Comment Already in use in Porto, Portugal!! (Score 4, Interesting) 154
Here in Porto we already are using paper tickets with a memory chip for ticketing in the public transport.
These chips are dormant most of the time and wake up when they are near the equipment that reads the data. The circuit is made with a special silver ink.
Each ticket costs around 50 cents for 176 bits of data.
For more info check out www.ask.fr (silver ink)and www.rafsec.com (thin copper)
cheers!
