Some customers who visit our stores for RFID key fob copying also ask us about credit cards and whether they use the same technology. In today’s blog post, we’ll address the question: Do credit cards use RFID?
The Basics: Do Credit Cards Use RFID?
The short answer is: some do. Most modern credit cards use NFC (Near Field Communication), which is a type of RFID (Radio Frequency Identification) technology. NFC is a more advanced form of RFID and is commonly used for contactless payments.
When you tap your card at a payment terminal, that tap function is powered by NFC. It allows the card to communicate with the reader through a radio signal, making the transaction quick and contactless. So while not all credit cards use traditional RFID, they typically use NFC, which falls under the RFID family.
What’s the Difference Between RFID and NFC?
- RFID is a broad term referring to technology that uses radio waves to transmit information wirelessly. It’s used in many things, including security fobs, ID cards, and warehouse inventory systems.
- NFC is a specific type of RFID used for short-range communication (within a few centimeters). It’s secure and commonly found in tap-to-pay credit cards and smartphones.

Should You Be Concerned About Security?
RFID and NFC credit cards are designed with encryption and security features that make them safe for everyday use. While concerns about “electronic pickpocketing” exist, major financial institutions have taken precautions to ensure the cards are secure.
If you’re curious about protecting your cards, there are RFID-blocking wallets available, but for most people, they’re not essential.
