In this book Andrea Bauer examines the apparently simple question of the role of trust in the
development and establishment of mobile payment services. The proliferation of new payment
instruments was always associated with the condition of trustworthiness. Even if the form of
payment has changed constantly in the past (e.g. cowrie shells stones coins paper notes
plastic cards or electronic digits) the demand for trustworthiness was always an essential
factor regarding its market acceptance.What trust exactly is which functions trust has in the
use of technical solutions and which aspects and determinants of trust are crucial regarding
mobile payment services Andrea Bauer will analyze in the present work.
