A study by OMFIF and Imperial College London's Centre for Financial Technology indicates that small frictions in registration and payments could significantly reduce usage. The research sets clear benchmarks: registration should take no longer than 20 minutes, peer-to-peer transfers 60 seconds or less, and in-store payments should match conventional card transactions (around 12 seconds). Separate ECB research also found that while a short video temporarily increased willingness to adopt, most of the effect disappeared after three months. A Center for Financial Studies survey reported that 62.3% of financial professionals considered the digital euro unnecessary, with roughly two-thirds expecting low consumer adoption.
