Technological advances have increased the diversity of payment instruments and transaction channels, heightening consumers' expectations for services in this regard. Coupled with an increasing competitiveness of the banking industry, this has emphasized the great importance of understanding consumers' choices of payment instruments. In order to meet their customers' expectations, banks have to understand what determines their choices of payment instruments. This study aims to uncover these determinants of payment instrument choice, through the use of cognitive mapping to structure the decision problem, and its combination with the Choquet integral to identify the overall preferred payment instrument from the user perspective. The results show that direct debits and electronic cards constitute the preferred payment instruments, and automated teller machines (ATMs) and point-of-sale (POS) the overall preferred transaction channels. Understanding consumers' choices of payment instrument, the factors underlying them and their interactions can contribute to better planning by banks at the distribution channel level. Strengths, limitations and managerial implications of our proposal are also discussed.
