If a credit-card holder has protective material protecting the front and back of the card, with the edges exposed, can its embedded RFID chip still be activated? Does the card need to be completely encased in order to protect the user's personal information? —Name...
What would be the best method for keeping tabs on such containers using radio frequency identification technologies? —Name withheld ——— The most common way to do this would be to outfit each container with an active RFID transponder set to broadcast every few seconds...
The Columbus Dispatch has posted an article on its Web site that provides a balanced view of the issue of skimming data from credit cards.
Please explain how this is accomplished. —Name withheld ——— Most countries regulate the amount of power output allowed for radio frequency identification reader antennas, in order to avoid having an RFID system interfere with other systems operating at nearby...
We are looking for a system that would be 100 percent reliable, and that could provide proof that all tags are detected at speeds of less than 55 miles per hour. —Name withheld ——— I am unaware of any RFID solution that has been classified as a "safety system." In...
I seek an RFID tag that can be mounted on adult bed bugs so that I can track the insects for a research study. Do you have any suggestions? —Name withheld ——— Bed bugs range in size from 4 millimeters to 5 millimeters (0.16 inch to 0.2 inch). A typical microchip for...
Expanded capabilities in the latest NFC phones offer application developers greater flexibility.
Is it typical for RFID systems designed for WMS applications to be Web-based, or to work on a client-server setup? —Name withheld ——— It's difficult to say anything is "typical" in the RFID industry. I would say that many conventional warehouse-, inventory- or...
What is the maximum power output? —Name withheld ——— I assume the question refers to the power output of an RFID reader antenna. Typically, the maximum power output is 1 watt of effective isotropic radiated power (EIRP). This is much lower than fixed interrogators,...
The VHA is in the process of deploying RFID-based real-time location systems at its many hospitals, and is looking to hire health-care technology managers.
Have any transponders been produced for this application? —Name withheld ——— Almost all automobiles manufactured since 1995 have had an RFID transponder embedded in the plastic housing surrounding their key grip. These 13.56 MHz passive transponders communicate with...
If so, which types of radio frequency identification technology would work best if a tag were located 3 feet below the surface of the Earth? —Name withheld ——— Burying RFID tags can prove challenging, because moisture in soil can absorb radio waves at higher...
