M-Commerce - the mobile version of e-commerce is, well, behind "analysts projections". But who isn't? I remember somebody meeting with me way back in 1999 telling me I was crazy for not promoting the concept of m-commerce "by 2002...since $50Billiion dollars in commerce is expected then". Huh? I've purchased a book from Amazon with my SprintPCS phone while I was working out at 24Hour Fitness. (In fact, I've done most of my WAP browsing inbetween sets on the various weight machines...but I digress). The theory is that most transactions will be small, less than $20. Well, that makes sense. Exxon's Speedpass does that when gas prices are low. You can also buy some of the healthy food they sell inside with your pass too. Downloading of music, purchases from vending machines, etc., all of these will require micro-payments, and there's the problem. US banks make lots of money from credit cards, and the transaction cost is so high that there's not much profit left for purchases of this size. Europe has SmartCards, but alas we don't here yet. In Europe they have GemPlus Companies like QPass and Jalda (they work with Ericsson) are making inroads that will help. With WTLS, PKI, and other forms of security fears will be assuaged. I hope to live to see the day when all I need is my phone!
