What Is A Proximity Card?

Technology makes everything easy and accessible for us. Proximity card is a contactless card readable even without inserting it into a device or using a card reader. The owner can still use the card left inside a purse or wallet.

The card looks like an ordinary 30-mil PVC card. The difference is there is a metallic antenna coil embedded in the card that stores the encoded data.

How does a proximity card work?

You may wonder how a contactless card works without a card reader. A proximity card uses a 125 kHz low radio frequency to transmit data to a door access reader. Inserting the card on the access reader, the numbers on the card are passed to the control panel of the access reader. Once the number matches the approved internal database number, it will unlock the door.

Benefits of proximity cards

Proximity cards can be used in various ways and applications. That is why many businesses have been using these cards because of several benefits.

1. Convenience

Tapping the card to a reader would lead to easier access. You can conveniently open and get into a locked door within seconds using proximity cards.

2. No codes to learn

Learning and remembering codes can be troublesome, significantly when changing passwords. Using proximity cards will spare you from remembering security keycodes. It is because proximity cards use a token-based system.

3. No learning requirements

If you will use proximity cards you need not be technology-savvy. Just hold the card within the radius required to gain access.

4. Low maintenance

Proximity cards involve no moving parts, so they don’t need thorough maintenance. There’s a lower chance to wear and tear because it does not have physical contact with the access reader.

Despite the advantages of using proximity cards, there are some drawbacks compared to RFID and smart cards. With memory capacity, proximity cards have lower memory capacity. Obviously, the card can do more if more data is stored in the chip.

Another thing is the functionality of proximity cards is limited. It is commonly used as access control because the chip can only hold a card number and facility code. Proximity cards are not totally secured as these are prone to card cloning.

Takeaway

Proximity cards are passive cards that have a limited range. You need to get it closer to the reader so that the code will be read. After verifying the code, you can then have access.
