However, face-brushing payment may be the most unreliable payment method in the world, and it may have failed. If your face is a payment password, and this password is recorded by countless cameras every day. Do you think this password is safe?
Under the traditional technology, it is almost impossible for a thief to have the keys of 10,000 households, guess the bank password in other people's minds and get cash from the pockets of 10,000 people.
However, in the era of Internet and big data, once a link is out of control, millions of pieces of data may be stolen. If these data are connected, it is very convenient to transfer money from your account. And this kind of accident is possible. Especially in the era when cameras are everywhere, face recognition is even more unsafe. If you suspect that the key has been stolen, you can replace the lock cylinder. If you suspect that the bank card password has been leaked, you can change it. However, if you suspect that others will use your face to pay the bill, how should you change your face? Did you cut your face several times with a knife, or did you have a facelift?
Although some countries and cities have legislated to ban face recognition technology, in some countries, cameras are increasing rapidly. First of all, it is not necessary, because not many people will forget to bring cash and mobile phones. Secondly, this payment method is really unsafe. Even if it is combined with other biometric methods, there are still unsafe factors in the era of big data. Third, it is slow and inefficient. Therefore, face-brushing payment is a kind of payment method with no future. It only applies to small amounts of money, only applies to very few occasions, and only applies to people who don't care about their own safety and privacy.
