Forbes takes a look at mobile payments in a piece posted this morning that sports the provocative headline, “The death of cash.” The story actually does a pretty good job of explaining why mobile payments could be more attractive to consumers than cash — citing loyalty programs, mobile coupons, etc. — but it seems to dismiss the argument that the lack of a single solution will curb uptake in a very big way. The mobile payment industry is already very crowded, but consumers simply won’t use a half-dozen different offerings based on where they’re making purchases. We won’t see massive use until we begin to see one or two solutions begin to separate themselves from the crowd.
