WHAT DOES RFID TAGGING MEAN?

RFID Tagging is the placing of tags onto assets to enable those assets to be managed.

For RFID enabled items like access cards or an Oyster card for example, the RFID tagging process is part of the manufacturing process. It would not be classed as RFID tagging.

For items that are‘tagged at source’, again this would not really be what the industry classes as RFID Tagging. When something is manufactured there are often many labels attached during the process, if that manufacturer puts an RFID tag on the item or packaging it is part of the overall process, classed as source tagging.

RFID Tagging really refers to the retrospective tagging of assets, many different types of assets.

Those assets could be library books, power tools, IT equipment, files, patient records, they are all classed as assets.

The process of RFID Tagging means that these assets have a tag placed on them, usually the tag has an adhesive back, then some reference to the item is programmed onto the RFID tags microchip.

Not all tags have adhesive on the back, it depends what they are meant to be attached to.

Once the asset has a tag attached it can be read by an‘RFID Reader’. Usually there are some security features built in so only the desired RFID Reader can get data from the tags.

What is a chipless RFID tag?

“Chipless RFID” is a generic term for systems that use RF energy to communicate data but don’t store a serial number in a silicon microchip in the transponder. Some chipless tags use plastic or conductive polymers instead of silicon-based microchips. Other chipless tags use materials that reflect back a portion of the radio waves beamed at them. A computer takes a snapshot of the waves beamed back and uses it like a fingerprint to identify the object with the tag. Companies are experimenting with embedding RF reflecting fibers in paper to prevent unauthorized photocopying of certain documents. Chipless tags that use embedded fibers have one drawback for supply chain uses—only one tag can be read at a time.
I’ve heard that RFID doesn’t work around metal and water.

Does that mean I can’t use it to track cans or liquid products?
Radio waves bounce off metal and are absorbed by water at ultrahigh frequencies. That makes tracking metal products, or those with high water content, difficult. However, good system design and engineering are beginning to overcome this shortcoming. Low- and high-frequency tags work better on products with water and metal. In fact, there are applications in which low-frequency RFID tags are embedded in metal auto parts to track them.

In addition, the size of small UHF RFID tag enough to be embedded into small item for tracking usage, such as it can improve the efficiency of management and heighten the security in asset tracking applications.

In the information ages, the small UHF RFID tag with the high performance and low cost help the organizations across industries all over the world address many issues by the advance technology. And with the power of RFID, there will be fewer errors, increased automation and the low cost with the labor pool since the latest small UHF RFID tag with the top technology has been widely used in many places. Overall, it can believe that the technology of RFID will be regarded as one of newly top technology in the near future.

RFID in Industrial Environments

Radio Frequency Identification (RFID) Technology is indispensable in many industrial environments. If you operate in a challenging environment and need fast, accurate, real time data, talk to OPP IOT specialists about an RFID solution for tracking and managing your inventory, whether consumables or fixed assets.

A typical RFID package consists of:
* RFID tags which can store up to 100 times the data of barcodes, ensuring you can keep track of all the details you want about your inventory such as lot and serial number, size, manufacturer, vendor, expiry date, user, location on production line and anything else you might want to know.
* RFID printer which can be desk top or mobile and print a range of tags.
* RFID reader which can be active or passive, fixed or mobile, incorporated into a handheld computer or standalone, depending on your particular operational needs.

Types of Memory in RFID Tags

Gen 2 RFID tags are comprised of an antenna and a chip (more accurately called an integrated circuit, or IC). The ICs for Gen 2 tags contain four types of memory:
* Reserved memory
* EPC memory
* TID memory
* User memory

When starting your application and selecting a tag, in order to know about how much memory is on each tag’s IC, you can check the specifications page on each tag’s data sheet. To learn the properties of each memory bank, we have outlined them below:

Reserved Memory:
This memory bank stores the kill password and the access password (each are 32 bits). The kill password permanently disables the tag (very rarely used), and the access password is set to lock and unlock the tag’s write capabilities. This memory bank is only writable if you want to specify a certain password. Most users do not use this memory area unless their applications contain sensitive data. It cannot store information besides the two codes.

EPC Memory:
This memory bank stores the EPC code, or the Electronic Product Code. It has a minimum of 96 bits of writable memory. The EPC memory is what is typically used in most applications if they only need 96 bits of memory. There are some tags that have the capability of allocating more bits to the EPC memory from the user memory. EPC memory is your first writable memory bank.

TID Memory:
This memory is used only to store the unique tag ID number by the manufacturer when the IC is manufactured. Typically, this memory portion cannot be changed.

User Memory:
If the user needs more memory than the EPC section has available, certain ICs have extended user memory which can store more information. When it comes to user memory, there is no standard in how many bits of memory are writable on each tag. Typically, the extended memory is no more than 512 bits, but there are some high memory tags with up to 4K or 8K bytes of memory. This is the second writable memory bank for Gen 2 ICs.
