If you’ve ever ventured into Hong Kong for more then a few days, Octopus Cards are pretty much standard fare. The rechargeable cards allow you to pay for anything from mass transportation to groceries and corner store products all via touchless radio waves. TK of SiLLY THING was on hand to design a special Octopus card in association with Radio 903′s Skyhigh Charity program. A whole list of collaborators can be seen here. The cards will go on sale this Saturday.
