Maximising Efficiency with Cloud and SaaS Banking Software

Central bankers split on CBDC future

  This is about widely available digital cash, it is not about wholesale and it is not about bank accounts. m-pesa in Africa, predominantly Kenya, is account based mobile money.

This means there will have to be caps on the size of payment and balances in wallets.
