Signage codes, commonly known as security codes, are three- and four-digit numbers that you see printed on credit cards that help provide an extra layer of security when making transactions over the phone or digital.
Different credit card companies have different types of codes, but they basically work the same.
While you’ll want to remember the personally identifiable number (PIN) associated with your card, the security code will be available to you as long as you have the card with you. You may need to refer to the card’s security code when making an online transaction or buying something with a credit card over the phone.
Where they are.
On Visa, Mastercard, and Discover cards, the three-digit security code is located on the back of the card, at the bottom of the signature board, or in the space where you sign it on the card. On the American Express card, the security code is a four-digit number printed in ink on the front of the card, in addition to the credit card number entered (emerging).
PINs and security codes offer so much protection for credit card companies that they began ending credit card signature requirements in 2019.
What are they used for?
When making a transaction directly, you can swipe your card, insert the card into a chip reader, or tap the contact-assisted card terminal, giving the seller all your card information so they can send a credit card. the company, who then verifies the card well – all in the blink of an eye. You may be asked to provide your PIN in some transactions, such as when you use your card to withdraw money from an ATM.
When you’re using your phone to make a credit card transaction or making a purchase at a website, you’ll usually be asked to provide a security code for the card. This is partly because the seller can’t swipe or read your card. The security code gives the seller more information about you.
In addition, the security code printed on the back of the card adds an additional layer of protection. If someone takes a picture of the front of your card or sees the front and takes down your card number and expiration date, they’ll have trouble using the card if they don’t have your PIN or security number.
Overall, security codes provide an extra layer of protection against fraud and identity theft, which is good for both the credit card company and you. These small codes bring great benefits to everyone involved in a transaction.
