Inside of a credit card, there is an EMV chip with 8 contact pins that facilitates EMV transactions, which are safer than “swiped” payments. If your credit card is contactless-enabled, there is also a tiny RFID chip and a long, winding antenna inside the card, which allow for contactless payments via RFID technology. Typically, all of these elements are encased between 2 sheets of plastic – technically, polyvinyl chloride acetate (PVCA) – that are laminated together.
What you won’t find inside of a credit card is a power source, even though most credit cards issued in the present day have EMV chips embedded in them and increasingly come with contactless payment capabilities. Instead, the chip and antenna are powered by chip-enabled or contactless-enabled payment terminals when you check out at a store, for example. In other words, your credit card is not electrified when it’s sitting in your wallet. Rather, it’s dormant until you insert it or “tap” it on a chip-enabled payment terminal. Of course, magnetic stripe (“swipe”) payments are also still accepted at terminals that aren’t EMV-enabled, and you can still type in your credit card information to pay for something online.
Ultimately, credit cards are made to be durable. They go through a lot in the average day, after all. So, unless you’re intentionally peeling the two layers of PVCA apart, or you use your credit card so much that it’s falling apart, you may never see what’s inside your credit card. Just know that the EMV chip – and, if your card has the sideways Wi-Fi symbol on it, the contactless antenna – are quietly working every day to make your transactions safer.

FAQs
A chip card is a standard-size plastic debit or credit card that contains an embedded microchip as well as a traditional magnetic stripe. The chip encrypts information to increase data security when making transactions at stores, terminals, or automated teller machines (ATMs).
What is a credit card with a secret chip inside it? ›
What does the transition to chip cards mean for you? A microchip makes it less likely your payment card will be used for a fraudulent transaction in person, such as at a store.
Where is the antenna in a credit card? ›
When you hold your card close—usually a few inches or so—to a card reader, its antenna picks up a signal and activates the chip. This antenna is the thin copper wire you see in the CT scan that traces three of the card's sides before coiling around the dual-interface EMV (Europay, Mastercard and Visa) chip.
What data is stored on a credit card chip? ›
5. What information is on a chip card? The microchip embedded in the card stores information required to authenticate, authorize, and process transactions. This is the same type of account information already stored in the magnetic stripe.
Do credit cards have antennas? ›
If your credit card is contactless-enabled, there is also a tiny RFID chip and a long, winding antenna inside the card, which allow for contactless payments via RFID technology.
Can you spoof a credit card chip? ›
Debit cards and credit cards alike are susceptible to shimming. With a shimming device installed on an ATM or point-of-sale terminal, a crook can steal the data contained on your credit card's chip. They then can use the data to create a fake card.
Can credit cards with chips be hacked? ›
Yet, as thieves will do, there's a new technique called shimming that allows for even chip card information to be stolen from unsuspecting cardholders. Shimming uses a thin reader called a “shim” that fits into a card reader slot at a retailer or ATM.
Are credit card chips hackable? ›
In general, yes. Chip cards are safer and more secure than traditional credit cards that only have magnetic stripes, because all personal information is encrypted and tokenized for each transaction. However, there are devices that can enable scammers to steal EMV chip information.
Is there gold in a card chip? ›
Yes. Gold is used in the manufacturing of SIM cards due to it being a very excellent conductor of electricity. Other than this, it is also very durable. However, each SIM card contains very little amount of gold, and you need thousands of SIM cards to be able to extract a few grams of gold.
Do credit card chips contain gold? ›
The answer is YES, but it's not that obvious. Every banking card is a well-designed compound made up of metals (copper, nickel, gold, aluminum, iron), resin, glass, silicon, and plastics (PVC, PET).
The chip is an extra measure to protect your account, but it is not a trackable feature of a credit card.
Where is the RFID chip located on a credit card? ›
The contactless chip in a credit card is usually located on the front of the card, near the center or on the left-hand side.

Are credit card chips gold? ›
As credit card chips become the standard, the days of swiping may soon be over. Known as EMV chip cards or chip-and-PIN cards, these cards are embedded with a small gold- or silver-colored microchip to securely manage your transactions.
Is the chip in a credit card magnetic? ›
Instead of a magnetic strip that you swipe, most credit cards now have an EMV chip that you insert into a card reader or even use to pay contactlessly. Luckily EMV chips aren't affected by magnets. However, scratches or prolonged exposure to water can cause damage or make them stop working altogether.
Is a credit card chip RFID? ›
15 to 20 percent of bank cards feature RFID chips. This means, most probably, your credit card comes with an RFID chip.
Is there an RFID chip in my credit card? ›
Credit cards with RFID transponders usually have a symbol on them that resembles a representation of energy from a reader. Sometimes, you can actually see the RFID antenna embedded within the credit card.
