30 Dollars - Sushi Express 爭鮮迴轉壽司

Sushi Express is a Taiwanese conveyor-belt sushi chain founded in 1993, notable for holding its per-plate price at NT$30 for over two decades — a fixed-price model rigid enough that the company issued these paper vouchers as a direct substitute for NT$30 coins at the table. The QR code links to promotional content, making this one of the earlier examples of a Taiwanese food-service coupon integrating mobile verification into the physical instrument.

Functionally scrip, not currency. Redeemable only within the chain's outlets.
