Contactless Payments


The need for fast, hassle-free payments has driven the rise of contactless payments. These systems use technologies like NFC (Near Field Communication) or QR codes to offer a seamless, contactless transaction experience, something that has continued to grow in popularity even after the pandemic.


In fact, in Europe, contactless card payments at points of sale have increased significantly, from 41% of all card payments in 2019 to 62% in 2024.


Cryptocurrencies


The development of cryptocurrencies introduced the concept of decentralized payments. While cryptocurrencies offer advantages such as lower transaction fees and increased privacy, their volatile nature and regulatory grey area pose challenges to their widespread adoption.


Central bank digital currency (CBDC)


A central bank digital currency is essentially digital money created and guaranteed by a central bank. It represents the electronic version of a country's traditional currency, meaning that instead of physically printing money, the central bank oversees digital accounts or tokens backed by the trust and credibility of the government.


As cryptocurrencies and stablecoins gain traction around the world, central banks recognize the importance of engaging with digital currencies to remain relevant and competitive.
