Two Swiss fintech companies, Wallee Group and Ammer Group, have developed an app that allows conventional payment terminals to accept cryptocurrencies seamlessly, akin to credit card transactions. This innovation enables merchants to process payments in Bitcoin, Ethereum, or Tether without incurring additional fees, marking a significant step towards mainstream cryptocurrency adoption in Switzerland. Merchants can easily integrate the Ammer Pay app into their Wallee terminals, enhancing payment options for customers.
