Despite the increasing accuracy and flexibility of biometrics, one analyst says its level of acceptance in the marketplace has been "disappointing," an article at zdnetasia.com said.

Kris Ranganath, director of technology and solutions of NEC, said that recent developments allow identification using not just a fingerprint but virtually any of an individual's biometric data — iris, veins in the finger or palm or even body odor. As a result he said, both fraud prevention and user experience could be improved.

Wincor-Nixdorf regional vice president for Asia-Pacific, Ricardos Khoury, told zdnet that such technology can not only help reduce basic fraud, but can also extend banking services to the illiterate and barely literate rural masses in the region.

But while voice, facial recognition and iris scanning can now be considered mature technologies, the adoption rate remained below industry expectations, Andrew Kellett, senior analyst of IT solutions at Ovum told zdnet.
