That frequency range was the RFID industry's first, since the first 1980's. Typical applications include things like:
Access Control & Security
Determining widgets through manufacturing operations or in harsh environments
Hacienda animal identification (ISO 11784/11785)
OEM applications
Meta tags are made of a hard copper coils and eeprom chip then tied in into a housing appropriate for the approval.
Tags can cost from $1 to help $75, highly dependent upon quantity plus packaging. The more robust your Tag is, the higher its cost. Less expensive Tags are typically cheap and will not survive harsh circumstances. Custom Tags, the tooling of eeprom silicon wafers specific to an application, can result in a Indicate price of 20 to 30 cents, within quantities of millions.
Study ranges are typically inches to feet.
Although Tags may be used on metal and imbedded in to metal with some loss of functionality, the KHz spectrum is the most flexible to a metal environment. Simply no RFID Tag can read through steel.

13.56 MHz
So that you can lower Tag cost along with address applications of high amount Tags usage, the Tough luck.56 MHz solution was given birth to. At this frequency, a Tag's coils need not be made of hard real estate agent wrappings. The coil can actually often be a printed ink on a papers like substrate which than comes with a eeprom added to it. During the middle of to late 1990's, 15.56 MHz was the particular vogue technology that many authorities saw as a path to handling high quantity applications necessitating small Tag costs. Typical software include:
Library books
Clothes identification
Access Control
OEM programs
Typical Tag costs range between 50 cents to $1 unpackaged. Indicate prices can dip for the 20 cent level in the event that custom eeprom silicon can be sold on by the user.
Read range are typically inches to several ft ..
Metal poses a serious way to obtain interference and loss of performance. Mounting Tags on stainless steel can pose very challenging. The particular
865M - 960MHz

Since the early 2000's, 900 or 900MHz has been all the rage, the actual vogue technology of regular press bringing the RFID marketplace into a global limelight, the actual epicenter of development efforts as well as dollars. Tags at this regularity also need not incorporate a difficult copper coil. Coils may also be much less difficult to manufacture compared to 13.56 MHz and also 125 KHz, which is not its solely advantage. Hundreds or even thousands of Tag words can be identified at the same time, an expression known as anti-collision, at much greater distances, 10' with a single Target audience Antenna and 20' between not one but two Reader Antennas. Although Tag prices can be lower also perhaps at the most moderate of levels versus 13.56 Megahertz and 125 KHz, there continues to be much debate as to whether the can deliver a sub 10 cent Tag. At this moment, Tags in moderate sums can be purchased for 50 pence and quantities into the thousands and thousands can be purchased in the 30 dime range.
The primary application imagined is supply chain pursuing. The ability to identify hundreds of materials on a pallet through dock entrances from manufacturing to warehouse to delivery at a retail level spells huge Revenue in terms of wasted dollars with inventory, wasted sales caused by lack of inventory, and the palms free/human free automation of identifying what is where.
Active Tickets at 433 MHz and 2.Forty five GHz
Active Tags possess a battery thus powering some sort of Tag with greater vigor and signal strength as well as greater distances. Tag costs are higher, $20 to $70, mostly due to the additional discrete automated components necessary and the reduced quantity of Tags demanded by way of applications. Typical applications incorporate:
Highway toll Tags
Detection of private vehicle fleets in/out of a backyard or facility
Asset checking
Read ranges are typically 30', even so custom systems can read many hundreds of feet to 1 mile although these types of systems are not in a commercial sense marketed.
Having a battery, Labels do possess a finite lifetime, 5 years typical.
Metal techniques only a nominal interference point
