Spread of the novel coronavirus has jolted awareness of hygiene as it relates to touching surfaces such as keypads. No longer in favour are contact-based modalities including use of personal identification numbers (PINs) and keypads, and the shift has been sudden and long-term. Both customers and manufacturers were taken by surprise by this aspect of the virus’s impact and are therefore scrambling for solutions.
Immediate impact of the change includes suspension of time and attendance systems that are touch-based. Some two-factor authentication systems are being downgraded to RFID-only, abandoning the keypad and/or biometric components that contributed to higher security, but are now unacceptable because they involve touching.
Touchless biometric systems in demand
The trend has translated into a sharp decline in purchase of touch modality and a sharp increase in the demand for touchless systems, says Alex Zarrabi, President of Touchless Biometrics Systems (TBS). Biometrics solutions are being affected unequally, depending on whether they involve touch sensing, he says.

“Users do not want to touch anything anymore,” says Zarrabi. “From our company’s experience, we see it as a huge catalyst for touchless suppliers. We have projects being accelerated for touchless demand and have closed a number of large contracts very fast. I’m sure it’s true for anyone who is supplying touchless solutions.”
Biometric systems are also seeing the addition of thermal sensors to measure body temperature in addition to the other sensors driving the system.
Fingerscans and hybrid face systems
TBS offers 2D and 3D systems, including both fingerscans and hybrid face/iris systems to provide touchless identification at access control points.
Contactless and hygienic, the 2D Eye system is a hybrid system that combines the convenience of facial technology with the higher security of iris recognition. The system recognises the face and then detects the iris from the face image and zeros in to scan the iris. The user experiences the system as any other face recognition system. The facial aspect quickens the process, and the iris scan heightens accuracy. TBS also offers the 2D Eye Thermo system that combines face, iris and temperature measurement using a thermal sensor module.

Another TBS system is a 3D Touchless Fingerscan system that provides accuracy and tolerance, anti-spoofing, and is resilient to water, oil, dust and dirt. The 2D+ Multispectral for fingerprints combines 2D sensing with “multispectral” subsurface identification, which is resilient to contaminants and can read fingerprints that are oily, wet, dry or damaged – or even through a latex glove.
In addition, the 3D+ system by TBS provides frictionless, no-contact readings even for people going through the system in a queue. The system fills the market gap for consent-based true on-the-fly systems, says Zarrabi. The system captures properties of the hand and has applications in the COVID environment, he says. The higher accuracy and security ratings are suitable for critical infrastructure applications, and there is no contact; the system is fully hygienic.
Integration with access control systems
Integration of TBS biometrics with a variety of third-party access control systems is easy. A “middleware” subsystem is connected to the network. Readers are connected to the subsystem and also to the corporate access control system. An interface with the TBS subsystem coordinates with the access control system. For example, a thermal camera used as part of the biometric reader can override the green light of the access control system if a high temperature (suggesting COVID-19 infection, for example) is detected.
The enrollment process is convenient and flexible and can occur at an enrollment station or at an administration desk. Remote enrollment can also be accomplished using images from a CCTV camera. All templates are encrypted. Remotely enrolled employees can have access to any location they need within minutes.

Although there are other touchless technologies available, they cannot effectively replace biometrics, says Zarrabi. For example, a centrally managed system that uses a Bluetooth signal from a smart phone could provide convenience, is “touchless,” and could suffice for some sites. However, the system only confirms the presence and “identity” of a smart phone – not the person who should be carrying it.
“There has been a lot of curiosity about touchless, but this change is strong, and there is fear of a possible second wave of COVID-19 or a return in two or three years,” says Zarrabi. “We really are seeing customers seriously shifting to touchless.”
