Why we do this is that, if your system need a series of UID number,like 1,2,3,4,5... then it can be written with the reader continuously. And when one user gets lost in their card, he just need change the card, do not need modify anything from database and system. Besides, if people have their favorite number, such as 8888, it can be customized.
