How many digits does the plastic card number usually have?
When many customers are making plastic cards, they will ask me how many digits do I need for the plastic card number? In fact, in the face of this problem, you don't have to think that you are unprofessional. I don't know, because there is no one-size-fits-all rule about the number of digits. However, after a long time of card making, some default rules will gradually be formed to reduce the troubles of customers and make card making more efficient. The following is a brief description of several aspects.
01 Whether to ignore the beginning of 0
When we make plastic card numbers, we will start from 1 at the beginning, for example, 00001, then the beginning is 0, so should we ignore it? There are also some customers who need to say from 1, 2, 3....10, 11, etc., and so on, but it is very rare to actually make it. If you have five digits, then five digits, and six digits, then six digits. This operation is simple and convenient.
02 Generally default 6-8 bits
When a card making customer asks about the number of digits, especially for plastic cards, it is difficult to manage and remember if the digits are too long, and it seems that it cannot meet the needs of consumers when the digits are short. Therefore, when making plastic cards, card manufacturers usually recommend 6-8 digits, which is more suitable and more general, and can fully meet the needs of customers, and the digits are easier to remember.
03Whether the password card is as long as possible
Some member customers pursue password card consumption, that is, consumption and management of plastic cards through password activation. Is the password card 6-8 digits? In fact, the password card generally does not use this specification. First, the password is simple and easy to be copied. Second, the password is usually a random code, which means that it should not be repeated and not Along the way, of course, the longer the number of digits, the better. Therefore, the number of digits of the password card is usually about 12-16 digits. Of course, it is not an unlimited length, and the range of the card making area of the number, the degree of harmony with the overall card, and the aesthetics must be properly controlled.
