Go to the bank and take your heart.

Password, password, verification code, all the things that need to be entered, all throw away. Replacing these with heartbeat recognition, making it easier and safer to log in to bank accounts-Halifax Bank has taken the first step in the UK bank's use of heartbeat recognition technology.

The bank, which is part of Lloyds Banking Group in Britain, has a heart-nymi wrist strap that looks like a watch. As long as the wrist, with the other hand touch the top of the sensor, Nymi can identify the pulse of the user's signal, which is known as the electrocardiogram. In addition, Nymi also installed another set of sensors to detect whether the user has been wearing it, if the electrical signal is not detected, it will automatically shut down.

Nymi's developer is a technology company based in Toronto, Bionym. The company also provided the Royal Bank of Canada with the same service, in addition to testing the band for Halifax.

Halifax is not a maverick. According to Bussiness Insider, the world's largest banks are seeking security measures other than passwords. In February this year, RBS also launched a new service that allows users to log on to their bank accounts on a single fingerprint basis.

The Halifax Bank says heartbeat recognition is better than fingerprint and iris recognition, and heartbeat is the most vital signal of the body, and is less likely to be hacked and forged. "You can forge a person's fingerprints, but you can't forge a person's heartbeat," the spokesman said. ”

But the technology has a high demand for the environment, and it is rumored that Apple Watch initially intended to use a pulse wave recognition technique similar to the technology for user identification in Apple Pay, but because the accuracy rate is not up to the request. But Apple is unlikely to give up the effort, and they have hired a lot of mobile health experts to do research. And more and more hardware vendors are developing similar products, and there will be more and more scenarios for using biological codes instead of passwords in the future.
