The difference between a code pass and a travel code

One-pass code and trip code are two different concepts. One code pass refers to a payment tool, similar to a bank card, which can be used for consumption, transfer and other operations. One code pass is issued by local public transport operators or government agencies and can be used in the public transport field in this region. Trip code refers to one of the epidemic prevention measures implemented in various places during the epidemic period. The travel code is issued by the local government or health department, and users need to submit personal information and meet the epidemic prevention requirements in their area before obtaining it. Travel codes are usually used for identity verification and epidemic prevention inspection when entering or leaving certain areas or places. The validity period and scope of use of run-length encoding are also stipulated by the local government or health department. So these two concepts are different. One code is mainly used for traffic payment, and the trip code is mainly used for epidemic prevention identity verification.
