While new technology has simplified many business and personal transactions, it has also opened the door to high-tech crime. In this article, we investigate design options for mobile user devices that are used in legally significant applications. Such applications authorize transactions: mobile phone calls, access to an office or car, electronic payment in stores, retrieval of stored medical data, and access to information on portable computers. Digital signatiures--the electronic equivalent of handwritten signatures--are at the core of most of these applications and are explained briefly in the "Digital Signatures" sidebar. A trustworthy mobile user device should suit its purpose well and have credible quality.
