RFID products fall into two basic categories: Passive and Active. Passive tags do not have batteries and have indefinite life expectancies. Active Tags are powered by batteries and either have to be recharged, have their batteries replaced or be disposed of when the batteries fail.
RFID products are then broken up into different frequencies. Tags and Antennas are tuned or matched much the same way as a radio is tuned to a frequency to receive different channels. These frequencies are grouped into Four basic ranges: Low Frequency, High Frequency, Very High Frequency and Ultra-High Frequencies.
LF： low Frequency range:30KHZ-300KHZ;RFID USES:125KHZ
HF： HIGH Frequency range:3MHZ-30MHZ;RFID USES:13.56MHZ
VHF： VERY HIGH Frequency range:30MHZ-300MHZ;RFID USES:Not used for rfid
UHF： ULTRA HIGH Frequency range:300MHZ-3GHZ;RFID USES:868MHZ,915MHZ
Each frequency range has its advantages and disadvantages. Europe use 868 MHz. for its UHF applications while the US uses 915 MHz. for its UHF applications. Japan does not allow the use of the UHF frequency for RFID applications. Low Frequency tags (LF) are less costly to manufacturer than Ultra High Frequency (UHF) tags. UHF tags offer better read/write range and can transfer data faster then other tags. HF tags work best at close range but are more effective at penetrating non-metal objects especially objects with high water content.
Once a frequency range is determined, then it is time to choose an antenna that best fits the application. Antennas come in all sorts of sizes and shapes. The size of the antenna determines the range of the application. Large antennas used with Active Tags can have a range of 100 feet or more. Large antennas used with Passive Tags generally have a range of 10 feet of less. There are dock door antennas (some times called Portals) that allow a forklift driver to drive between two antennas. Information can be collected from the tags without the forklift driver having to stop. There are antennas that mount between rollers on conveyors for reading/writing from below. While other antennas are available that mount to the side of or above the conveyors. Handheld Reader/Writers are available as well.
Controllers are available to communicate with most Networks (Ethernet, DeviceNet, ProFibus, etc). They typically have serial ports for programming and data transfer. Controllers are usually shipped with programming software to set-up and customize the application. Controllers typically operate on 120VAC or 24VDC.

What are NFC tags ?
NFC (near field communication) is a wireless technology which allows for the transfer of data such as text or numbers between two NFC enabled devices. NFC tags, for example stickers or wristbands, contain small microchips with little aerials which can store a small amount of information for transfer to another NFC device, such as a mobile phone.
What information can you store ?
There’s a whole set of different data types you can store on an NFC tag. The actual amount of data varies depending on the type of NFC tag used – different tags have different memory capacities. For example, you may choose to store a URL (web address) or a telephone number. A standard Ultralight nfc tag can store a URL of around 41 characters, whereas the newer NTAG213 nfc tag can store a URL of around 132 characters.
Usually, this information is stored in a specific data format (NDEF – NFC data exchange format) so that it can be reliably read by most devices and mobile phones.
Could someone change my NFC tag ?
NFC tags can be locked so that once data has been written, it cannot be altered. For most tags this is a one way process so once the tag is locked it cannot be unlocked.
Encoding and locking are two separate actions. NFC tags can be re-encoded numerous times until they are locked.
How can I encode NFC tags ?
The easiest way at the moment is to use an NFC enabled mobile phone such as the Nexus S running Android or a newer BlackBerry or Nokia. Just download a suitable App and you can be encoding your tags in minutes.
Which phones support NFC ?
At the moment, not very many. But that’s changing and it’s changing quickly. If you want to be ahead of the game then get yourself sorted with NFC now !
Here’s a well maintained list of NFC enabled phones.
What else can I do with NFC tags ?
Like the number of NFC enabled phones, the number of NFC Apps is growing quickly. For example, you can already download Apps which will allow you to encode tags to turn your phone’s wifi or bluetooth on or off – or open your favourite weather page. Encode a tag for your office desk and just tap it to change all your phone settings.
What’s all this about mobile payments ?
A lot of the press you see about NFC tags will be about mobile payments. It’s the same technology but whereas we are talking here about using NFC to transfer a web address or simple data, NFC payments are a lot more complicated and involve a mobile wallet on your phone and all sorts of other things. While the momentum behind NFC is likely to be driven by mobile payments, the technology is capable of much more.
Will NFC tags replace QR Codes ?
That’s a big question and Kimtag think that the answer is probably not.
We generally feel that QR Codes and NFC tags sit alongside each other and both have their advantages and disadvantages. We think that the user experience with NFC tags is generally better and in the instances where the additional cost of using an NFC tag is less relevant to the overall cost (for example on a wristband, brochures or posters), it would be our preference.
However, QR Codes don’t require the user to be so physically close, are free to print and are able to be read by most current smartphones (albeit with a suitable app).
What batteries do they take ?
That’s the clever thing about NFC tags. They don’t require batteries. They get their power from just being near a powered NFC device, for example a mobile phone.
How close do you have to be to the tag ?
The answer of course depends on your phone and the tag itself, but generally you need to be within a couple of centimetres (an inch).
How do Kimtag use NFC Tags ?
The NFC tags you can purchase from Kimtag are pre-encoded with your Kimtag web address and are locked to prevent others from messing with them. They are ready to use with your Kimtag immediately. Anyone tapping or scanning your NFC tag will be taken through to your Kimtag connection page.
So how do I get my NFC tags ?
