DoCoMo Starts Cell Phone Smart Card Trial 130
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."
Just a few concerns I have (Score:5, Interesting)
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.
Don't our phones do too much already? (Score:5, Interesting)
I am not sure if I want it suddenly to hold all of my cash as well. It holds all of my personal information, dates and phone numbers, and if someone was clever they could find out alot about my servers. So currently, I believe that I have too many eggs in one basket with the functions that it carries out now. To expand those to include purchasing seems to be inviting disaster.
What the hell do I do if I lose it?

From the description, this thing works just like Esso Speedpass dongles, in that, the thing needs to be within around 2 cm ( 1 inch ) for it to trigger and transmit the needed data.
The only way anyone could eavesdrop on or steal your CC number using this system is if he has his hands in your pants. And if some unknown guy has his hands down your pants, you've got much bigger problems than your credit info.
Assuming it's also tied to a PIN you enter on your phone, it's also much more secure than the old swipe, where the waitress/retailer has full access to your card #, expiry date, and name.

Those features aren't so far fetched. In fact, why does any of that require "smartcards" in the phone? How about just the crypto features on an authentication vCard + credit card number, and a standard protocol over Bluetooth, IR, SMS, or 3G-HTTP? Scandanavians can buy snacks and pay parking meters with their phones, so why jump through a "smartcard" hoop just to get a talking wallet?

Seems like it was getting well adopted. I googled for it, but I can't remember the name exactly.
