Trust is a subjective belief that a party will fulfill his or her
obligations according to the expectations of the trusting party. It is
crucial because gaining trust reduces fears and worries [e.g.,
3,14,17]. Transactions conducted in a mobile network are more
vulnerable and uncertain than those in the traditional settings and
Eiser, Miles & Frewer (2002) and Poortinga and Pidgeon (2005) both address this issue
and define two alternative models of the relationship between trust, risk perception and
acceptance. The model suggesting that trust leads to lowered risk perception which
leads to acceptance is referred to as the ‗causal chain‘ account of trust and is illustrated
