500 Yuan Stimulus Voucher

Taiwan's 2020 stimulus vouchers — officially the "三倍券" or Triple券program — were not banknotes in any monetary sense but a consumption-stimulus instrument issued under the Executive Yuan in response to the COVID-19 economic disruption. Citizens paid NT$1,000 for vouchers worth NT$3,000 total, with the government absorbing the NT$2,000 difference. The 500-yuan denomination was one of the building blocks of that NT$3,000 package.

Deliberately non-transferable and time-limited, the vouchers expired at the end of 2020. The watermark security feature was included specifically to deter counterfeiting in the retail environment — these circulated through convenience stores, night markets, and small businesses, not banks. Over 22 million Taiwanese participated in the program.
