According to the Science and Technology Daily, Ye Shibao, director of the Electronic Bills Center of the Zhejiang Provincial Department of Finance, said recently that electronic bills have been implemented for many years but there are still many links that cannot be reached, and the blockchain has become a key. Through the use of blockchain technology, electronic tickets can be stamped during the entire process from generation, transmission, storage, and use. The entire process can be traced and cannot be tampered with, ensuring that each circulation link can quickly confirm the authenticity of the bill, thereby achieving Settle reimbursement across regions and departments. He added that according to previous statistics, before going to the medical insurance department for reimbursement, the entire process took about 12 working days, and commercial insurance reimbursement took longer, requiring 7-60 working days. Now you do n’t have to stamp your tickets everywhere, just tap your phone to get it quickly.
