While we could easily see this coming, it's still good to hear the news more directly: Isis has confirmed that its delayed mobile wallet system will arrive on October 22nd. The company's marketing lead Jaymee Johnson tells us that the NFC-based commerce should start in the previously mentioned Austin and Salt Lake City areas. We haven't been given a formal device list, but "as many as" 20 smartphones should be compatible by the end of the year. We can think of at least four. More details will follow on the day in question, although we already know that the cash-averse will need an Isis app, a special SIM card and compatible SmartTap terminals at stores. That's a lot of conditions that have to be satisfied just to lighten the strain on our pockets -- all the same, we'll take it when the alternatives are moving slowly.
