Asset tags, also referred to as asset lables, identify any number of physical assets, from equipment and tools to racks and machines. Asset tags are used to identify physical assets and feature serial numbers or barcodes for identification purposes. Most asset labels have adhesive backing and are made of anodized aluminum, laminated polyester, vinyl, or foil. The more durable the asset label, the easier it is for the organization to conduct asset identification, tagging, and tracking.
RFID reading distance depends on several factors including:
* Size of the tag’s antenna
* Tag chip
* Tags orientation in the reader field
* Strength of the reader field
* Environmental factors like metal, water or other material around the tag
* LF, HF and UHF near-field tags typically have a reading distance of ~1 ft (30 cm).
* UHF far-field tags typically have a reading distance of several m/ft but are strongly dependent on the environment.
* NFC Tags (HF) are designed for near-field communication with a smartphone or similar device and typically have a reading distance of ~1 in (2 cm).

3. Information Retrieval and Integration
Tag identification provides the most critical information extraction function for UHF RFID applications. However, even though the storable information capacity of UHF RFID has been greatly improved compared to other identification technologies, its storage information is comparable to that of From the perspective of the entire Internet, it is still extremely limited. Therefore, based on the limited keyword information of the tag, UHF RFID tags become the window to access the vast digital media world by extracting information on the Internet side, and provide more dimensional perception through this information retrieval and integration. Experience and achieve fast and efficient information management.
The process of information collection is realized by UHF RFID technology. The whole working process of the UHF RFID system is shown in the figure below. The UHF RFID reader continuously transmits the reference signal carrying energy to the surrounding, and the energy is super The high-frequency RFID tag immediately returns the data carried by the UHF RFID reader in a reflective manner by modulating the circuit signal, and the UHF RFID reader decodes the received data and transmits it to the host for processing.

But more importantly, we work closely with our clients in various industries throughout the world and have been a major provider of RFID in harsh environments for many years. Through our experience we know what works, and what doesn’t. Even as opportunities are increasing, compliance requirements, capital investments and global competition continue to pressure your margins, processes must be leaner.
Recently, we published a customer success story on how digital automation using RFID is transforming the business of extraction which is one example of our capabilities and how RFID technology can help you manage your assets from beginning to end. Read the Success Story now.
While every RFID solution is unique, and involves specific requirements, here are a few highlights of the best practices for using RFID tags in the “Top 10” applications in harsh-environments …
1. RFID for Yard Management in Rugged Environments
OPP4215 RFID tags can help you identify and locate 100,000 or more assets — even across an industrial yard spanning several square miles — so you can more efficiently manage your operations, inventory tracking, forecasting, and compliance. But to count the many, or locate the one, make sure your RFID tags meet the specific demands of your environment: whether you’re dealing with sub-zero temperatures or sweltering heat, exposure to seawater or extreme sunlight, challenging terrain or physical obstructions, or other factors.
2. RFID for High-Impact Environments
We thoroughly test our RFID tags in real-world situations and extreme conditions. So yes, we’ve made the “sledgehammer proof” RFID tag (or as our engineers like to say, a tag that has been rigorously compression-, torque-, and crush-tested). As a best practice, make sure your RFID tags are tough enough to withstand whatever the weather — or drilling pipes, shipping containers, operators or other heavy objects — may throw at them.
3. RFID in Explosive Environments
When munitions or other kinds of explosives are involved, make sure your RFID solutions are certified (ATEX, C1D1, C1D2, and IECEx). And make sure you can specifically customize your passive RFID or active RFID tags with static-discharge coatings for example, to meet (or in this case, very much exceed) your specific safety requirements. And when it comes to using RFID tags around explosives, don’t be shy about asking for certification, compliance materials, and test data.
4. RFID for High-Temperature Environments
We’ve done a lot of testing with our high-temperature RFID tags: freezing them, then heating them up to 280°C, and then repeating the process over and over again). But every RFID application is unique, like applying RIFD tags on the automotive assembly line while the paint is baked on. So make sure that your high-temperature tags (and their specific shape, size, coatings and adhesives) have been thoroughly tested for the high temperatures and extreme heat involved in your particular application.
5. RFID Tags for Cylinders, Pipes, and Pipelines
These applications often involve harsh environments, high-temperatures or explosive environments, with their own unique challenges, such as the active RFID applications used by utility providers and our other clients in the energy industry. For the utmost safety and reliability in pipes, casings, drill collars, underground lines or similar equipment, make sure your RFID tags fit — and can withstand the heat, friction, and other harsh elements involved.
