Vein recognition technology is restricted to checking vein patterns of living body tissues and offers reliable reading. Moreover, vein patterns are nearly impossible to counterfeit. Many banks worldwide consequently have incorporated this technology into their ATMs to improve the user authentication procedure of these machines.While the ease of duplicating fingerprints to hack biometric systems is regularly overstated, it is a possibility. I've never even heard of anyone trying to spoof a finger- or palm vein biometric system.
The trade-off for vascular biometrics is that the sensors are typically larger and more expensive than fingerprint readers and there are fewer vendors offering vein technology. Nevertheless, certain deployments recommend themselves well to vein biometrics.
