency-enhancing mobile retail technologies.

Roam Data has introduced an encrypted audio-coupled card reader that turns handsets into point-of-sale devices for accepting payments.

Mobile coupons are really hot. Every retailer is thinking about it – and perhaps they are losing some sleep over it too.
