Can RFID tags work when they are attached to metal surfaces or embedded within metal products?

AYes, some technologies allow RFID tags to work on metal or within metal products

BNo, metal surface reflects the radio wave and thus interferes the operations of RFID tags

CNo, RFID tags only work with plastic products

DYes, all RFID tags can be used in every environmental conditions

Show Suggested Answer

Suggested Answer: A, E

RFID tags are the small devices that can be embedded in labels or attached to tags which work with radio transmitters and/or receivers to identify themselves.

RFID tags can be used to do the following:

- Track individual items

- Track boxes of products, cages of products and pallets

- Track containers with multiple loads

- Locate equipment within a building

- Trigger alarms should equipment or stock be removed without authorisation.

RFID devices have a very small integrated circuit incorporating a small memory capability - many are smaller than 2mm square and 2mm thick. Despite its size, many can hold 2000 characters of data.

RFID operating rage depends on the radio frequency used, receiver capability and the environment. Some tags are only readable from under 1m, others can have a 100m range.

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 an RFID block to prevent interference with the antenna. Liquid products can also affect the reliability of the RFID signal. To use RFID tags in specific environ-ments, some technologies are needed to support them.

No way, metal just messes with the signals!

I thought RFID tags only worked with non-metal materials, but I could be wrong. Option C seems too limiting, though.

I practiced a question similar to this, and I think it mentioned that not all RFID tags can work on metal. So, I might lean towards option A.

I'm not entirely sure, but I feel like metal can cause interference with RFID signals. Maybe option B is the right choice?

Hmm, I'm a bit confused on this one. I know metal can interfere with RFID signals, but I think there might be some special tags that can handle it. I'll have to review that part of the material.

I'm pretty sure some RFID tags can work on metal, but I'll need to think through the details to be sure.

I remember learning that metal can reflect RFID signals, so I'm guessing the answer is no, RFID tags can't work on metal. But I'll double-check to make sure.

Okay, I think I've got this. The code sorts the two containers, then merges them together. The output should be the combined, sorted elements from both containers.

C is the right answer. If you want your RFID tags to work, just wrap them in foil. Problem solved!

B is definitely the right answer. Metal is a known interference for RFID signals. I can't believe they'd even put an 'all RFID tags work on metal' option on here!
