Contactless Payments With an RFID Card


Contactless Payments With an RFID Card

RFID cards allow you to make contactless payments by tapping or waving your card near a reader. This technology uses radio frequencies to transfer information, which makes it safer than traditional magnetic stripe credit cards.

If your credit card is RFID-enabled, it will usually display a contactless symbol on its front or back that looks like a sideways WiFi icon.


Despite their built-in security features, RFID cards can still be hacked by bad actors. For example, attackers can use a handheld device to read the broadcast signals sent from an RFID card, clone that information onto a new RFID card, and then use it to gain access to a building or facility.

This type of attack is known as a Man-in-the-Middle (MITM) attack. Attackers can also build their own RFID scanners using off-the-shelf components, which gives them the ability to capture data between an RFID card and a reader without the victim’s knowledge. In addition, LF RFID cards are prone to electromagnetic interference from other devices and can be easily jammed, leading to the card’s inability to transmit information successfully.

There are several ways to improve security of your employees’ RFID cards and avoid these risks, including ensuring that only trusted devices can read your employee’s RFID cards. You should also limit the number of times your employees swipe their RFID cards to prevent unauthorized access to your facilities or valuable equipment. In addition, you should encourage employees to use protective measures such as RFID wallets and sleeves that shield their cards from unauthorized readers. These products are available in many online stores. However, if you want to maximize the protection of your RFID cards, we recommend integrating them with another robust system of security.


Credit cards with RFID technology can be used to make contactless payments. Instead of inserting the card into a card reader or swiping it, you simply wave it in front of the reader for a few seconds. This makes the process fast and convenient, and it also reduces the risk of someone skimming your information by scanning your credit card while you’re not paying attention. RFID credit cards are becoming increasingly common, and they’re an excellent choice for people who want to avoid the hassle of swiping their card at every store.

RFID cards also have built-in security features that prevent them from being skimmed by anyone who has a reader. They only transfer information to the right RFID Card readers, so they don’t expose your data to scammers or thieves. Additionally, RFID cards typically require a close proximity to the reader to work, which further minimizes the chances of theft.

Lastly, RFID cards can be used to open locks, which eliminates the need for a key ring full of keys for a variety of doors and locks. They can be programmed to unlock specific locks, which saves time and effort, and they’re often easier to store than a regular key. They can also be used for EV charging, which can be very useful for commuters who want to keep their vehicle charged while they’re at work or school.

Data storage

Unlike the traditional magnetic stripe credit cards, RFID cards use an integrated circuit with an antenna and a battery. This technology has a variety of uses, including access control, supply chain management, and smart labels. RFID cards also have a hard substrate, which helps them withstand harsh physical conditions. The most common substrates are plastic, but premium cards can be made from PVC, PET, ABS, wood, and other materials.

The chip in an RFID Card stores up to 32 kilobytes of data, which is enough for a unique identification code and other information. This data is encrypted, which prevents criminals from skimming it and using it for fraudulent activities. Additionally, RFID cards can be modified and overwritten by authorized security personnel.

Another benefit of RFID cards is their ability to track inventory in real time. This can help retailers minimize out-of-stock situations and improve customer experience. For example, clothing wholesaler Advanced Apparel uses RFID to pinpoint the exact location of products in a warehouse, down to the shelf and rack.

One of the most popular uses of RFID cards is contactless payment. The RFID cards can be used to make payments at retail stores, restaurants, and other places that accept contactless payment. The cards can also be used in hospitals to reduce medication errors and provide faster and more secure transportation services for passengers.

Access control

Unlike magstripe cards, RFID readers communicate with the card using radio waves. This allows for fast, contactless operation that eliminates the need to swipe or insert a card, making mifare desfire it an excellent choice for busy, high-traffic environments. Additionally, RFID credentials can be easily monitored, updated or in some configurations revoked remotely, drastically improving incident response times.

The most popular form of RFID for building security uses passive tags that operate at a very low frequency, around 140 kHz. The tag contains a small computer chip that stores data for identification and verification. When the reader is within range of the tag, it emits electromagnetic signals that are picked up by the chip and sent to a computer, which either approves or denies access to a user.

These chips are much harder to duplicate or intercept than the information stored on a magnetic stripe, and they can be read from a greater distance than other access control systems. This makes them a great option for large buildings where staff are frequently moving between departments and shifts.

RFID systems can also be used to automate time-based access restrictions. This is particularly useful for parking lots that may have different operating hours depending on the day of the week, or for businesses with rotating shifts where staff need access at multiple times throughout the course of a day.
