With the introduction of digital media, publicly available networks and the development of the Information Society, identity has become a pressing contemporary issue with wide ranging implications. Identity is a complex concept and a problematic issue, in which countries, businesses and the public engage. All sectors – whether public or private- are thus requiring increasingly efficient and secure means with which to identify the people behind transactions and to authenticate their identity, especially electronically. Identification is the process whereby an entity is recognized and its identity established. RFID and biometrics are some of the most famous new means of electronic identification (eID). Studies on identification systems covering technological, economic, social and legal aspects have provided some concrete support to the development of these tools. However, one key aspect for the adoption of eID has not yet been widely studied, if at all: the key determinants of the citizens’ intentions to adopt such services. This paper aims to fill this gap by investigating key determinants of people’s intent to adopt new identity-based services. A conceptual model based on TAM and DOI theories was proposed, including other individual determinants of technology adoption such as perceived risks, privacy concerns, innovativeness and trustworthiness.