If you want to use NFC but don’t want to use the Kimtag connection system, you can buy NFC tags, stickers and products from any number of places on the internet – just do a Google search for NFC Tags !
Otherwise, just set up your OPRFID connections page like you would normally. You can either list all your connections or set it up instant redirect to link directly to your social network, webpage or file. Then visit the OPRFID Store and order some NFC tags, wristbands or other NFC items. If you aren’t sure, then get started with a couple of the standard white sticker NFC tags and you’ll see what it’s all about.
Humans have been using brands to recognize livestock animals for hundreds of years. In prehistoric times it was more of a ritualistic act. During the middle Ages in Europe, hot branding was used to identify the owner of livestock. This has sustained all the way through history. In the American West branding is often associated with trail drives and cattle rustlers. Electronic animal identification is a significant technology in contemporary animal husbandry offering immense benefits. Low-frequency applications are high-tech within the radio frequency classification of animals.
Ultra-high-frequency (UHF) submissions are appropriate for this purpose. Still, UHF systems have inadequacies through their defenselessness to metallic surfaces and liquids. Therefore, the reflection and amalgamation of electromagnetic radiation in the animals’ environment is often challenging. Modern farming techniques dictate careful and accurate control of livestock, including the skill to tell apart individual animals. Livestock ear or recognition tags have been generally used to identify livestock for centuries. The use of identification tags has led to vast improvements in competence in agricultural industries, in addition to enhanced safety and lower costs to consumers because disease and genetic mutations are more easily identified with each improvement in the tracking of livestock.
There are many types of identification devices in use, such as rings, tattoos, and identification tags. The concluding ones are attached to the ear of the animal. Normally they include inkjet or laser markings which recognize, for example, the animal on top of the location where it was raised. EID tags are small “button-like” tags that are positioned in the ear. Each EID tag has an exclusive 15-digit number printed on it, and the number can also be read by scanning the tag with an EID reader. These tags are intended to last for the life of the animal. RFID’s are commonly exploited for electronically identifying animals or objects. In many submissions, the transponder unit is laden with data and attached to an animal or object which is to be recognized.
An excellent application of non-powered RFID system is revealed for identification of animals in a meat-processing place. The reason for identifying individual animals in a meat-processing plant is for safety and sterilization reasons, and to perk up the meat quality and farming methods.
An Animal ear tag typically carries an Animal Identification Number (AIN) or code for the particular animal or for its herd or flock which helps in tracing and finding the animal and to know the detailed information about the animal.
Everyone loves having pets. They offer unconditional love and give the owner a sense of relaxation from the stressful life. It is evident that owning a pet is not as easy as you think. Everything needs to be scheduled and managed form their food and comfort to managing them when they’re out of the house. However, one must always be prepared for catastrophic situations, such as those when your pet gets lost. In such situations, people generally search for them in their vicinity, but that is not always helpful.
On the other hand, using the conventional manual tracking and identification methods that have long been used for livestock management is also not recommended, although, with improvements in technology, better techniques have been introduced that are more efficient and time-saving. RFID tags have proven to be quite helpful for pet owners as well as farmers, as this microchip tags provide effective traceability, thus ensuring safety.
RFID tags have a unique number that can individually identify your pet, as this RFID tags links to the database which already consists of the information of your pet. This information is about the date of birth, breed, owner’s information and more. RFID tagging has become a significant part of modern farm management. There are many reliable RFID animal tags available in the market nowadays. It also helps the suppliers to track their livestock accurately when any cross-border and national trading of livestock takes place.
Already being used far and wide in the livestock industry, RFID has been successful in serving more than one purposes, for instance, it is becoming set up across the entire food chain for tracking. This tag is easy to use, secure and highly efficient in pet identification. These tags can be applied easily on your pet as per the directions of the manufacturer. For the security of your pet, there is a wide range of ear tags and implantable RFID glass tags available in the market that is cost-effective and can be installed on any animal.
The RFID animal tags are quite effective in saving your time, money as well as labor. If you have an RFID tag installed on your pet, with all the necessary information embedded in it, then you don’t have to worry much even if your pets get lost or stolen. These tags are quite reliable and can be one of the best solutions for tracking your pet in a hassle free manner.
RFID cards have been around for many years in various forms and mostly used in access control, security and financial applications. The technology utilized was most likely proprietary to their supplier and no open systems had existed. Most of these cards used passive RFID techniques in the frequency range of 125kHz to 135kHz. These cards were considerably thicker than most common photo ID cards, much more expensive, had limited memory space and could only be read one at a time.
Most utilization of RFID cards involved “proximity”- “contact-less” cards. These cards replaced the popular contact cards that used actual metallic contacts on its surface, or embedded ferro-magnetic wires for communications. The “proximity” card applications provided a high degree of security, however the performance range of the card was typically limited to a couple of inches, at most.
During the past few years numerous standards have emerged and are currently being adopted by the RFID transponder manufacturers. ISO 14443 for “proximity” cards and ISO 15693 for “vicinity” cards, both recommend 13.56 MHz as its carrier frequency. These standards feature a thinner card, higher memory space availability and allow numerous cards in the field to be read almost simultaneously using anti-collision, bit masking and time slot protocols.
ISO 14443 proximity cards offer a maximum range of only a few inches. It is primarily utilized for financial transactions such as automatic fare collection, bank card activity and high security applications. These applications prefer a very limited range for security.
ISO 15693 vicinity cards offer a maximum usable range of out to 28 inches from a single antenna or as much as 4 feet using multiple antenna elements and a high performance reader system.
