Taiwan has a high density of 24-hour convenience stores, which, in addition to the usual services, provide services on behalf of financial institutions or government agencies, such as collection of parking fees, utility bills, traffic violation fines, and credit card payments. They also provide a service for mailing packages. Chains such as FamilyMart provide clothing laundry services, and it is possible to purchase or receive tickets for TRA and THSR tickets at convenience stores, specifically 7-Eleven, FamilyMart, Hi-Life and OK.
