The purpose of this study is to identify factors affecting use intension of traceability systems which designed to check product information by discerning products automatically through an automatic recognition technology such as RFID(Radio Frequency Identification) and Bar-code. For this study, we build conceptual research model based on technology acceptance model and innovation diffusion theory used widely for the MIS research fields. we selected quality of information, job relevance, training, accessibility of system, computer self-efficacy, social norms and perceived risk as external variables, perceived usefulness and perceived ease of use as medicating variables, and use intension as dependent variables. For empirical testing, data is collected from 275 nutritionists in elementary schools nationwide which adopted food traceability systems. The results show that accessibility of systems and job relevance have positive effects the perceived usefulness of traceability systems, and accessibility of systems is related with the ease of use. Also perceived usefulness, ease of use, and perceived risk are related with use intension of traceability systems. Revised model shows that computer self-efficacy has direct effects on use intension of traceability systems.
