This study addresses an IOS (interorganizational system) adoption literature gap by proposing an integrative model of RFID (Radio Frequency Identification) adoption and incorporating the effect of perceived radicalness of technology in IOS adoption decisions. Three technological factors (perceived benefit, perceived costs and compatibility), four interorganizational pressure factors (competitive pressure, industry/regulatory pressure, net supply-chain exercised power and favorable transactional climate), three organizational readiness factors (top management support, financial readiness, IS infrastructure/capabilities) and three external environmental factors (standards stability, perceived consumer readiness and perceived stakeholder privacy) have been proposed as predictors of RFID adoption intent while perceived technology radicalness has been suggested as a potential moderator of the proposed relationships. The model was developed using existing IOS theories and constructs consistently found significant in IOS adoption studies. The model is supported using semi-structured interview data and news-report data. Testable hypotheses, methodology outline, and findings-implications discussion are presented.
