With Wonderful Payments, the authentication and approval of each payment is carried out by your own bank. This means you use the same security as you would when making any payment with your bank. Wonderful Payments will never ask donors to give access to their bank login details or password to anyone other than their own bank. As a donor, you are in charge and choose what data to share, when to share it and for how long you give access to it.
Open Banking uses software which has been thoroughly tested and implements a number of different security systems. Furthermore, Wonderful Payments and Open Banking are regulated by the Financial Conduct Authority. Only apps and websites which are regulated by the FCA or a European equivalent are able to implement Open Banking.
Open Banking users are also covered by data-protection laws and the Financial Ombudsman Service should any issues arise.
