FAQ

What makes SentryCard so secure?

Among several differentiators, the SentryCard’s antennas are undiscoverable until an on-card biometric authentication takes place. Once a user biometrically authenticates to the card, the microprocessor validates the match and makes the antennas discoverable again during the transaction, whether opening a door or logging into a computer.

Would utilizing the SentryCard require an organization to rip out and replace its existing infrastructure?

No, there’s no need for rip and replace.  The SentryCard is completely open-architected, meaning that it is compatible with all leading access control systems, door readers, and readily connects to the Active Directory via commonly used software (Microsoft, OKTA, PingID, VeridiumID, Windows Hello, Google, Citrix, Azure, etc.)   Sentry maintains an “agnostic” approach to access control and has the ability to integrate (or embed) any of HID’s technologies (Prox, iClass, iClassSE and SEOS) as well as the entire NXP MiFARE suite (MiFARE Classic, DesFIRE EV1 and DesFIRE EV2), allowing it to work with any existing readers.

How are the biometrics enrolled onto a SentryCard?

A user’s fingerprints are enrolled directly onto the SentryCard itself and never need to pass-thru or be stored on a database of server. This is critical in the on-going compliance requirements of GDPR (General Data Protection Rights), the CCPA (California Consumer Protection Act) and the growing number of BIPAs (Biometric Information Protection Acts).

How many fingers can you enroll on the SentryCard?

SentryCards are designed with firmware allowing the enrollment of two (2) fingers. The two fingers need to be enrolled concurrently.

Is there a certain finger that is required to enroll on the SentryCard?

No, any two fingers can be selected, a thumb from each hand is recommended.

How long does it take to enroll the biometrics?

Generally, less than 30-seconds to load two different fingers.

Can the SentryCard be transferred to another individual?

No, once the biometrics have been enrolled onto the SentryCard they are irreversible and no longer able to be changed.

How does SentryCard address issues with individuals whose fingerprints historically (either due to ethnicity or being worn-out) don’t work well with readers?

SentryCard utilizes a capacitive fingerprint sensor produced by Fingerprint Cards, a Swedish manufacture that has deployed a billion+ sensors.  The SentryCard uses a large sensor array (160 X 160 pixels) with 508 DPI resolution, enabling the most robust matching capability in the market.  There will always be exceptions, but the capacitive technology within the SentryCard has proven to overcome the otherwise most common matching issues.

What is the False Acceptance Rate (FAR) of your fingerprint sensor?

The FAR is 1 in 50,000.  That said, consider that the biometric within the SentryCard is decentralized, meaning that 50,000 unique people would have to be in possession of the card to attempt a false acceptance.  Compare that scenario again current solutions, where there could be hundreds of thousands of user biometrics in a database that one user’s biometric could be matched with.

Is the SentryCard a multi-technology card, allowing me to grandfather older ID populations?

Yes. Because a SentryCard will work with your existing infrastructure, you can integrate the use of Sentry while phasing out your existing/older ID populations.

Why wouldn’t an organization just use a mobile device solution vs. a card solution?

There are numerous reasons, starting with the understanding that a phone, although a convenient answer, is not a secure answer.  1) In the vast-majority of cases, phones are owned by the user and not the enterprise; 2) The user controls the loading of biometrics on the device; 3) Multiple biometrics can be loaded/changed on the device by the user; 4) Phones still utilize a back-door PIN code for access that can be shared/stolen; 5) Phones are always connected (Wi-Fi or Cellular) and thereby discoverable by bad actors; 6) Phones have innumerable other applications within them, allowing malware and back-door access to the device; 7) Phones aren’t allowed in most enterprises secure environments, call centers and other critical areas; 8) Imagine the number of different types of phones within an enterprise, all with potentially different levels of operating systems.  What would the help-desk burden be to manage access control issues across so many different versions?

Why is the SentryCard more expensive than my current ID-badges?

Comparing a SentryCard to today’s employee badge (a piece of plastic with an antennae) is comparing apples and bowling balls. The SentryCard is a biometric computer with over 60 components and addresses use cases far beyond just physical entry. When factoring in SentryCard’s multiple utilities and risk-mitigations it provides almost an immediate ROI.

What is the read-range of a SentryCard?

The read-range of a SentryCard is 1-2 centimeters. Again, the SentryCard is a sophisticated piece of electronics that harvests energy from the reader. It takes up to 500 milliseconds (half a second) to process multiple functions within the card itself. 

What is the expected lifespan of a SentryCard?

SentryCard is a powered-card solution, utilize both energy-harvesting as well as a lithium-ION battery. SentryCards are designed for approximately 33,000 uses, typically translating to between 3 to 5-years of lifespan, based upon 30-40 uses per business day.

Can you print on the SentryCard?

Yes, you can print directly on the SentryCard using a RE-TRANSFER printer but due to the texture on the card DTC (Direct to card Printers) do not currently work well. We recommend the HID/FARGO 4500 as well as the 5000 printers. The only caveat is that you cannot apply an additional laminate overlay on the sensor side.

Can you punch a hole in the SentryCard for use with a lanyard?

No. Due to the amount and sophistication of the electronics within the SentryCard, it is unable to be punched. That said, Sentry provides an acrylic card sheath with both a vertical and horizon tab for a lanyard that provides a convenient way for the user to access the biometric sensor for use.

I heard a comment about the SentryCard serving a “life-safety” use case. In what respect?

The SentryCard also contains a UHF (ultra-high-frequency) antennae. Working in conjunction with UHF beacons in a building the credential could provide location information of an employee. Specific to life-safety or a “mustering” use-case and working in conjunction with an existing back-end, the SentryCard could serve to report who has exited or entered the building in the case of an evacuation.
