Some limitations quickly occurred: This separation isp not relevant anymore since you can have type A or type B memory or microprocessor cards, and we ended up with two competing technologies in 144443-3 same standard. Could you re-phrase this sentence: I don’t like that you can easily fabricate this one – and it is not defined what to do in that case.

Maybe in an effort to phase out type A?

I don’t fully understand it. Email Required, but never shown. Nowhere in the iso standard is written that uid3 cant be 88 only uid0 cant be But iwo it is not correct and the general director of the company I am working for will definitely come to look at what we are doing with two such cards in his wallet. I know it is very low probability 1: Can I find more details somewhere?

Cryptography depends on an attacker not, by sheer luck, finding the right key on the first try; mechanical engineering is all “oh all these iron atoms are aranged in a neat metal grid, so the probability of a crystal fracture going through the whole steel beam supporting this skyscraper is really really small”. Practical standards do practical implications.

Obviously, no hash is free of collisions, as long as the hash is shorter than the hashed data — but the probability of something randomly changing the hashed data to false data with the same hash is so small, it can be neglected in practice.
