With the prevalence of smart phones and the popularity of the Internet, the development of tickets in recent years has rapidly spread from traditional paper forms into electronic tickets. In addition, according to the research results of international research institutions, hundreds of millions of electronic coupons will be transmitted to smart phones through the Internet or the cloud every year in the future, and the total transaction amount of various mobile payment technologies in the world will reach hundreds of billions of dollars. Mobile payment for Near Field Communication (NFC) accounts for the majority.

As can be seen from the above, the prevalence of electronic coupons has gradually become a new shopping mode for users (consumers). Therefore, application services such as high-priced ticket, VIP ticket, electronic ticket, software license, and mobile payment must be improved. Security to reduce trading risk. However, with the electronic ticket or mobile payment service Popularization, the current industry still uses the fast response code (QR code) as the main credential technology, but the security mechanism of the fast response code is still not perfect and hidden danger.

On the other hand, the current personal digital certificate is a service of a third-party electronic certification service organization. According to the usage method, it can be divided into two types: a chip-type natural person certificate and a wafer-type financial certificate. However, these two methods cannot be combined into a smart phone. It is impossible to use a smart phone for authentication.
