The Benefits of a RFID Card

Most credit cards come with RFID chips so that you can make contactless payments. These cards are also used in access control, supply chain management, and even passports for security reasons.

Although some people are concerned about credit card skimming, the risk is low. The RFID chips that power these cards only release signals when they are in close proximity to the reader.


A RFID Card is an easy-to-use way to improve security at home, in a business, or other settings. The system replaces the traditional lock-and-key method of entry, requiring an authorized user to place the card near the reader. The reader then reads the signal from the card and unlocks the door. In addition, you can use the same card to control multiple locks, saving time and money.

These cards are a great option for businesses that want to prevent theft by employees and customers. They work by detecting electromagnetic fields and transmitting a signal that is unique to each individual card. The signals are not blocked by metal materials such as wallets and purses, so they can be read from a distance. These cards are also a good choice for individuals who have a hard time remembering passwords and PIN numbers.

Using an RFID card to track items in your supply chain can help reduce costly errors such as missing shipments, product loss, and deliveries that arrive at the wrong locations. This technology also increases inventory accuracy and transparency. It allows you to instantly see the status of a shipment and its location, or the stage it is at in your manufacturing process. It also makes it easier to do cycle counts and automatically trigger reorders at safety stock levels.


Unlike traditional keys, RFID access cards are much harder to duplicate or intercept. Depending on the configuration of the system, they can even be revoked remotely, allowing security teams to monitor or change access privileges without having to physically remain on-site.

This allows for greater automation and can significantly reduce overall operating RFID Card costs, as it prevents the need to hire additional staff to handle manual tasks. Security teams can also oversee access through the use of an app on a mobile device, so they can respond to any issues quickly and efficiently.

Additionally, a key security benefit of RFID systems is that the data transmitted by these devices is encrypted, making it more difficult for hackers to clone or spoof credentials or access property. However, it is important to note that these systems can be susceptible to other forms of cyberattacks and must be configured using best practices to ensure maximum protection.

Another security feature of an RFID card is a ghost image, which is a semi-visible graphic applied to the card. This is usually another photo of the cardholder or a logo with reduced transparency, and it adds a level of visual verification to help deter fraud. This is especially useful for large organizations that may need to track multiple identities and verify all activity at each entry point.


Many RFID cards have a microprocessor that stores and processes information. This chip is usually small and can hold thousands of bytes of data. It is powered by a tiny metal coil, which converts radio waves into electricity. The microprocessor also contains the card’s unique identification number. The card’s antenna and microprocessor are surrounded by an insulator to protect them from physical abuse, high heat levels, and corrosive chemicals.

RFID chips have a lifespan of ten years or more, but they may not be able to survive in harsh environments. Passive tags, which are smaller than business cards and rely on energy from a scanner’s interrogating radio waves, have an even longer life. These tags can be embedded in a wide variety of items and operate within a range of 1mm to 10 meters.

RFID allows for the tracking of individual items, which can be scanned by a reader at any point during their production, transportation, and storage. This makes it possible to manage inventory, perform stock checks and audits, control shrinkage, and manage supply chain logistics. It is also an excellent solution for e-commerce, which relies on the ability to track items.


The cost of RFID systems can seem expensive at first glance, but the technology can actually make a significant impact on your event or mifare desfire venue. While there are up front fixed costs associated with implementing an RFID cashless system, these can easily be offset against increased revenue and lower operational costs.

Depending on the type of RFID system you require, there are various factors which will affect the price. The most important is the cost of the RFID tags themselves, which can vary significantly based on the size, shape and features of each tag. For example, a passive RFID tag can range in price from $25 and up, with additional costs for more complex packaging, special protection and longer battery life.

Another factor is the cost of the RFID scanners, which can also be a substantial investment. Luckily, the latest RFID innovations are making this technology more user-friendly and affordable than ever. It’s even possible to create RFID transponders that are small enough to be embedded in items such as lanyards and wristbands.

Finally, the software that powers an RFID system can also be costly. The complexity and scalability of the software can greatly affect the overall price of an RFID solution. Fortunately, many active RFID solutions like AirFinder offer SaaS models, meaning you can often include these software costs in your overall system quote.
