Asking which card is better is like asking which instrument in the orchestra is better, the violin or the cello. Both have distinctive sounds, but they aren't interchangeable. A composer uses a violin to create a certain sound and a cello for something different, but they each have their place. The same is true for proximity and smart cards. It's not a matter of which is better, but which one better meets your security and business needs. Let's look at each in greater detail.
Proximity cards
Also known as "contactless"cards, proximity cards use an embedded RFID microchip that's programmed with a few bits of information, like your employee's identification number and an access code. A proximity card also has an antenna that, when it comes in contact with a proximity card reader, sends those bits of information for verification. The reader compares the information on the card to the database on a remote computer to determine whether access is allowed or restricted.
The reason they're called proximity cards is that the card reader activates the embedded microchip when it comes within proximity, usually between several inches to almost two feet. Besides an ID number and access code, you can also limit access to only certain bit formats, adding a third authentication layer to your access control solution.
Smart cards
Smart cards also have embedded chips, but it holds much more information than the proximity card's chip. You get more than just access control with a smart card. You can store information to offer other functionality like financial information to make purchases using your smart card. Smart cards can also be "contact" or "contactless," depending on your needs. With the additional information you can store on a smart card, you can have higher levels of authorization for your access control solution.
Choosing the right solution
Answer the following questions to help guide you to the right ID badging and credentials solution.
- What level of security do you need for your facility?
- Do your cards need to provide more than just access?
- What are your long-term plans for IDs and security?
- Do you currently have a system in place, but need more functionality?
For example, if you currently have a proximity card system in place, you can migrate to a new smart card system using a combination proximity/smart card. This card contains both technologies to let you continue using your proximity readers while allowing for more functionality in a smart card. It's a simple solution for easing into a new system that won't disrupt your workplace.
