Biometrics – identifying people through aspects their unique physical chracteristics or behaviour – has found steady business for the last three decades. The technology is now growing rapidly, but has it been too successful? A myriad of different, often proprietary designs now vies for business which has led to high prices and confusion about the merits of each.

Although the technology is still seen as a replacement for passwords, today’s implementations use biometrics most often as a secondary form of authentication that works in conjunction with traditional security. The day when biometrics systems completely replace PINs and passwords is drawing nearer than expected, with face and voice recognition getting closer to becoming the more modern form of passwords.

There are many forms of biometric technologies used around the world, we list those technologies and the many deployments below.
