Bizum. The instant interbank P2P service Spanish banks launched in 2016: more than 29 million users (60% of the population), now also accepted in e-commerce and in stores. Linked to Bancomat (Italy) and MB Way (Portugal) through the EuroPA alliance.

Bizum has become a generational reflex (“hazme un bizum”). Spain nonetheless remains a strong card market: the legacy domestic networks (Servired, Sistema 4B, Euro 6000) have merged into a single system processed by Redsys.
