As a Hangzhou native, please provide a rational suggestion for the rapid development of travel consumption cards.

For example, "A validity period must be added to the card", "Although this is a good thing, you cannot consume uncontrollably, issue less, limit it, and prevent piracy", "I think development must come little by little, not It is too hasty, and it makes sense to truly improve convenience for people.” Some simply commented: “This kind of benefit can bring convenience to citizens” and “Travel consumption cards are really good and should be developed more quickly to allow all tourists to enjoy convenience.” Some students gave better answers, such as "Increase the scope of tourism, all museums are free of charge, and the discounts are increased", "After applying for the card, you will be given a free map indicating the usage location, scope and discounts", "Categorize the user groups, and they can be divided into "Student version, senior version", "QR code recognition function can be added to make card swiping faster" and so on.
