Question

What is the “current cost of an RFID tag”?

Answer 1

RFID tags are a types of scanning system that uses smart barcodes in order to recognise items. Radio Frequency Identification, RFID tags utilise radio frequency technology. These radio waves pass on data from the tag to a reader, which then transfer the information to an RFID computer program. RFID tags are frequently used for commodities, they can also be used to track vehicles, pets, and even patients with Alzheimer’s disease, to know the Race Timings, Tracing of Assets, etc. An RFID tag can also be labelled as an RFID chip.
To be more specific, An RFID tag in its most simple form, is comprised of two parts – an antenna for transmitting and receiving signals, and an RFID chip (something like an integrated circuit, IC) which stores the tag’s ID and other information. RFID tags are connected to items in order to track them using an RFID reader and antenna.
there is such wide variation of RFID applications, there are also a wide variety of RFID tags and ways to classify them. A common way to split tags into types is inlays & hard tags. Inlays are low-priced, typically varying between $0.09 - $1.75 depending on the features on the tags. Hard tags are generally more durable and weather resistant and expensive than inlays, the price varies between $1.00 - $20.00.

Tag pricing depends on the type of tag and the amount that are being ordered. As explained above, inlays typically vary between $0.09 - $1.75 and hard tags can vary between $1.00 - $20.00. The higher the level of modification or the more specialized the tag, the more expensive it will be in comparison to typical off-the-shelf tags.
Some estimates are below
(the price is based on volume, memory, the packing of the tag itself, and whether the tag is active, passive or many other variables.
96-bit passive tags (chip and antenna mounted on a substrate) can cost between 0.091 USD and 0.17 USD per unit. If the tag is also embedded in a thermal transfer label where you can print a barcode, the price goes up to about 0.23 USD.
The most representative active tags are around 33.98 USD per unit. if you have the budget and the need, you can always opt for active tags that can cost more than 113.27 USD per unit, these usually come with a special protective case, extra long battery life or sensors.)

A few other factors that affect the cost of RFID tags the types of RFID tags

a few types of RFID tags are

Form Factor – Inlay, Label, Card, Badge, Hard Tags etc

Frequency Type– LF, NFC, HF, UHF Passive (902 – 928 MHz, 865 – 868 MHz), BAP, Active etc

Environmental Factors– Water resistant, Rugged, Temperature resistant, Chemical resistant etc

Customizable– Shape, Size, Text, Encoding etc

Specific Features/Applications– Laundry Tags, Sensor Tags, Embeddable Tags, Autoclavable Tags, Vehicle Tags, High Memory Tags etc

Specific Surface Materials– Metal mount tags, Glass mount tags, Tags for Liquid-filled items etc

finally a few queries that should be considered while selecting RFID tags (that may impact the current cost) are

What type of surface will you be tagging? On metal, plastic, wood, etc.?
What read range do you want?
Size limitations ?
Any excessive environmental conditions to consider? Excessive heat, cold, moisture, impact, etc.?

hope this clarrifies. an upvote / thumbs up is highly recommended as this will boost my morale to answer more in the future. help much appreciated
