Good afternoon. I was analyzing your project. I find it interesting, and as far as I could understand, it is a transaction system with cards, which must be programmed, referring to a particular user. Each card is associated to a user, and each card will have a unique identifier, which is placed a pin / pasword to perform the operation.
In turn, the user will have a phone, which will be sent a second random number generated, "for security", in addition to the first PIN / password.
In a database we would have something like this (The database, maybe it's relational, so the model is just big);
Name(Jhon) LastName(Will) idTarget(123456) Telephone(1122334455)
Name(Micke) LastName(Miller) idTarget(654321) Telephone(6655443322)
Anyway, I have many questions about the implementation and the questions, like.
1) Can the user have more than 1 card?
2) Can the user have more than 1 phone number?
Between Opk 1 and 2, there could be ambiguity and we would have to define everything well.
3) What types of cards do you plan to use?
3.1) NFC.
3.2) Magnetic.
I have many more questions regarding the implementation, if you can contact me, it will be a pleasure.
