DoCoMo Starts Cell Phone Smart Card Trial
virtualXTC writes "The Japanese phone company NTT DoCoMo and electronics giant Sony will begin a trial of cell phones with embedded smart cards with speed pass-like capabilities that will allow the user to purchase anything from travel passes to movie tickets just by placing their cell phone near an electronic reader. Potentially the smart card 'can serve as an ID card, travel pass, or login for a corporate computer network, all at the same time'. If they'd just attach a money clip to it, I could get rid of my wallet entirely."
Sure, electronic payment is convenient, but nothing says anonymous like cash.
While I love this idea in principle, I do have a few concerns before I welcome our new overlords.
What about standards? The article compares the smart chip technique to credit cards, but credit cards use a pseudo-standardized magnetic strip methodology. Are retailers to have 10 different receivers sitting at their POS terminals for 10 different cell phone/smart card providers? Along these lines - adopting early could be dangerous as one may invest in hardware that does not conform to the final standard and therefore be useless.
What about security? Until more information about how the protocol works, how security is maintained, and exactly how one can control what information is broadcasted is released, can we really trust this technology with our personal information? And this doesn't even begin to cover eavesdropping. (My tinfoil hat may be disrupting my thinking here)
When I hand my credit card to a clerk, I know exactly what information will be gleaned by the scanner from the magnetic strip. It doesn't change. What happens when I get a firmware upgrade on my phone? Can I trust that I am still secure from unauthorized access or even that my phone/ID/credit card gizmo is still only transmitting information that I approve?
One interesting alternative to this close-contact technology would be an internet-based alternative. In this scenario, my phone would use XML over SSL or some other standardized system to tell my provider to tell the POS that I am there and to relay what other information is necessary. Using this method, software-based upgrades could take care of standardization without any modification to hardware.