6. High-Memory RFID
Sometimes an RFID tag must do more than just identify or locate an asset. So when using RFID tags to encode more data, make sure you choose the right kind of high-memory RFID tag — with the right amount of memory, to cost-effectively store the asset data you need — whether you’re using RFID tags for IT asset management, military transport vehicles, retail supply chain management, or other applications, like transforming paper labeled boxes into smart containers.
7. RFID in “Noisy” High-Interference Environments
Wi-Fi, hand-held radios — even the microwave in the breakroom — all of these things can interfere with RFID applications, whether active RFID tags or passive RFID tags are involved. That’s why it’s important to thoroughly test your RFID tags in real-world situations: across the entire industrial or construction yard, or throughout a sprawling 2.4 million square-foot manufacturing facility, and especially in areas with excessive signal noise and signal interference — even at lunch time.
8. RFID in Environments with Chemical Exposure
Getting the right kind of RFID tag, with the right materials, coatings and adhesives is critical for deploying tags in environments involving chemical exposure. And it’s critical that your RFID tags can withstand individual chemicals — but also the potential chemical combinations — whether just a splash, or repeated exposures, or submersion, again and again. And when using RFID tags for instruments at medical facilities, for example, it’s also critical to consider contamination factors.
9. RFID for Anti-Counterfeit and Anti-Tampering
Sometimes harsh environments have nothing to do with snow, nor rain, nor heat. The retail, manufacturing, logistics, and transport industries are harsh enough — especially when it comes to verifying that your goods and materials are authentic — and preventing them from being tampered with, physically or digitally. When dealing with counterfeiting and tampering, it’s best that your RFID tags can prevent or identify tampering with the tag itself — and also protect the tag’s data with proper encryption, no matter where your goods, supplies, and merchandise may be in service or in the supply chain.
10. RFID Infrastructure and Putting It All Together
So when it comes to the big picture, and using RFID in harsh environments, it’s more than just getting the right kind of tag on the right frequencies. Make sure your RFID tags have been thoroughly tested to meet your specific conditions. And don’t be satisfied with an RFID tag that can’t stand up to your worst-case scenarios, especially in harsh environments. And even the best passive RFID or active RFID tags won’t matter, if you don’t have the right RFID tag readers — whether manual, automatic, or mounted on a drone (yeah, we’ve done that). Ultimately, you want a proven RFID strategy — with the right RFID tags and labels, tag readers, software, infrastructure, and RFID technology all in synch — especially when deploying an RFID technology in harsh environments.
The use of RFID in car are access control, vehicle identification, vehicle tracking.
Access Control – The ability to allow or deny access based on a vehicle having a specific RFID tag is a valuable way to provide a building or parking lot an enhanced level of security. These systems keep out unauthorized vehicles that would otherwise take up space and deters individuals from entering a secure building or lot. Thousands of RFID vehicle access control applications are operative in apartment/housing complexes, secure parking lots, construction yards, etc.
Vehicle Identification – The ability to identify a vehicle and access information about it by reading its RFID tag is a beneficial for companies like car rental agencies, car dealerships, and even car wash facilities. With the addition of software, these companies can pull up car records or purchases by just reading the car’s unique RFID tag. Rental companies and dealerships could have several cars on the lot that are nearly identical, so the unique RFID tag provides them with vehicle identification without trying to find and compare multiple VINs. Car washes (and other companies using car servicing as a business model) can use RFID to uniquely identify cars to enhance loyalty programs and automate transactions. Additionally, states and localities use RFID systems to automate tolling charges and keep traffic flowing more smoothly for those participating in the program.
Vehicle Tracking – Tracking a vehicle while it is traveling hundreds or thousands of miles is not a capability of UHF RFID; but, if checkpoints are set up along the route, the location of the vehicle can be estimated based on when it passes each one. This is being done throughout the nation at large truck weigh stations along major interstates. When 18-wheelers are weighed, their RFID tags are read to pinpoint location and can also be used to document the journey. For companies or persons interested in tracking vehicles in real-time and without setting up expensive infrastructure, vehicle GPS tags are a better solution.
RFID tags are with various selection and prices. You can visit RFID Tags and RFID to get more information from http://www.oppiot.com .
