What Is a Smart Credit Card?
A smart credit card is a card with a microprocessor chip embedded in it to facilitate more secure transactions. You can use a smart credit card by inserting it into a card reader or simply tapping it on the reader at checkout, which speeds things up compared to a card with just a magnetic stripe.
Key Things to Know About Smart Credit Cards
- Prevalence: Most new credit cards issued nowadays are smart cards, as issuers are transitioning over to them. Europe started using smart credit cards in the 1990s, but the United States didn’t really start the move until 2014.
- Technology used: Smart credit cards rely on EMV technology, but some also allow you to pay wirelessly with RFID technology.
- Bluetooth smart cards: Several companies tried to make smart cards that allowed you program multiple cards into one using a Bluetooth connection with your phone. However, none of these projects really came to fruition.
- Digital wallets: Your phone could even be considered a smart card if you use mobile wallet apps like Apple Pay, since it saves your credit card information to its memory.
It’s also useful to note that there are many other kinds of smart cards, including some debit cards, rewards cards, and personal identification cards. But credit cards are where the technology is most prominent and most advanced.
How Smart Credit Cards Work
Unlike older plastic and metal cards, which only have a magnetic stripe on the outside for a payment terminal to read, smart credit cards use computer chips. This allows them to encrypt their own information and interact with more types of readers than a normal magnetic stripe card. They can also perform multiple functions – both acting as an ID and storing funds, for example.
There are several different ways to use smart cards:
- EMV chip: This is the chip you’ll likely see on the left side of your credit card. You insert this chip into a reader, then either provide a signature or PIN for two-step verification, if required. This lends an extra layer of security to all your transactions.
- RF technology: Some credit cards allow you to make “contactless” payments, whereby information is transferred from the card to a reader without any kind of swipe or insertion. They transmit the info over a short-distance radio frequency, which is what “RF” stands for.
- Bluetooth: Bluetooth is another type of radio frequency technology. It’s what was used by smart cards like Fuze, which were supposed to you to program all your cards’ information into one device. However, Fuze and other similar startups never made it, and people generally adopted the use of mobile wallets instead.
Other Types of Smart Cards
Many people are only familiar with smart cards when it comes to credit and debit cards. But there are so many other varieties. Smart cards have almost limitless applications.
Here are some major types of smart cards:
- ID: Ever been given an ID card for work or school that lets you into a building by inserting a chip or tapping a reader? That’s a smart card, too. Some countries even incorporate smart technology into their government-issued IDs.
- Transportation: Many metro and bus systems use smart cards to both process payments and give riders points on their purchases.
- SIM: Believe it or not, the SIM card in your phone actually counts as a smart card. It’s a plastic card with a microprocessor that communicates wirelessly.
- Healthcare: Medical institutions may use smart cards as a way of storing patient medical records, in order to increase how secure the information is.
History of Smart Credit Cards
The history of credit cards dates back to the early 20th century, when merchants issued cards engraved with customers’ personal information and used them to stamp credit documents. But smart cards came a few decades later in the 1960s.
- Smart credit cards aren’t actually as new as you might think. In fact, the first patent for a chip card was filed in 1968. And the first microprocessor card patent was filed in 1976.
- In 1992, the Carte Bleu payment system in France put microchips in all their debit cards. This started the popularity of “chip and PIN” cards in Europe, leading to the vast majority of credit cards and credit card terminals using EMV technology there.
- The U.S. was rather late to the smart credit card party. We didn’t start integrating smart cards until 2014.
- Since 2014, smart credit cards have become much more widespread, and most new credit cards are now issued with an EMV chip. In fact, as of Q2 2024, roughly 91% of all card-present transactions in the U.S. were made with chip cards, according to EMVCo, the company behind the technology.
Benefits of Smart Credit Cards
There are several advantages to using smart credit cards over credit cards that only have a magnetic stripe. They include:
- Safety: Since smart credit cards are better encrypted, you’re less likely to fall victim to a fraudster and less susceptible to credit card skimming devices that attempt to steal your info.
- Convenience: Inserting your card into a card reader or tapping it is simple and usually works on the first try. Swiping a card can sometimes present problems, especially with old card readers.
- Speed: Tapping your card for a contactless payment is a lot faster than swiping or inserting it. Plus, you won’t need to provide a PIN or a signature.
Smart credit cards aren’t without their downsides. For example, not all merchants have adopted the technology to read chips yet, and damage to the chip could prevent the whole card from working.
That said, adoption of smart card readers is very widespread and growing every year, and most smart cards still have magnetic stripes you can use in old card readers. Plus, cards with magnetic stripes can stop working from damage, too. In other words, the advantages of smart cards far outweigh the disadvantages.
