Exchangers by city
Exchange offices whose public rates the index reads, by country and city. A business can claim its card and publish its own rates.
How the boards work
Every card is built from the public page or channel of the exchange office: its name, city and the rates it publishes. The business claims the card with a code placed on its site, in its channel or sent to the EMpulse bot — no calls, no documents. A verified card gets a badge, the first rows of the city board, a widget with a link back and alerts when the city median moves. Own rates are shown apart from the index and enter it only as one more source with the reliability they earn; see the methodology.
