Green Cross has partnered with Foursquare for what may be the first location-based vending machine notification service. In case you don't know, Green Cross is a Swedish company that specializes in vending machines filled with non-prescription drugs.
Green Cross has partnered with Foursquare to deliver notices to users upon check-in about deals and specials in nearby Green Cross machines. This move is groundbreaking and could very quickly lead to other companies getting on board to advertise the goods and services of their vending machines.
The Green Cross eventually hopes to tap other location-based services like Gowalla and Facrbook Places in an attempt to promote and pump up local ads and specials. I wouldn't be surprised if in a few months, you become inundated with offers about 2 for 1 Pepsis and Doritos the next time you check into a mall or train station.
