I saw two instances of barcode type things being messaged to phones where they are scanned this week. That probably didn't make sense, so here's a link to a guy that did a mobile boarding pass, and a link to the announcement of iphone Starbucks ordering. In both instances you receive a barcode that can be scanned to deliver information, either what you ordered at Starbucks, or your flight information at the airport.
The boarding pass guy wonders how the church could use this for childcare check-in. Sounds cool and would probably be fairly efficient. I know the two things that I'm looking for in a check-in system are safety and efficiency. JM
