Odd Invention: Receipt Grebber

Why is it that the banks and credit card companies are so simple in their information given in reference to your purchases? Why can't they read like a receipt so I **really** know what I am spending my money on and allowing me to fine tune my finances. now I know the real reason is that all that information is considered of great value from both a marketing and privacy standpoint that disseminating it like that is to give away gold...sooo...

Has anyone seen the recent Mastercard/Visa which allows you to "wave" you card in front of them to pay for stuff? Kinda like the Mobile card did for gasoline people (and I am sure in hundreds of smaller roll outs all over the world). Well, lets add the reverse and instead of getting paper receipts, get an exact data version of the receipt and have the ability to upload that information to intelligent software on my computer. A simple little keychain toy able to pick up a certain style of signal and store that data until it is requested later.

And then let me sell my information to the fucking marketers.
