Introduction
For transactions to be carried out through paperless online cards, then they must be given unique codes that are stored in the database so that whenever the user wants to use it, they only have to decode the credit card no. This will act as the account number for the company issuing it.
Credit card infomation
Most credit cards no have special case numbering of either ISO or IEC numbers identified by the series 7812. This series is usually a sixteen digit number in length. This credit card no digits is composed of an identification number for the user which is six digit, an account identification number that is mainly twelve digit in length and a check digit that is usually a single variable.
To know the basic facts about the credit card no information then the card holders’ first six numbers are used as the company providing the service as its issuer identification number. This is known as the IIN. This will automatically make known the identity of the company that issued the card to the client. The rest of the numbers in the card are then issued by the company depending on the secrecy of information. This becomes their secret codes.
Most credit card no are issued by the company through various networks. But you will find that almost all companies that offer credit card services will write the four fist digits that belong to them i.e. the IIN in every card that they issue. This is done to enhance the security in the card and avoid fraud.
Apart from the IIN credit card no, there is also an extra security code that is enhanced in the last digit of the card. This numbers are found on the back of the card on the strip signature. These codes are mainly used during transactions related to credit and debit cards. Basically there are three main types of credit card no security details, first we have cvc1 located on the magnet strip. This is used when transacting by the user. Then we have the CVC2 that is used by sellers to secure transactions and finally the CVV chip which is given through an electronic process randomly.
There are various ways that a credit card no holder can keep safe their identity and avoid scams. First, in case you suspect that someone has known your personal identification number, then you have to change that information so that the person will not be in a position to transact using your card.
Features
Secondly, you can approach the company to block the existing numbers in their data base. This will make the card numbers null and void as they will not be recognized by the system. In case you want to send credit card no to another person to transact, then it is ideally not possible to send it through the emails as they may end up as spam messages to people who you did not intent to send to.
Conclusion
Before you get your credit card no, you have to know all the information about it so that it can be simple to use and apply in case of an emergency fraud.
