Point Of Sales systems are expensive, which is why companies like Square have been so successful by making them much cheaper through the use of mobile devices. Just now I spotted a familiar device in an episode of Kitchen Nightmares, and after some googling I had found out about the POSLavu. It’s a POS system made specifically for restaurants, and it uses consumer technology to make it all happen – including an iPad and iPod touches.
The setup uses an iPad as the main cash register, accessing card payments through an iPad-based reader and receipts and cash payments via an Airport Express using USB. Waiters carry iPhones or iPod touches that do the ordering, and you can even have a printer in the kitchen that communicates with this system. POSLavu is the software that makes it all work together, while the hardware is either from Apple or from Zephyr Hardware.
I find it very interesting to see how these devices can all work together like this, and I believe people who say that both the cost and the actual system is better suited for the task than made-from-scratch systems. Consumer devices that can use custom software can be blessings from heaven in situations where the only other alternative is systems that have development costs up to their elbows because of the custom nature of everything.[POSLavu]
