Cardopoly...

It seems like everywhere you go there is a company trying to get you to put their plastic keytag on your keychain or their cheap barcoded card in your wallet. Just about all the clothes stores, supermarkets, shoe stores, pharmacies, convenience stores, even my hair salon has it. I looked at my keychain the other day and was positively overwhelmed at the amount of shuffling I'd have to do to get my appropriate tag in the event that one of these merchants actually called me out on it. I propose that we let the merchant do the shuffling and that we disregard the way they look at us when we present them with the opportunity to handle our wares. I think if they want our business they ought to share the burden of our carrying for all these tags.
The wallet cards are another story. Why associate all of our information in an online account and assign it to a card for us to just lose the card and then ask our phone number to give us the discount. I'd like it if our license would work the same way. Just give your address and your license info will pull up. Why not have a thunb print database that links our names, addresses, phone numbers, credit card info, and the works. That would be great.
I read maybe 6 months ago in popular science magazine that they would be putting cell phone information out there for people to try in select cities. All of our information would be stored on our cell phone and it could be swiped at various convenience locations thus eliminating the need for a plastic card.
Ideally, if dogs can be chipped now to scan and identify them in the event of loss, then the concept of scanning a thumb to identify credit is just as feasible. I'd get into the spare thumb market now, while the concept is still relatively unexplored. Cut em off and freeze them on a metal stub. Remove yours accordingly, and save it so that you can attach the thumb of your chosing for appropriate identity theft!
I'm just kidding, but this is the wave of the future. There was a time when nobody thought you could like about your identity online and now everyone does it. Caveat Emptor. Let the buyer beware.
