The work to develop Swish started as a collaboration between six of Sweden's largest banks. Together, Danske Bank, Handelsbanken, Länsförsäkringar, Nordea, SEB, and Swedbank and Sparbankerna own Getswish AB, and more banks have joined. The banks are responsible for designing offers, terms, and any fees for Swish to their customers. You can find more information about the terms that apply to your bank on their website.
