It is assumed that large retailing chains will expect supplying manufacturers to attach RFID tags to their products mid-term. To gain the active support of the suppliers beyond a compliance-driven "slap and ship" approach, it is pivotal to identify and evaluate economically viable applications for this group of users. Based on qualitative research with five companies, possible solutions, benefits,... View full abstract»

Radio Frequency Identification (RFID) and other wireless technologies are currently transitioning from proto-type application towards real productive systems. Possible investments into these new technologies must meet economic criteria and generate a certain business value. Anyhow, estimating all cost factors and saving opportun-ities is difficult due to uncertainty in input data. This paper prese... View full abstract»

The economic evaluation of RFID investments has not been sufficiently researched yet. This is particularly the case for the role of indirect costs and intangible benefits. Furthermore, the role of risk has been neglected in existing evaluation approaches. In this paper we present a holistic approach for the economic evaluation of RFID investments - the Extended Performance Analysis (EPA). A supple... View full abstract»

There is a lot of discussion about RFID and its possible influence on privacy. Many publications concerning this subject only concerned about the technical aspects and consequently see possible solutions in encryption techniques or physical limitations of the air interface. Others see legal restrictions as final solution. It seems necessary to come to a more general approach that includes and stru... View full abstract»

The motivation for integrating strong cryptographic algorithms into passive RFID tags is to prevent counterfeiting of goods, providing privacy protection, and granting protected access to the tag's memory. In contrast to contactless smart cards, passive RFID tags have fierce constraints concerning power consumption and chip area due to the increased operating range and the silicon costs of a passi...
