name: Fidel
description: Fidel (Enigmatic Smile Ltd, trading as Fidel API) is a card-linking and payments-data platform that lets developers
  connect Visa, Mastercard and Amex cards to web and mobile applications through a single API. PCI-compliant card-capture
  SDKs (Web, iOS, Android, React Native) securely tokenize card details, and Fidel then delivers enriched, real-time transaction
  records to the integrator's servers over webhooks whenever a linked card is used at a participating merchant. Products include
  the Select Transactions API, an Offers / card-linked-rewards API, card enrollment SDKs, and attribution & insights. Founded
  in 2015 and headquartered in the UK, Fidel operates in the United States, United Kingdom, Ireland, Canada, Sweden and the
  UAE, and absorbs PCI scope on behalf of its integrators.
