Crypto card
A bank card you top up with crypto. In a shop or online you pay like with a regular card, and the coins are usually converted to local currency before the payment. Terms, fees and supported countries differ by service.
You top up the card with a stablecoin and pay for a taxi on a trip. The rate and the conversion fee are visible in the service app.
Do not load the card with your whole balance at once: keep only what you plan to spend. And before choosing, read the fees, limits and verification requirements.
