Frequently Asked Questions

The aim of most auto-ID systems is to increase efficiency, reduce data entry errors, and free up staff to perform more value-added functions, such as providing customer service. These would cost more than a standard RFID label that could be used on plastic items.

Different frequencies have different characteristics that make them more useful for different applications. The next thing to consider is the amount of memory and type required. RFID technology is a labor-saving technology so it's likely that some workers will laid off.

If short-range means 10 feet, then you would need a passive ultrahigh-frequency UHF transponder. In closed loop applications, global functionality is not necessarily needed, but if the tagged item is shipped from one continent to another, a wide band tag design is needed.

Their read range isn't as far -- typcially less than 20 feet vs. If a label is ripped, soiled or falls off, there is no way to scan the item. Can you recommend which ones we should buy?

Other tags can have a serial number written to it once and then that information can't be overwritten later. The read range of passive tags tags without batteries depends on many factors: You would need to set up a tagging station, at which a tag would be applied to each asset a mobile phone, for example.

The tagged object itself or space reserved for the tag might constrain the physical size of a tag. Then it becomes more complicated. Depending on the application, there can be several environmental conditions, which the tag is exposed to. Back to Top How much information can the tag store?

Most passive RFID tags simply reflect back waves from the reader. They are ideal for scanning objects with high-water content, such as fruit, at close range. The two are different technologies and have different applications, which sometimes overlap.

Data Protection Choices

Since they can be read in milliseconds, it appears that all the tags are being read simultaneously. So the system has to be set up so that if one reader reads a tag another reader does not read it again.

Another feature to take into account is how the tag can be fixed. In general, decreasing the tag size will decrease the performance. A specially designed tag, which we call a hard tag, is needed when the tag is placed directly on metal.

VeriChip also has clients around the world that want to use human implantation as a form of identification. The encapsulated tag is also the right choice if the tags needs to survive mechanical impacts.

Reader devices and tags can be selected totally independently based on other requirements in your application. It is notable that stated reading distance is theoretical, open space reading distance and may be shorter due to the improper use of the tag or reader.

There is a huge variety of different kind of tags available with different properties. If you need a recommendation for a systems integrator, you can e-mail editor rfidjournal. Each item can individually be labeled. Bar codes are inexpensive and effective for certain tasks. The readers would send data back to the database to indicate an item had left the building or returned.

Most of those jobs also have other components, such as moving products or restocking shelves. Reader and tag communication are not orientation sensitive. RFID uses the low-end of the electromagnetic spectrum. With read-write chips, you can add information to the tag or write over existing information when the tag is within range of a reader, or interrogator.

Gen2 is the right choice. This is called reader collision. It is likely that RFID and bar codes will coexist for many years.We are looking for short-range passive tags and readers (not handheld) for use on electric cables.

Can you recommend which ones we should buy? —Name withheld It would be difficult to recommend tags and readers without knowing more information about your deployment. For instance, what do you mean. "RFID technology is not in and of itself the issue. RFID is a minor miracle, with all sorts of good uses," said Simitian.

Healthcare is an ever-changing entity and technology is constantly advancing. This technology can be both good and bad and, while most technology is thought of as a good and positive advancement, some technology is not.

We are looking to buy an RFID system to manage the movements of items into and out of our organization, such as laptops, computers, furniture, smartphones, cameras and so forth.

The system should be able to record when an item leaves the premises, when it returns, how long it has been out and to.
