Kass is a free Android app developed by Íslandsbanki, available to all individuals in Iceland regardless of the bank. It is a simple and convenient app that allows users to switch costs, charge or pay with their friends. With Kass, you can pay your friends just by knowing their phone number or Cashier's username. The app also allows users to switch payments and charge their friends. Kass automatically calculates the share of each item when making payments.

One of the features that make Kass unique is the ability to take a picture of what needs to be paid. This feature adds a fun element to the payment process. Another feature of Kass is the ability to create an account with a username and add contacts from your phonebook or Facebook.
