The Square Mobile Card Reader will allow you to swipe credit cards into your smartphone or tablet, and the Square Register App makes it super easy to turn your device into a customizable checkout register. Perfect for the traveling businessman or even a chain of retail stores swapping out oldschool registers for iPads, Square Register accepts all major credit cards and has a simple pricing plan – either 2.75% per transaction or a flat $275 monthly fee. Compatible cash drawers and receipt printers are also available.
If you’re looking for something between an iPad and iPod touch, check out the Samsung Galaxy Tab. This 7″ screen mobile tablet is bigger than a phone, but still easy to tote around. Running off of the Android platform with a 1GHz processor, you’ll be able to surf the web, read books, play games, and much more. Monthly or pay-as-you-go data plans from T-Mobile will keep you connected, and Wi-Fi can be used in hot spots. A rear 3-MP camera supports photo and video, and a 1.3-MP front camera is also included for video chatting.
