A crypto-funded card involves several parties and the economics explain both the pricing and where the consumer protections sit. Against [a regulated crypto payment provider](https://collectnexchange.cy/services/crypto-payment), which discloses the components separately, the margin structure becomes legible.

## The parties

**The card issuer**, usually an authorised electronic money institution, which issues the card and holds the balance backing it.

**The card scheme**, operating the network.

**The crypto provider**, holding the assets and selling them at the moment of spending.

Sometimes the same group, frequently not.

## Where revenue comes from

**Interchange.** A share of the merchant's cost, paid to the issuer on every transaction. The core revenue line for card issuing.

**The conversion margin.** What the crypto provider takes when selling your asset. Typically the largest line for the customer.

**Foreign currency margin**, where spending differs from the settlement currency.

**Monthly or issuance fees**, which vary and are frequently absent because interchange and conversion cover the economics.

## Why cards are often advertised as free

Because they are not free. The margin is in the conversion, which is not itemised.

A card advertising no monthly fee and no transaction fee, funded by selling crypto at a margin of one to two percent, is more expensive than one charging a monthly fee with a tight conversion. For online retail the calculation differs, and [a corporate crypto wallet](https://collectnexchange.cy/business-solutions/corporate-crypto-wallet) is the usual route.

## Where the protections sit

Liability for unauthorised transactions attaches to the issuer, under the rules applying to its authorisation.

An authorised electronic money institution in a jurisdiction with those rules gives a defined position. Outside that framework, the terms govern, and they are frequently less generous.

The crypto balance funding the card is a separate question governed by the crypto provider's authorisation, not the issuer's.

## The gap that matters

If the crypto provider fails, the card stops working and the funding balance is subject to that failure, regardless of how well regulated the issuer is.

The card's protections cover the payment, not the funding asset.

## The tax consequence

Every transaction funded by selling crypto is a disposal in most jurisdictions.

Funding from a stablecoin reduces gains to negligible and removes most of the accounting burden, which is the single most consequential configuration choice and is rarely the default.

## What to compare

The conversion margin, stated as a number. The foreign currency margin. Whether stablecoin funding is supported. The issuer's authorisation and the liability terms. Test the argument above against [an exchange that publishes its full terms](https://collectnexchange.cy/) before applying it anywhere else.

The monthly fee is the least important item and the one most prominently advertised.
