I recall sitting in board meetings playing games between other tech members as we had written simple games using the earliest means of direct connect device communication well before this was common. With the introduction of the Palm VII having the first mobile cellular smart device available and being a payment processor to large dotcoms at the time we of course we would also move into mobile payments on that Palm VII. This was yet another idea well before its time but it was fun working through the engineering issues of doing payments over cellular as well as satellite long ago. I still have NIB Palm VIIs with NIB payment cradles on my tech shelf of history, maybe some day I will dig them out again to play for inspiration and curiosity.
