I’m going to be splitting this post into 2 categories. One for my question, and a second for a proposed solution (so you guys can tell me how far off base I am). Here we go.
Part one, the question. Why is it that we don’t have a chip that can do everything? Like, it’s electronics. And humans are pretty great at making these things do what we want. Why have to choose between LF, HF, Mifare, x, y, and z? What’s stopping us from building the end all be all?
Part two, my idea. I get that it’s alot of physical restrictions. But I’ve seen antennas that can do a very wide range of frequencies. Why not we make a chip that isn’t just a passive module, but a computer on its own? That way, if there is some new fancy way to authenticate, it won’t check the I’d of the chip, the program would just pretend? If anyone is familiar with network penetration, it would be like forcing associations with phones. Just have the program give it whatever it wants to hear per say.
Also, I know there are issues like having to power a machine like this, but let’s ignore that for now.
