When looking for access control systems, you will come across options like proximity cards and RFID cards. Wait – aren’t these the same thing? No! While both types of cards are effective security strategy tools, they have different designs and purposes. They should never be treated as interchangeable.
It’s important to know the differences between proximity cards vs. RFID cards before deciding on a new security system. With this information, you can be confident that you’re choosing the right card for your needs.
Key Differences Between RFID and Proximity Cards
One of the key differences between RFID and proximity cards is how they function. Radio Frequency Identification (RFID) cards use radio waves to communicate with a security system’s card reader. The cards have a microchip and antenna inside of them. This equipment will interact with the card reader and grant the user access to the restricted space.
On the other hand, proximity cards (sometimes called “prox cards”) don’t use radio waves. These cards work through low-frequency magnetic fields. A proximity card reader generates a magnetic field. When a prox card is brought into the vicinity of that magnetic field, the card’s internal circuit will trigger and transmit a code to the reader. As long as the code is in the security system’s database, it will recognize the card and grant the user access.

Applications and Use Cases
Another key difference between RFID cards and proximity cards is their use. Proximity cards restrict unwanted entries into buildings while providing quick, easy access to authorized cardholders. This is why proximity cards are popular security solutions for office buildings, residential complexes and school campuses. Take a look at the ID-compatible proximity cards that we have available.
RFID cards offer more data storage, so they can be used to do complex tasks beyond locking and unlocking entranceways. For instance, some corporate workplaces can connect RFID cards to attendance and time-tracking systems. So, they can use these business security solutions to help management monitor employee attendance and prevent time theft.
The Pros and Cons of Proximity Cards
The Pros:
- Cost-Effective: In comparison to access control tools like RFID cards, prox cards are much more cost-effective.
- Accessibility: Since proximity cards cost less, they are a more accessible security option. You don’t need to work for a major corporation with a massive budget in order to implement this security system. It’s an accessible option for organizations both big and small.
- Speed: Proximity cards work fast. Users will be able to access entrances quickly and efficiently.
The Cons:
- Data Storage: A proximity card’s data storage is limited in comparison to an RFID card.
- Range: While a prox card doesn’t have to touch a card reader to gain access, it does have to be in close range of it. It is not ideal for long-range scanning.
- Reliant on Power: If a building with a prox card system suffers a power outage, it can be a huge problem. Without a backup power source, the card readers will be ineffective.
Choosing the Right Access Card
With all of this information, you should be able to choose the right card system for your needs. If a proximity card system feels like the right choice, then Avon Security Products can help you take the next step. Browse through our selection of proximity cards, along with accessories like vinyl badge holders and custom lanyards.
Proximity cards are not better or worse than RFID cards, they are just different. If a prox card’s benefits and purpose seem to suit your needs better, you should invest in that security system right away.
