Key

For credit cards, the key locks and unlocks an encryption process that is in place to keep the credit card user safe during transactions. When a credit card is used, the electronic transferring services disguise or encrypt the credit card numbering information so that no third-party users can take this important information. The credit card encryption key is used by the credit card company to unlock the disguised credit card information that has been transferred to them during a transaction.
