The Octopus RFID Card is pretty ubiquitous in Hong Kong. Subway, train, bus, stores, parking meters, and vending machines all take it. These things are great!
Elwin looked like a kid in a candy store when he first saw this machine - I think it made his day. I chose the ludite route - using coins to alleviate myself of the bulky HK coins I had accumulated. Gotta admit, Octopus IS really cool.
We moved to Hong Kong in July '05. Much of this blog is being populated from our camera phones (treo650's) we hope that this helps us keep in touch with our friends who are now so far away!
