[Shanghai Commercial Bank’s reward flow](https://www.shacombank.com.hk/eng/personal/cards/type/cobranded/hashkey.html) feeds KYC’d order flow to HashKey: every HK$1 spent earns one point, 250 points become HK$1 in vouchers, and the customer then buys the token inside the exchange. Crypto never reaches the payment leg, unlike [Visa’s stablecoin-linked cards](https://www.visa.com/en-us/thought-leadership/innovation/stablecoin-linked-cards-monetize-money-movement), which spend wallet balances and processed about $5.2B in 2025.
