Can I buy gas with it? Can I use it at the library? Will it allow me to drive? Will it get me into Sam's Club and get me a discount at Safeway? Can I wear it on a chain on my neck to get into "privileged" areas?
We have so many forms of identification to carry nowadays. Wouldn't if be a relief to have just one form of identification, something that could be linked to a fingerprint or eye scan or PIN for important things.
If I could carry just one card, I would be very pleased....
