San Jose Tech Museum of Innovation - RFID wristbands
Seen in the Mercury News - Museum uses RFID wristbands to provide additional services to visitors.
San Jose's TheTech Museum of Innovation has an RFID system that lets you revisit your experience. They keep the data anonymous by only recording the tag's number, not any of your personal details. After your visit, you can type in the number on their website and get back a record of your visit.
