Active RFID tagsActive RFID tags are powered by a built-in battery. Different labels use different numbers and shapes of batteries.Advantages: long working distance, the distance between active RFID tag and RFID reader can reach tens of meters, even hundreds of meters.Disadvantages: large size and high cost, use time is limited by battery life.Passive RFID tagsPassive RFID tags do not contain batteries, and their power source comes from the RFID reader. When the passive RFID tag approaches the RFID reader, the antenna of the passive RFID tag converts the received electromagnetic wave energy into electric energy, activates the chip in the RFID tag, and sends the information in the RFID chip.Advantages: small size, light weight, low cost, long life, can be made into different shapes such as sheet or hanging buckle, suitable for different environments.Disadvantages: Since there is no internal power supply, the distance between the passive RFID tag and the RFID reader is limited, usually within a few meters, and a higher-power RFID reader is generally required.Working PrincipleCompared Use cases and scopeIs your goal to track inventory in a specific room? If so, passive RFID may be your ideal choice. However, if you need to physically monitor the physical location of tagged objects throughout the building, active RFID will be your best choice. This boils down to scalability and functionality. Passive readers can only read tags about 1 to 5 meters away-so expanding a system that can be used to actually track the location of items will require a large number of readers.On the other hand, active RFID systems are easy to expand because the reader can detect tags beyond 100 feet. This means that in some cases, you can cover 10,000 square feet with just one reader and a few reference points. For example, calculate their position relative to a reference point and send these data to nearby readers. The reader then sends the location data to the gateway, which then sends it to the application. The application obtains data and provides users with an estimated location of each tagged asset.Label costIf the cost of the tag is the main driver of your decision, then passive RFID will win every time.Battery LifePassive RFID tags are simple and do not require batteries-which means they can be used almost permanently, which is an important part of their appeal. On the other hand, the service life of active RFID tags is usually between three to five years, and some can last as long as 10 years. Although passive is the clear winner in terms of tag life, it is worth noting that active RFID tags have a longer battery life than some other RTLS technologies (such as ultra-wideband and WiFi).Environmental restrictionsPassive tags are easier to completely seal and are more suitable for harsher environments. Since active tags require batteries, it is more difficult to reinforce them. Keep in mind that active tags also cannot always withstand the autoclaving process-so if...

Nowadays, RFID solutions have been increasingly used in logistics, healthcare, retail, automation and other fields. Since there are thousands of RFID tag configurations, choosing the right RFID tag is a very important but challenging problem. The primary consideration for choosing the right RFID tag1. Tag frequencyEach RFID system operates in one of the three frequency bands of the electromagnetic spectrum: low frequency (LF), high frequency (HF) or ultra high frequency (UHF). Generally, as the operating frequency increases, the data processing speed will also increase, and the reading range will also increase, that is, the distance between the active reader and the passive tag it reads will also increase. However, increasing the frequency tends to reduce the ability of radio wavelengths to penetrate certain materials.Low frequencyFrom 30 kHz to 300 kHz. Low frequency tags usually operate at 125 kHz or 134 kHz. The main disadvantage of low-frequency tags is that they must be read from within three feet and the data transmission speed is very slow. But they are more immune to interference than UHF tags.High frequency HFIt is generally considered that this is from 3 MHz to 30 MHz. HF RFID tags usually operate at 13.56 MHz. They can be read from a distance of less than 3 feet and can transmit data faster than low-frequency tags. But they consume more power than low-frequency tags.UHF, UHFCountries choose different frequency bands, usually ETSI 865.6-867.6MHz and FCC 928-928MHz these two standards. If the reader transmits on the 902-928 MHz frequency band and tries to read a tag tuned to the 865-868 MHz frequency band, the tag can also recognize hundreds of UHF tags simultaneously.2. Mounting surfaceEach RFID tag is designed to be applied to a specific material or subset of materials. RFID tags usually work well on materials such as plastic, wood or cardboard, but only certain tags can work well on more complex materials such as metal or glass. Tags that can be mounted on metal or glass are usually more expensive than typical RFID tags or inlays3. Environmental conditionsThe environmental conditions that the label may encounter during its life cycle are the main considerations for label selection. The main items are temperature, water, pressure, chemicals, steam, etc.4. Storage capacityIt all depends on the use of RFID. Sometimes, it is only necessary to identify the product by a unique identification number that will be recognized by the database. But sometimes the memory of the chip must be larger and contain other information. For example, this is necessary for isolated areas, operators who cannot access the database, tags with large storage capacity will be able to make more detailed records.5. Reading distanceThe required reading distance will determine the frequency selection, LF, HF and UHF. If the reading distance is short (cm or inches), all three types are fine; if the average distance (up to 50 cm / 20 inches), HF or UHF can be used. But f...

