Should I buy a fingerprint access control system?

You’ve probably heard that fingerprint readers are secure and reliable.
Get all the facts

Fingerprint access control and time and attendance systems are fast, secure, convenient, and can handle thousands of employees or members. They are the right solution in many, but not all cases. Here are six factors to consider when deciding if fingerprint biometrics are right for your company.

1Convenience

Convenience is one of the top reasons our customers at Suprema cite for using fingerprint readers. Employees or members can leave RFID access cards at home or in their cars, but their fingers are conveniently attached to their hands. In other words, they always carry their access tokens with them.

Beyond being user-friendly, the lack of physical RFID cards makes biometric fingerprint readers, sometimes called fingerprint scanners, the preferred choice of HR, IT, and facility management teams. When an employee leaves the organization or a person’s membership lapses, there is no card to collect in-person. Revoking access just takes a few clicks in an integrated security platform like Suprema’s BioStar 2.

2Reliability


Reliability is the top concern for Suprema customers considering fingerprint readers or fingerprint door locks. Early fingerprint readers often required more than one try and were especially prone to failure in very cold or dry environments that tend to dry out the skin on people’s fingers. Dry fingerprints look smudged or blurry to some fingerprint readers, increasing the false rejection rate.

While we cannot speak for competitors, at Suprema we have addressed the dry fingerprint issue by introducing a Conformance Decision Engine to ensure that our fingerprint readers capture accurate fingerprints. We have also introduced deep learning technology into the fingerprint analysis process. The result is 31 times greater performance indoors and 19 times greater performance outdoors, compared to other fingerprint readers on the market.

If you are in a region such as Korea, South Africa, Australia, or the Middle East, where it is especially dry seasonally or all year long, be aware that the reliability of fingerprint readers varies meaningfully by manufacturer.

3Security


Fingerprint biometrics are inherently secure. We have a full explanation of the technology that makes fingerprint readers and fingerprint door locks secure and difficult to fool in another article, but here is the bottom line: Statistically, a 500-person company is unlikely to have more than one false acceptance of a fingerprint in 37.8 years.

There are other behavioral considerations that also make fingerprint access control more secure than physical badges. People tend to leave their security badges in unsecure places where they can easily be lost or stolen, and used by unscrupulous individuals. In one widely reported example, 1,400 security badges went missing from a US airport over a two-year period. These badges provided access to areas including runways and boarding gates. When was the last time you left your finger on the table in a restaurant or in your car?

If you are looking to secure an especially sensitive facility like a data center or research lab, fingerprint readers can provide a second layer of security with two-factor authentication (2FA). To gain entry, an employee first taps an RFID access badge, and then authenticates their identity by touching the fingerprint reader.

4Cost


There are two main factors to consider when it comes to the cost of an access control system: The initial cost of buying and installing the system, and the long-term cost of maintaining the system.

The price of the most basic fingerprint-enabled access control readers are about double the cost of the most basic RFID card readers. The gap narrows, however, when considering the total cost of a system including installation, electronic door locks, and access control units.

Fingerprint access control systems may have a cost advantage when you factor in the cost of buying and replacing RFID access cards. Base prices are low for these cards but rise quickly when you add in custom printing and lanyards. Staff time spent retrieving physical cards is also an important cost consideration. We also estimate that RFID cards contribute to about 1.4 million kilograms in landfill waste every year. That’s the equivalent of tossing out about 900 family sedans. For organizations that care about sustainability, reducing plastic waste is a major concern.

As a general rule, the larger the organization and the higher the turnover, the higher the cost will be to buy and manage physical access cards.

5Guest Access

Suprema Supports Multiple Authentication Methods

The first step in using a fingerprint reader is enrollment. Before you can open doors using your fingerprint, you have to be enrolled in the system, which creates a template that maps out the unique features of your finger.

Enrolling a new user in a fingerprint access control system is quick. It only takes a few seconds. However, it is not ideal in every situation. Few employees will question the need to store a fingerprint template on a secure server managed by their employer. Guests and visitors may be less accommodating. Why store my fingerprint long-term if I’m only visiting once? How else will you use my fingerprint?

For guests, using physical or mobile access cards is likely a more convenient and quicker option. Luckily, most fingerprint readers – including all access control fingerprint readers from Suprema – support RFID cards in addition to biometrics.

6Time & Attendance


One of the main uses for fingerprint readers is as part of a time and attendance system that records when employees and contractors enter and leave. This is especially common in industries like construction and retail, which have large workforces. Ease of integration and management are two reasons fingerprint readers are popular. With Suprema’s X-Station 2, for example, managers can enroll employees and check logs directly from the terminal’s screen, without having to use a separate computer.

Another reason fingerprint readers are commonly used for time and attendance is that they keep everyone honest. Buddy punching, also called “time theft” happens when an employee checks in for an absent co-worker. It is an unfortunate practice that fingerprint-based time and attendance can solve. While it’s easy to hand your ID card or employee number to a friend, it’s far more difficult to lend them your finger for the day.
