Disruptive ideas start with persistent problems. Ours was sweeping, but simple: Card
payments are expensive, slow and bloated with friction.
What if there was a way to facilitate payments that are cheaper than schemes — and
deliver a better customer experience?
As pioneers in open banking, Token set out to help banks clear the decks of regulatory
complexity in 2016. Today, we are driving the shift from traditional payment methods to
bank payments with best-in-class, Pan-European bank connectivity, data and compliance
capabilities.
Token is an open banking payments platform driving the shift from card to bank payments
with best-in-class, Pan-European bank connectivity, data and compliance capabilities. With
Token’s complete toolkit, the best and brightest merchants, PSPs and banks create new
capabilities and revenue streams through our broadest, Pan-European connectivity to over
3,000 banks. Token is both bank and developer-friendly, and multi-standard by design.
