The VP-II provides ultimate system usability of 99.98 percent (the percentage of unspecified adult population that is capable of using a system. The nature of biometrics products means that if one user in a user group cannot use a system, the entire group cannot adopt the system). High-usability directly results in better security because the hand vascular biometrics technology, unlike other popular biometrics technology, does not provide a ‘back door’ such as a key or numeric password. Fingerprint devices suffer from usability because some users have faint fingerprints while iris and retina scan devices may not be appropriate for people with eye diseases. On the other hand, hand vascular pattern will only be unusable if the user has severe burn wounds on both hands (eachhand is unique and either hand can be used for identification), or if both hands are missing.

The false acceptance rate (FAR) is the probability that another individual is falsely recognised as the lawful owner of the reference data. The VP-II has an FAR of 0.0001 percent. The false rejection rate (FRR) is the probability for the lawful owner of the reference data to be falsely rejected when presenting his verification data. The VP-II has an FRR of 0.1 percent.

The sensor of VP-II does not require physical contact, so it prevents enrolment of non-biometrics patterns and fraudulent use of biometrics features (like system-residual biometrics patterns). In comparison, most fingerprint scanners require users to press a finger onto the scanner in order to capture the print. There is also increased security because of the sensor’s capability to sense the user’s temperature, which implies that the hand must be a ‘live’ one.

Since there is no direct contact with the user’s vein for authentication, the device offers users peace of mind. In addition, since it involves the back of the hand, it is less invasive and poses minimal positioning problems.

Since the VP-II scans beneath the skin surface, it can be relied on to perform consistently even if the user’s hand is dirty, wet or has surface scars. Its robust physical features also make it more resistant to damage and wear-and-tear, and allows it to operate under poor environmental and weather conditions. This makes it suitable for places such as construction sites, military bases, factories, etc. In addition, since the sensor is located within the scanner, it also means it is less prone to damage and therefore requires less replacement and maintenance efforts. The product line-up of a Hand Vascular

• The Only Non-External Biometric - Cannot be easily copied and reproduced like iris, fingerprint and facial biometrics can.

• Uniqueness - Patterns are different even in twins

• Adaptable technology - High performance even with skin conditions, large scars, dirt, grime and other contamination

• Low False Acceptance Rate (FAR) – 0.0001%

• Low False Rejection Rate (FRR) – 0.1%. By comparison, iris has been measured at up to 30%

• Usability – 99.98% 1 in 5,000 might have some difficulty using it. Fingerprint technology is 95% (1 in 20)

• User Perception - Stored fingerprint scans considered invasion of privacy and iris scans are frightening for many.

• User Convenience - Equally usable for persons of different heights and mobility.

• Hygienic - Small surface contact and all surfaces coated with Nano-Silver.

• High Performance in network environments – TCP/IP Very small (208 bytes) traffic load.
