  1. Hi, Can i get a copy of you password generator? (or explanation about is is also good). Thank you!
  2. If my EM-cards-only reader (=reader A) also reads the card from brand B, this means brand B cards are EM cards, no? Otherwise that reader could not read them. So if they are EM cards, why do other EM cards (brand A) are not even being read on the brand B reader? Thank you for the reply and thinking along with this, but I do not completely agree with that it is just a reader specification issue..
  3. Hi, I am trying to understand how "card reading" actually works. And there is an issue I do not completely get: We have cards (EM 125KhZ) from brand 'A'. When using them on a system from brand 'A', they work pefectly. When using them on a system of brand 'B', they also work. On the other hand, when wa take a card from brand 'B', they work on the system from brand 'B', but they will not work on the brand 'A' system. First T thought all had to do with the card numbers, and their factory codes. But when I wrote an empty card with the same factory code, it did not work. Even more: I copied the card into a new card, and even the new card did not work, while the original card works perfect. So my question is now: How is this possible?
