Retail payment methods are in a stage of rapid development. New service providers and technological developments enable new payment services through a variety of channels. Payment solutions are being developed based eg on the Internet and on mobile phones. Presumably, the use of paper-based payment instruments will decrease further in the future thanks to electronification in the retail payment area. In this paper we focus on card payments in Finland and certain other countries. We also look at Internet- and mobile-based payments and discuss some of the challenges related to the new solutions. The paper ends with a brief discussion of recent changes in Finnish legislation in connection with retail payments.
