Data & methodology

Live counts: 579 payment methods, 850 banks, 154 currencies, 192 sovereign states. Plus country market reports, a news feed of scheme, regulation, launch, withdrawal and incident news, and a calendar of payment events and key dates.

We prefer primary sources: scheme rulebooks and websites, central banks, regulators' registers, bank tariffs and provider documentation. Where those are silent, we use reputable trade reporting and industry research. General references such as Wikipedia are used for background. Each entry lists its sources.

• Adoption shares. Published: taken directly from the named source. Derived: calculated from published figures, for example a payment category's share multiplied by a method's share of that category. Markets without data are shown as awaiting data; we never estimate them.
• Transaction volumes. Each figure is labelled measured (reported by the operator or a regulator), modelled (estimated from reported totals) or assumed (a stated assumption). We do not add up figures that are not comparable.
• Dates. Calendar items marked TBA or provisional are not confirmed by the organiser.
• Exchange rates. Indicative daily rates from ExchangeRate-API, updated once a day at 01:15 UTC. Not for transactions.

Catalogue changes are checked against their sources before we publish them. News items are written from primary announcements and reviewed before they go live. Exchange rates update daily.

Use "Suggest an edit" on an entry, or email support@pay.wiki with a source. We check it against the source, fix confirmed errors and reply to you.

No one can pay to be listed, ranked or to change an entry. See How pay.wiki makes money.
