At the branches of the Health Insurance Institution where they accept applications for and withdrawals from compulsory insurance on forms M1, M2 and so on, they send customers to the bookstore to buy the form, which costs 50 cents. At the same time, the form can be printed from their website. I suggest that those who do not know about the form on the website, or who have problems, do not have a printer, etc., should be sold the form at the counter at the Health Insurance Fund and be saved the trip to the bookshop. They could also allow self-payers to register/logout online with a digital certificate.
