Bizum is a payment service in Spain that lets users send and receive money, pay online and in shops, and make donations using a mobile phone number. Users activate it in the app of their participating bank, and each payment is confirmed in that bank app. The vendor also describes Bizum as a digital identifier, which allows signing in to websites and apps with a phone number and bank app instead of a password.
Bizum, S.L. is registered in Madrid, and the Bizum website states that the service is backed by major Spanish banks. The legal notice does not name a parent company or shareholders. The privacy policy mentions that newsletter delivery may involve transfers to the United States, with appropriate safeguards, but it does not state where the core payment servers are located. For a European organisation, Bizum is an EU-based payment method; the data-hosting location of the core service should be confirmed directly with the operator.
