How it works
The device scans the palm in multispectral infrared light and reads its reflection. The hemoglobin in the veins absorbs some of the infrared emitting, so a pattern of blood vessels appears on the reflection. Mathematical algorithms convert the pattern to a digital code and pack it into an encrypted template file that is only 4 KB in size. To identify a person, the device scans their palm and compares the received biometric template with the templates in the database.
The palm vein pattern is individual and has many more unique features than a fingerprint. The pattern is completely formed by the age of 12 and does not change throughout a person's life.
Unlike an RFID card, a palm vein pattern cannot be lost, forgotten at home, stolen or handed over to a colleague.
The condition of the hand surface is irrelevant: the palm vein scanner accurately recognizes a person by a dirty or wet palm, a palm with cuts and calluses, and even a palm in a thin medical glove.
The latest generation palm vein scanners are completely contactless – they are hygienic, convenient and absolutely safe for health.
The vein pattern is not visible in normal light, so it cannot be photographed or faked. The device scans the palm in several IR spectra at the same time, so it cannot be fooled with a silicone dummy. Only some significant parameters of an individual palm vein pattern are encrypted in the digital template, so it is impossible to restore a full-fledged image of a hand from it. Even if an hacker gains access to the database, they will not be able to use it at all.
Wherever palm vein identification has been used, it has established itself as the most convenient and secure one among all biometric identification methods.
