Or does the cell phone become the smart card?
- IT TOPICS:Mobile & Wireless, Security
Experiments have started with cell-phone-based payment systems. Most arguments in favor of smart cards also support the cell phone alternative; indeed, it may be even better. Smart cards are something that wouldn't be inconvenient for people to carry; cell phones are things they WANT to carry. Cell phones have plenty of processing power for encryption, a keyboard for PIN number entry, and the potential for voice authentication.
However, one argument that does NOT work for cell phones is that they don't support card readers. You can't assume that EVERYBODY will carry a cell phone the way you can for a smart card, so even if you use them you need an alternative.
But when a boom is forecast for smart cards, it is possible that much of the usage will be of cards inside mobile phones.
