Damn you plastic

In every store I enter I find myself being asked if I have a points card for their particular store. I do agree that I enjoy collecting points when I am rewarded with free items due to my being a regular customer but it is such an annoyance to have to carry a card for every place I wish to shop. I understand that is some sort of tracking system for the government to keep tabs on my shopping habits so they can sell this information to advertisers and companies can then gear their ads to certain demographics or the company can simply do this themselves but I find it to be a giant pain in the butt and a destructive matter to the environment to be required to carry a seperate card for everyone of these stores. In my opinion I have nothing against gaining points or getting discounts but I hate wasting time searching through my wallet for the right card. Or waiting for the person in from of me to search through their wallet for that matter.... Or there entire purse to find their bloody wallet in the first palce. It would be very easy if all of these items were simply changed over to one card... or a wrist band, which you could go online, sign up for everything you wanted to and bam they would all be there with your information at hand when you got to the store... Mastercard, visa and Debit card included. Though I am sure people would find ways to steal these cards... like cutting off a persons arm to steal their wrist band but the idea seems so much simpler... Another idea would be to turn all of this information into a single data base that could be accessed through our thumbprints or fingerprints for example. Nearly impossible to steal aside from burning off finger prints or cutting off peoples hands. Why not. I would be perfectly okay with the government scanning my thumbprint and allowing me access to every card in my wallet simply by placing my thumb on a scanner... Hell in "back to the future II" The cops used peoples thumbs as their ID, or a key to their home... so why the hell not. No more need for a wallet, or purse they are hassle and a terrible christmas or fathers day gift for dad, So allow the government to track us as they are already attempting its bound to get their some day anyways so Why not now
