The user's e-voucher has to be activated and also needs to be bound to the affinity account before he/she can use his/her health insurance for his/her immediate relatives. However, for those who have successfully bound their e-vouchers, they can use their family members' health insurance accounts through the e-voucher's affinity account. Users only need to present their e-Medicare vouchers and swipe their cards when they visit the doctor and buy medicine. In other words, users who want to use the health insurance family account need to activate and bind it first, and then scan the QR code of health insurance with the code scanning device at the billing personnel to make health insurance payment. The MediShield e-voucher is the only identity credential for all MediShield participants' online MediShield business, and can currently be used for purchasing medicines at designated pharmacies, settling medical bills at designated medical institutions, and inquiring about MediShield accounts, among other things. In a nutshell, after binding the health insurance affinity account, you can use the health insurance e-voucher of your family members. After activating the health insurance e-voucher, you can access the supported hospitals/pharmacies through the health insurance e-voucher page. Just present the e-voucher when purchasing medicines or seeking medical treatment to pay for the relevant expenses
