So this is pretty cool - Samsung has released a basic point of sale system named Tabby. Tabby is designed to run on any device with a web browser (tablet, smartphone, laptop, or desktop). Looks to be very basic but easy to learn and use. Here are some more details and you can always contact Ada Cash Register at 208-407-2202 for more information as Tabby is only sold through Samsung Dealers.
Update 21.August.2014 - I am hoping to take a more in depth look at Tabby by the end of May when I will be visiting the main Samsung US distribution facility in Minneapolis, MN.