1. Normal labels do not performed well on metal surface and are even unreadable. Our RFID On-metal Labels has good performance on metal2. Our RFID anti-metal labels are thin,soft and flexible, so they can be used on curved surface than hard tags.3. It can be printed and coded by RFID printer at the same time. So it’s easy to make visualization and programing customization,such as logo, serial number, barcode, QRcode etc4. They keep a long reading distance on containers filled with liquids (such as wine, beverage and cosmetic bottles)5. Lower cost compared with those hard tags 

For those who do not know the situation, installing or embedding RFID tags on metal is a tricky problem, so it is wise for those who do not know the situation. The metal surface reflects the energy emitted by the RFID reader and interferes with the RFID tag antenna, which means that the tag cannot receive power and transmit information. However, certain RFID tags will work around metal surfaces. RFID company has patented technology that allows RFID to work normally when attached to metal surfaces or even embedded in metal products. As long as you choose the right RFID device according to your own situation and application, you don't need to worry about metal interference.Which industries are using metal mounting tags?RFID on metal tags is ideal for asset and tool tracking in medical equipment in healthcare, IT (information technology), laptops and servers, industrial manufacturing, oil and gas pipelines, vehicle tracking and identification, and many other vertical industries. With the latest development of RFID technology, the possible application range of metal-mounted RFID tags has become wider and wider.What kind of conditions and environment are metal labels suitable for?Because so many metal surfaces are exposed to harsh conditions, many RFID metal tags are specially designed and configured to withstand harsh conditions. These rugged RFID tags are usually encapsulated in a hard shell, which can withstand hard impacts, moisture exposure and extreme temperatures.How to paste these Read on Metal labels on different metal surfaces?Since the use of metal-mounted RFID tags varies greatly between different industries, manufacturers provide tags that suit your application environment. Each type of metal tag has a unique fixing method.1. Hard labelHard labels provide you with a wide range of options to attach labels to metal surfaces, such as using magnetic nails, popular rivets and industrial adhesives.2. Embedded labelOther tags can be embedded in metal objects before and after manufacturing, and then sealed with epoxy to provide additional protection. This application method and the small size of the tag make it popular in healthcare and other industries that track small tools.3. Printable and flexible labelsIf you need a printable RFID label that can be used with metal, some manufacturers provide labels that are directly attached to the metal surface with adhesive. Some of these labels have a paper surface, so you can print private logos, product information or scan barcodes directly on the labels. If you need paper-based RFID tags that can still withstand harsh environments, Metal Tag provides flexible RFID tags that can be adhered to curved surfaces.

Regarding to RFID projects, you may encounter the following problems:1. Normal paper label cannot be used for liquids and metals2. If you use paper labels, they look ugly and easy to fall off3.If it is a metal hard label, it is always thick and cannot be bent or printed, etc.Now Sun Rise Rfid provides UHF RFID anti-metal and liquid tags that can help you solve these problems, which can be used for liquid bottles, metal assets, and non-metal items. They have good performance on all different items.Since they are soft materials, they may bend instead of curved surfaces. Double-sided, they are very thin, so they can be printed and encoded by an RFID printer at the same timeA label for liquid bottles, metal assets, and non-metal items makes your RFID project easy.

The system may use many RFID frequencies or RFID bands.The frequency used by an RFID system determines many characteristics of its operating mode. Therefore, determining the correct RFID frequency band is an important early decision in the development process.RFID frequency band allocation There are four different RFID frequency bands or RFID frequencies in the world. They are placed in different areas of the radio spectrum, which enables RFID to select the frequency that can obtain the correct system parameters.RFID FREQUENCY BAND / SPECTRUM ALLOCATIONSRFID FREQUENCYBANDFREQUENCY BANDDESCRIPTIONTYPICAL RANGETYPICAL RFID APPLICATIONS125-134.2 kHz and 140-148.5 kHzLow frequencyUp to ~ 1/2 metreThese frequencies can be used globally without a license.

NFC Standards and NFC ForumThe NFC standard covers communication protocols and data exchange formats, and is based on existing RFID standards, including ISO/IEC 14443 and FeliCa (common in Japan). These standards include those defined by ISO/IEC 18092 [7] and the NFC Forum.The NFC Forum was established in 2004 by Sony, Nokia and Philips to implement strict standards that manufacturers must meet when designing NFC-compatible devices. This ensures the security of NFC and keeps it easy to use in different versions of the technology. Compatibility is the key to the growth of NFC as a popular payment and data communication method. It must be able to communicate with other wireless technologies and be able to interact with different types of NFC transmissions.3. How does NFC work?NFC uses magnetic induction to work: the reader emits a small current, which generates a magnetic field, which bridges the physical space between devices. This field is received by a similar coil in the client device. In this field, the field is converted into electrical pulses to transfer data, such as identification number status information or any other information. The so-called "passive" NFC tag uses the energy of the reader to encode its response, while the "active" or "peer" tag has its own power source and uses its own electromagnetic field to respond to the readerTo ensure security, NFC usually establishes a secure channel and uses encryption when sending sensitive information (such as credit card numbers). Users can further protect their private data by keeping antivirus software on the smartphone and adding a password to the phone to prevent thieves from using it if the smartphone is lost or stolen.

According to reports, Michelin will implant radio frequency identification (RFID) chips in all of its car tires by 2023.RFID chips will help improve driving safety and provide predictive maintenance services.RFID can track the entire life cycle of tires and make a significant contribution to "predictive maintenance services". It can also be used to improve driving safety and enable advanced driver assistance systems (such as ESP) to be adjusted to specific tire characteristics. It also provides support for timely and accurate tire replacement, provides accurate tire identification and data for dealers and repair shops, reduces assembly errors, and helps control inventory.This technology uses up to 15 million chips per year. It can be used to increase the recycling rate of used tires, verify recycling and improve the efficiency of energy recovery projects. As the links between cars become closer, Michelin is also working with automakers to develop algorithms to pave the way for further development.Michael Ewert, vice president of global sales for Michelin's original equipment, said: "We are currently working with car manufacturers to develop algorithms. Because RFID technology can ensure such accurate tire identification, it is conceivable that drivers will see the status next to the tire fuel gauge in the future. Display. This status monitoring will become more and more important, especially for increasingly automated vehicles."
