What exactly is meant when people refer to radio frequency identification? —Name withheld ——— Radio frequency identification is a broad term used to describe any method of identifying unique items via radio waves. Typically, a reader (also known as an interrogator)...
Please explain what this is. —Name withheld ——— Passive RFID systems require that a reader emit energy that is then harvested by a tag and is used to reflect back a signal to the interrogator. Automatic Power Stepping is a means by which to reduce power consumption,...
Could the tag be encased in a normal bank card and work with the recommended reader? —Robin ——— Robin, The type of reader you would require would depend on the distance at which you wanted to interrogate the bank card. You could use a passive high-frequency (HF)...
If not, where might I find a comprehensive listing of companies that make chips for LF, HF, UHF and active RFID transponders? —Guillermo ——— Guillermo, There are many different types of RFID technology. I am unaware of any comprehensive list of firms that produce...
Do any companies offer such a product—and, if so, where are they located? —Name withheld ——— The only company of which I am aware is Somark, which manufactures RF inks for animals (see RFID Tattoos to Make a Mark on Cattle Tagging). The permanent animal-identification...
VICS’ president and CEO is leaving the organization, but his leadership has helped to boost RFID’s adoption among retailers.
I plan to undertake a project in which an RFID system will be implemented in a car-door locking system. Is it possible to make duplicate cards, and can more than one card be used to operate the lock? —JP ——— Dear JP, The door's reader can be programmed to open it when...
If so, what kind of data can be communicated? —Name withheld ——— To be honest, I don't understand the question. RFID transponders (chips are only part of the device, like the CPU in a computer) are designed to communicate with a reader, so all transponders thus...
Is this feasible, or even possible? —Name withheld ——— Unfortunately, this would not work. Mifare DESfire chips are high-frequency (HF) RFID transponders with a read range of about 3 feet. You could have students place their cards near a reader located at the doorway...
End users are on RFID Connect, actively searching for products and services.
Have any studies been conducted in this area? —Name withheld ——— I have not seen any studies revealing how long this process takes, either manually or using radio frequency identification. I know that employees at Florida State University's Offices of Sponsored...
What should I watch out for? —Name withheld ——— Terrain does not impact tire tags. A tag's performance depends on the type of tag and reader used, the tag's placement, the environment in which the tag is being read and the regulations governing RF systems within the...
