From 1998 to 2002 the forum (RFID-BB) was located on an external site. Over the  4 years, as much as 586 messages have been submitted to the forum, containing a lot of worthful information about RFID. The complete backup of the old RFID-BB can be downloaded here now.

Summary / Abstract
Originally designed for contactless smart cards in the form factor ID1, today ISO/IEC 14443 finds new applications in an increasing number of different form factors. Most famous among the new form factors are applications such as the electronic passport (e-passport) or contactless credit cards in a form factor that is only half or one third as large (“key fob”) as ID1. The need of increasingly smaller form factors however, more often leads to problems in the field, because the small transponder cannot always be read out reliably. It becomes a real problem, when the contactless data carriers are miniaturized even further, to be operated inside a mobile phone as a micro-SD or SIM card. With a passive transponder, a reliable communication with the reader can not be guaranteed any more. A proposal for a new work item in the standardization of contactless smartcards (ISO/IEC 14443), which describes the use of battery-assisted transponders, will be a helpful new approach to overcome such limitations. The following article describes the basic principle behind this new type of transponder.

Summary / Abstract
Originally designed for contactless smart cards in the form factor ID1, today ISO/IEC 14443 finds new applications in an increasing number of different form factors. Most famous among the new form factors are applications such as the electronic passport (e-passport) or contactless credit cards in a form factor that is only half or one third as large (“key fob”) as ID1. The need of increasingly smaller form factors, however, more often leads to problems in the field, because the small transponder cannot always be read out reliably. This has led to a new type of a battery powered transponder, actively emulating load modulation, to enhance the operating distance. Whereas ISO/IEC 14443 focuses on very small antennas and small transmission power to allow reliable communication distances of a few centimetres, we were looking in the opposite direction. Using quite large antennas and huge transmission power we achieved communication distances in the range of a few meters. We also learned, however, that the effort spent to enhance the reading range increases drastically with each additional meter, quickly ending up with equipment like a “broadcast radio station”. The issue presented in this paper is not linked to a future application, but describes the practical limits of a potential attack scenario.
