Visa introduced encryption technology during its first-quarter 2021 earnings conference call. Visa CEO Alfred Kelly said in his speech that Visa is ready to make encrypted payments safer and more widely used by cooperating with more other companies. Kelly stated that Visa plans to cooperate with wallets and exchanges to enable Visa users to purchase crypto assets and allow users to use their cryptocurrency to cash in and conduct fiat currency transactions. Visa believes that cryptocurrency is digital gold, and stable currency and central bank digital currency are emerging payment methods that may be used in global business scenarios.
