The EasyCard (Chinese: 悠遊卡; pinyin: yōuyóu kǎ) is a contactless smartcard system operated by the Taipei Smart Card Corporation for payment on the Taipei MRT(also known as Metro), buses, and other public transport services in Taipei since June 2002. Its use has since been expanded to include convenience stores, department stores, supermarkets, and other retailers. Like conventional electronic fare systems, the card employs RFID technology to operate without physical contact. They are available for purchase at all MRT stations and all chain convenience stores.

The Taipei Smart Card Corporation was established in 2000 with a total capitalization of NT$500 million. Shareholders include the Taipei City Government, the Taipei Rapid Transit Corporation, banks, bus companies, and other companies. Promotional trials of the card began in 2001, and the card was officially released in 2002. In 2008, the company changed its name to the EasyCard Corporation to increase branding and visibility.

By 2009, the company had issued over 18 million cards (over 20 million if co-branded cards are included). EasyCard transactions now account for 91% of Taipei MRT system transactions, 92% of bus transactions, and 71% of parking lot transactions. Daily transactions reached 3.1 million in 2009.
