Example: digital wallet & E-Wallet app for a fintech business in Canary Wharf (London)
Consider a fintech company in Canary Wharf (London) (global banks and fintech scale-ups). A typical digital wallet & E-Wallet app engagement would start with virtual cards, then bill payments, and finish the first release with ledger & reconciliation — usually within 12–20 weeks.
Payments would run through Faster Payments, data would be handled under UK GDPR and Data Protection Act 2018, and success would be measured on onboarding completion rate, time to approve an application and fraud loss rate.
