I think Gordon's super seal is still quite easy to use, and its functions are quite complete. It can realize one-click combined billing and provide users with the function of spending first and then paying. In addition, there are consumption discounts, and points can be returned immediately after consumption, and points can be used in cash. Personally, the more friendly design is to provide the function of spending first and then paying. After all, the living expenses of migrant workers are really not much. Sometimes, when traveling, it is really difficult to collect enough money by paying hotel fees and bus fares in advance. Super Seal only needs to go through the relevant review process to get the consumption quota, without worrying about the travel expenses, and can also advance the quota from the software.
