Let me take you back to the 1980’s where my interest in this whole business started with the INCA Scanning Gun. Yes that is right, this device is a COMPLETE CASH REGISTER that you hold in your hand.
When I first saw it, the inventor had the receiver positioned in a Casio CE2300 cash register. The data was transmitted by infra-red and inserted into into the keyboard buffer, the register then cashed up the sale and the drawer opened. Sadly the concept was another one of those in the category “ahead of its time” With the mobile technology available today, it wont be long before we see this concept in a mobile device WITHOUT THE NEED FOR THE INTERNET.
