A proximity card or prox card is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. The proximity cards are part of the contactless card technologies.

What are proximity cards used for?

Prox cards are held or swiped at a card reader to gain access into a building or within certain designated areas of a building. Proximity cards or access badges are plastic PVC cards that allow a cardholder to gain entry into a building or a specific area within the confines of a building.

What is the difference between RFID and proximity cards?

RFID Card or contactless smart card using various technologies that make use of radio waves to identify objects or people. Proximity cards typically enable read-only capability while vicinity card or other RFID cards enable both read and write functionalities.

How does a contactless smart card differ from a contact smart card?

Contact smart cards are inserted into a smart card reader, making physical contact with the reader. However, contactless smart cards have an antenna embedded inside the card that enables communication with the reader without physical contact. You tap and pay. Contactless is easy and convenient.

How does a proximity card work?

Prox cards use a low 125 kHz radio frequency to transmit to a door access reader. When the card is placed on the reader, the card’s unique strand of numbers is passed to the access control panel, which verifies if the number matches an approved number in the internal database.

How do I know what proximity card I have?

First, look at the information on the front or back of the prox card. There are many manufacturers of prox cards but each card may contain physical markings printed on the card actual card….These markings may help you determine:

1. The manufacturer.
2. The card format.
3. The site and facility code.
4. The card ID range number.

What is inside a proximity card?

Prox cards look the same as the typical 30 mil PVC card but they have an embedded metallic antenna coil inside which hold the encoded data. However, other proximity products include clamshell cards, key fobs and stickers.

Is RFID same as HID?

HID cards, also called prox cards, proximity cards & access control cards, are cards that use RFID embedded technology. HID card readers are used in access control systems to open doors.

How does a proximity access card work?

What’s the difference between a Prox and proximity card?

Here are the basic differences between the two technology card options: The microchip embedded within a proximity card has only one function: to provide the prox card reader with the card’s identification number and/or site facility code number so it can be verified with a remote computer.

What does the microchip in a proximity card do?

The microchip embedded within a proximity card has only one function: to provide the prox card reader with the card’s identification number and/or site facility code number so it can be verified with a remote computer.

What’s the difference between proximity and contactless cards?

Proximity cards and key fobs are the most basic form of “contactless cards.” As the name implies, contactless cards don’t need to physically touch a reader. Instead, users simply wave them in front of a reader – reducing wear on the reader and card, and extending the life of the system.

What’s the difference between a proximity card and a magnetic stripe?

As the name implies, contactless cards don’t need to physically touch a reader. Instead, users simply wave them in front of a reader – reducing wear on the reader and card, and extending the life of the system. Proximity cards and key fobs are encoded with unique numbers that cannot be updated or changed.
