The Change card is a Visa debit card, and generally, you can pay with your card in most places where Visa debit cards are accepted.
You can also use your Change card to make online payments. For some online payments, you’ll be asked to approve the payment from the Change app, or by using a code sent by SMS. This is called a 3D Secure (3DS) online payment and is an added level of security some websites ask for. Once you approve, your payment will go through as normal.
You can also withdraw cash from most ATMs that support Visa cards, unless the ATM service provider doesn’t support crypto platforms.
