Today in the residence doorway there was a mascot standing next to a table of gift bags. The mascot had two phone numbers printed on its back. One for a shuttle service, the other for a particular cab company. To receive a gift bag you simply had to show the person at the table that you successfully entered both phone numbers into your cell phone’s memory…
I bet this is quite effective. Next time these people are out and about or in a rush, and in need of a ride. “Oh look this number is already in my phone, may as well opt for that service”

A slight improvement would be to have a 2D QRCODE barcode that you could scan the VCARD for the cab company/shuttle. That would mean less inconvenience when entering the numbers!
smart idea, whats in the gift bags?
