Researchers at the University of Pennsylvania have one-upped "smart" credit cards with embedded microchips: Theyve developed a technique that lets ordinary card users program in their own spending parameters.
Penn computer scientist Carl A. Gunter presented the work at the recent European Conference on Object-Oriented Programming in Darmstadt, Germany. The technology could let employers better manage spending on corporate cards or permit parents to get teenage children emergency credit cards usable only at locations like car repair shops, hotels or pay phones.
"Banks and other card issuers have long been able to set general parameters, such as credit limits," said Gunter, professor of computer and information science at Penn, "but most have little interest in setting finer limits because the process is cumbersome and expensive to manage. Wed like to open up these kinds of additional programming capabilities to ordinary people whod like to take responsibility for restricting use of a card in some specific way. Users would decide what limits are needed."

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
