What are the problems of RFID?

Trouble with metals and liquids: RFID has long had a difficult relationship working among liquids and metals, as both make it harder to get proper reads on assets. With metal, the problem stems from the radio waves bouncing all over the place. Liquids play havoc with RFID in that it can absorb signals sent from a tag.

How can we overcome the disadvantages of RFID?

Use active tags that are reusable. Depending on the type, you may be able to remove, relocate and reprogram them. This is a practical way of overcoming one of the major disadvantages of RFID… the high cost of active tags.

What are the negative consequences of RFID technology in supply chains?

The literature has identified a number of concerns about this high degree of RFID-enabled visibility into supply chain activities. The concerns include consumer privacy invasion, corporate system security concerns, and industrial espionage (e.g., Juels, 2006; Shih et al., 2005).

What is the limitation of RFID?

Material limitations RFID tags and labels are very specific to the type of material and size of your assets. For example, metal will deactivate the RFID antenna and the tag will not transmit at all. Using RFID on metal requires a special type of tag with a block to prevent interference with the antenna.

What are some advantages and disadvantages of using RFID technologies?

Many of the advantages of RFID revolve around the actual use in libraries and using the technology to free up librarians for duties that involve more interaction with the patrons. Many of the disadvantages revolve around the technology also, but include issues surrounding security and privacy.

Can RFID be demagnetized?

Decorative Magnets RFID interference is a common, but not the only way your access card can get demagnetized. A swipe card can get demagnetized even from something as simple as a fridge door magnet, provided you keep them close enough for a long time.

Why the RFID scanners are failing at the depots?

And there are probably another 20 factors that can affect an RFID reader’s performance but the most common reasons that keep our customer support agents employed are coupling factors, the material density of the tagged item, RFID antenna patterns, antenna cables, RFID tag density, reading speed, noise, and reading …
