The essential difference is that the account relating to a crypto-card, instead of being supplied in euros, is in a currency such as Ethereum, BitcoinBNB, CRO and other avatars.

You take the card provided to you by Binance from your pocket to make the payment. You insert it into the terminal and type your PIN code. A debit of 0.03 ETH (Ethereum) is made in your account at Binance – the equivalent of 100 euros at the time of this writing. Binance converts this amount of 0.03 ETH into 100 euros which is paid to the trader through processing cryptographic. Note that other crypto-cards, and in particular that of, operate in “prepaid” mode: it is necessary to top up your balance in euros beforehand by selling cryptocurrencies upstream.

Visa and Mastercard support

One factor is able to reassure users of a crypto-card: they are supported by Visa or Mastercard. It just so happens that these institutions want to support the transformation digital financial services.

The advantages of a crypto-card

What are the advantages of having a crypto-card rather than a classic card? First, management costs are significantly reduced. The reliability of transactions is very high, due to the fact that the underlying technology (the famous blockchain) is extremely secure.

But that’s not all. Some crypto-cards come with bonuses or rewards, including cashback on purchases. At as at Binance, this cashback can go up to 8% if you are ready to “immobilize”, that is to say keep a certain amount in your account. This cashback is donated to cryptocurrency and therefore helps to grow your wallet with each purchase. For example, Binance rewards the user with a balance in BNB (his currency).
