The card (Visa or Mastercard) is linked to a crypto wallet or exchange. At payment the provider sells part of your crypto at the current rate and pays the merchant in fiat. The result depends on the rate, spread and conversion fee. The point is to spend crypto wherever ordinary cards are accepted, without manually cashing out.
Debit spends straight from the crypto balance; prepaid is topped up first. Also check custody: custodial cards are managed by the provider, non-custodial ones by you. Some cards offer crypto cashback.
The key parameters are the conversion fee and spread, issuance and service charges, daily and monthly limits, and supported currencies and countries. Compute the real cost on a specific offer.
Ignoring the spread and conversion fee, keeping a large balance in a volatile coin, overlooking limits and regional support, and forgetting the tax consequences of spending.

The funds come from cryptocurrency and are converted to fiat at payment; the payment network itself is ordinary.
Each conversion of crypto to fiat is potentially taxable income. Confirm the treatment with DVX.
