What are the hazards of swiping face payments from vending machines?

I believe that many people know a lot about the use of vending machines. I also talked about the use process last time. There are mainly two ways to pay. 1. Cash payment 2. Alipay, WeChat scan code payment. With the development of face recognition technology, Alipay has launched a face recognition payment function. Many people have questions about this facial recognition payment technology. What is the harm of this kind of vending machine for facial payment? If you are asking about the safety hazards caused by the equipment to the human body, it is a bit too complete to say that there are no safety hazards caused by the equipment. After all, it is a radiation, and the sun has a certain impact on the human body. In a few seconds, the impact is negligible. If it is about the security of funds, any payment method has its advantages and disadvantages, which lies in how we solve the problem and prevent it from occurring. The Dragonfly payment launched by Alipay in December 2018 is the most advanced face-brushing device currently available. It is small in size, easy to carry, and low in equipment costs. It is no longer a patent of large merchants. At present, most vending machine manufacturers use Alipay's face recognition technology. Through Unicom's Alipay account, if you can't even trust Alipay, then the payment software installed on your mobile phone will hardly have much confidentiality. Facial recognition payment is a convenient payment method to put it bluntly. Don't worry too much. Secondly, the purpose of facial recognition is to pay. There should be other payment methods in the vending machine. This can be solved according to your needs. At present, vending machines have payment methods such as banknotes, Alipay, WeChat, Baidu Wallet, etc., to meet the needs of most people and provide a perfect user experience.
