what's in a barcode? informed consent and machine scannable driver licenses
Drawing on theory and methods of Value Sensitive Design [2] we investigated the social and value implications of the addition of barcodes to machine scannable driver licenses. In particular, we focused on the value of informed consent, user knowledge, and understanding. Twelve Washington state driver license holders were interviewed. Results indicate that participants in this study were largely unaware of the nature of the information in the barcode, and the potential uses of such information. Moreover, with increasing knowledge, participants developed a sense of concern regarding the potential misuse of information. In our discussion, we focus on the importance of informed consent and design suggestions for machine scannable driver licenses.
