This is how biometric access cards work

With biometric access cards, the cardholder’s fingerprints are registered directly on the card. This way, each card is linked to a specific person. When the user enters the workplace, the card’s biometrics must match the person using the card. The card is also encoded with RFID technology (Radio-Frequency Identification), corresponding to the system in which the card is to be used. The user’s fingerprint together with the card’s RFID encoding allows the reader to accept the card. The user authenticates at the door by holding the finger on the fingerprint sensor on the card before the card is held in front of the card reader.

There is a very wide range of different card technologies on the market, and biometric cards are part of that range. The Norwegian company Zwipe has developed biometric access cards based on integrated fingerprint sensors which are well suited for organizations that want to increase security without changing their existing access control systems or their security infrastructure.

Compatible with RFID readers

The biometric cards work with RFID readers by combining fingerprints with RFID technology. This will make the cards more secure on entry. The biometric entry cards are first encoded with RFID technology, and upon delivery each user registers their fingerprints on the card. This combination provides two-factor authentication; and you can also add a pin code with the card to get three-factor authentication, which is suitable for types of entry that requires high security. Being able to use existing RFID readers instead of installing new biometric readers makes the solution cost effective.

Unauthorized access will not be possible

With Zwipe’s technology, the organization does not need to upgrade or replace its readers or backend systems. The card will only allow communication with a reader after it has been activated with a fingerprint scan, which means that unauthorized card usage will not happen, and thus also reduces fraud related to lost or stolen cards. The cards are also strong, and resistant to cracking and breaking. Nexus stores and distributes biometric pass cards, in partnership with Zwipe, across Europe.
