As you well know, it is difficult keeping up with technology. The demise of the hand held computers is a fine example. At one time the PALM was a leader in technology. It no longer is a player. The hand held computers have all evolved to cell phones.

With that change we migrated from the PALM to a Tablet PC. Where will it go next? Wherever it goes, we will be ready.

64-bit computers are now common place. Our first Windows program was a 16-bit version of RationPRO. We are now moving towards 64-bit programs.

All of our programs can utilize RFID and collect data using a rugged tablet computer from Mobile Demand.
