UK Faster Payments Service (2008)
The UK launched Faster Payments in May 2008, replacing a system where transfers could take up to three working days. It started with a limited set of banks and building societies, then expanded.
Early coverage was partial, and some institutions joined months later.
Faster Payments became the backbone of UK retail banking and now handles billions of transactions a year.
Shows how a real-time rail starts narrow and becomes near-universal only as institutions migrate onto it.
