"M: I know so many good ideas that failed when you tried to get the end user to buy a piece of equipment in order to perform transactions that he can perform otherwise...
If people see they need something to function in society they will pay a nominal charge as they do now for a passport or driver's license.
"M: If the item only contains an identifier then it is very easy to counterefeit it, and no one will take the responsibility to develop a transaction system with no security.
These databases can contain personal identifying info- like a photo or thumbprint that comes up when a chip is scanned. And this ID info could be encoded in the chip (as simple ROM) since it wouldn't need to be changed.
"M: With security and righst aboard the chip, you have to consider these issues. They are also closely related to ownership of the device, issuing process, personalization process, etc....
I don't see any problems- the data bases will be maintained as they are now- by the companies you are dealing with at the time. It makes no difference that they are called up by a implant rather than a card or that the same implant can call up different databases depending on what the scanner it is connected to. A scanner at a store will call up your credit card company, while a scanner at a hospital will call up your medical records.
"M: So you expect the "chip company" to replace a device it does not own?
Just as now- when you buy something it comes with a warranty where the manufacturer promises to replace it if it fails within a certain time. In the case of a chip there are no moving parts- nothing really to wear out so the manufacturer should warranty it indefinitely.
"M: I love it!!!! Do you think I can choose the type of logo, or have it tatooed elsewhere?
I'm sure these details can be worked out!
