I have a question about RFID tags that work without a battery. I want to know what reading distance has been reached—both the highest and the longest. —Faiyadh Shahid ——— Dear Faiyadh, First, let me point out that active tags have a power source (usually, but not...
Has any such research been undertaken? —Name withheld ——— I reached out to GS1 and MET Labs to find out if such testing has been performed, but it appears that it has not. MET Labs conducts a great deal of environmental testing, such as ultraviolet (UV), infrared...
Can it be connected to a SAP system, for example? —Name withheld ——— Absolutely. The value of radio frequency identification is that it provides greater information regarding an item's location and movements. Typically, enterprise resource planning (ERP) applications...
Please explain how this occurs. —Name withheld ——— Technically speaking, it doesn't. Radio waves don't travel from one radio to another—they travel from a transmitter to a receiver. Devices that both transmit and receive are called transceivers. Radio waves are part...
I recently came across an old MIT Web site about Physical Markup Language (PML) that has missing sections and apparently has not been updated since 2002. I searched the Web for other sources of information about this subject, but there seems to be very little out...
I work on a very large project, and am interested in purchasing an RFID solution. We need a system that can show the locations of our materials, a lot of which end up lost or stolen—our construction site is so large that we cannot store everything in warehouses. We...
I am attempting to conduct research about very small radio frequency identification tags. I see that Hitachi released a tag in 2007 with dimensions of 0.05 millimeter by 0.05 millimeter, but I haven't seen anything since, nor have I found similar, or smaller, tags...
Would it be possible to set up an online financial Web application in which a user would have a virtual account and be able to pay for items via a proximity card using NFC technology? —Name withheld ——— It would be technically feasible, but it might not be practical....
I am looking to obtain a large quantity of far-field RFID readers. What is the maximum distance of such readers' range, and which companies make them? —Caesar ——— Caesar, When you say "far-field RFID readers," I assume that you are referring to passive...
Has RFID Journal reported on any deployments in that area of the world? —Name withheld ——— We have not had the opportunity to report on any libraries in that region. However, according to a recent scientific paper, titled "RFID in the Egyptian Libraries: Case Study,"...
Do you have a timeframe of when to expect this development? —Name withheld ——— Like many questions sent to this forum, the answer depends on what you mean by "paper" and by "RFID." Not all paper is the same, just as not all radio frequency identification systems are...
Our company is looking for ultrahigh-frequency (UHF) readers, both handheld and stationary, that can operate at temperatures as low as -40 degrees Celsius (-40 degrees Fahrenheit). So far, I've only come across a version from TagMaster. Are there any others? —Name...
