No time to check in, update your status or request a friend? Students at Swedish agency Hyper Island might have an answer for that with their new concept for the shoe brand WeSC. The idea is to place an RFID (radio frequency identification) tag in a shoe which can be placed on a reader (such as a mat) to update the wearer’s Facebook or Twitter status. It could also get them special entry to an event, free stuff or they could even make a Facebook friend request, if they stand on the mat with a new friend. Not bad, but it sure would be hard to ignore a request when they’re standing right in front of you.
