Alex hing, here is the back of the disposable paper timing chip. Pretty high tech stuff! I think it will be used by HK races eventually.
Oh I C! It's Avery Dennison RFID chip, something similar to the security tag using in HK. Yes, it's cheap and disposable. But I thing it cannot be used for water sport, triathlon, IRONMAN, .....
