- A separate Pay to Save card.

- Customers in Spain comparing B100 account options and the Pay to Save card.
Health and habits in saving
B100 frames banking around health, combining everyday accounts with saving tools and a card. Saving can be linked to daily habits, such as reaching step goals or spending less time on social media, and all account information is available in the app. The card is part of a plan that directs part of each card payment toward collecting plastic from the sea, which gives the brand an environmental focus. Customers who want a service that feels modern and easy to use will find the app at the centre of the experience.
Regulation and deposit protection
B100 is a trade name of a credit institution based in Spain. That institution is supervised by the national central bank and appears in its register of banks under a codification number. The brand also sits within the deposit protection scheme for credit institutions, which protects deposits up to a set limit per depositor. The legal notice sets out the company's registered details, including its tax identifier and commercial registration.
Our full take
Online banking brand of ABANCA in Spain with three online accounts without fees, two of them interest-bearing, and a debit card. Deposits are covered by the Spanish deposit guarantee fund up to 100,000 euros.
