The once-hyped mobile payments company is killing off its Wallet payments app and replacing it with a new app called Order, which will allow users to order food and beverages ahead of time at their favorite cafes and restaurants. For entrepreneurs, the concept of a mobile wallet seems so logical that the payments industry looks like it's ripe for disruption. If everybody is always carrying around a powerful computer in their pockets, it's natural to consider loading payment information onto that secure device as an alternative to cash or plastic cards. The problem comes when this logical entrepreneurial spirit merges with an industry segment that is classically illogical. The payments system in the United States is a mess of entrenched interests, fragmented business opportunities, old infrastructure (like point-of-sale systems), back room handshakes and cut throat competition. This behavior is not going to change any time soon, which means mobile wallets like Square are going to continue to struggle—at least until a more legitimate, easy-to-use and cost-effective solution comes along.
