RFID has developed rapidly in recent years and has extended from single supply chain management applications in the past to numerous demanding applications in manufacturing, healthcare, pharmaceutical management, automotive manufacturing, asset tracking and other industries. This white paper describes the application of RFID in different environments such as high-temperature autoclaving, chemical cleaning, and automotive production lines. This article will introduce a high-performance anti-metal tag series - Xerafy's XII series of tags, this series of tags can be installed into the tag in the asset production stage, so as to play the role of automated tracking management, if the assets were stolen or lost , Find out their whereabouts through location tracking.
An advanced RFID system can effectively improve management efficiency and control costs through rational management of production processes. If assets can be enabled for RFID at the source of production, companies can better manage inventory, quality, handle recalls, and conduct product anti-counterfeiting. At present, most of the customers' requirements for RFID tags are focused on the ability to withstand harsh environments such as high temperatures and high pressures, and can be used in metal environments.
Medical device disinfectionThe instruments used by John Devlin ABI Research Institute for surgery have strict standards for disinfection. Whether or not the device has been completely disinfected is a matter of patient safety. Disinfection of surgical instruments involves several methods, of which high-temperature cleaning and sterilization are instrument sterilization methods approved by the Association of Perioperative Nurse Associations (AORN). Surgical instruments are first washed with alcohol and then placed in a steam autoclave. Nowadays, the most used are the vacuum high temperature 121 to 134 degrees Celsius disinfection 18 minutes or gravity displacement autoclaving, the temperature reached 121 degrees Celsius, sterilization for one hour . There are other ways of disinfecting, such as soaking the instrument in sodium hydroxide solution for 1 hour, rinsing and autoclaving.
The metal tray is used to place the used instruments during the operation and to disinfect the instruments after the operation. When the device is sterilized, the trays are put together in the sterilizer, so each sterilized tray is an important factor to ensure that the device will not be recontaminated by bacteria. Hospitals now track the management trays by placing two-dimensional code labels on the trays or manually recording them.
However, the two-dimensional code attached to the tray can easily be opened or even peeled off after a long period of high temperature and humidity. Moreover, the information printed on the label is also vague and unrecognizable. In this case, it is easy to make mistakes if it is manually recorded and checked.
RFID can automatically record medical trays that track incoming and outgoing disinfection equipment. The sterilization date, duration, and end time are stored in a database. Scanning labels on the handheld allows doctors and nurses to easily access this information. However, most RFID tags cannot withstand extreme heat and prolonged exposure to moisture. Even many tags mounted on metal surfaces do not have this feature. Therefore, the medical industry's need for the characteristics of RFID tags lies in the ability to withstand long periods of high temperature and humidity. The Xerafy XII series is a high-strength label with an IP rating of 68 and is highly tolerant to some typical harsh environments.

Inventory tracking and pharmacy disinfectionPierrel Ospedali is an Italian pharmaceutical company that includes intravenous products. Relevant regulations stipulate that vials need to be strictly disinfected before they can be filled with drugs. The sterilization temperature of the vial needs to be maintained at 120 degrees Celsius for 10 to 15 minutes. Therefore, the entire disinfection process must have accurate and strict control and records.
If there is a problem with any batch of drugs at the disinfection stage, the entire batch must be destroyed. If the cost of a bottle of medicine is $110, a total of 160 bottles of medicines will be produced on a batch of production lines, and the loss will be as high as $17,600.

Surgical instruments for RFID applicationsRFID technology has been proven to provide reliable and precise disinfection management of surgical trays and surgical instruments. Xerafy's Pico XII label is used here. The label is affixed to the surgical tray. The reader can automatically read and write the information of the surgical tray into and out of the disinfection equipment. The time, date and disinfection time are recorded in the label and can be used at any time. Query in the central database system.
In the department responsible for the disinfection of medical institutions, technicians use a hand-held unit to scan every tray that has an RFID tag installed and immediately know the disinfection information of the tray. This not only saves time for surgical preparation, but also provides time for patient treatment. In addition, Pico XII tags can withstand repeated high-temperature sterilization and cleaning, stable and reliable performance, extremely suitable for tracking trays in medical trays.

Since the return on investment brought about by RFID's effective management of medical trays is approximately 275,000 U.S. dollars per year, we assume here that the cost of surgical delays and overtime work per hour is 84 U.S. dollars. Therefore, RFID can indeed help hospitals improve management efficiency and improve the quality of care.

Safe medication improves disease cure ratePierrel Ospedali now uses RFID technology to track each vial feeding the sterilizing device. The vials are placed in a tray with RFID tags. The tags store the tray number, the date of sterilization, and the start of sterilization. The specific time of the end. Trays can be tracked throughout the sterilization process. In the past, the management of these important information relied on manual recording. Once an information error occurred, it could not be verified whether the product was properly sterilized, and the entire product line could only be scrapped.
The Nano XII label selected by Pierrel Ospedali Company is from Xerafy. The label can withstand the extremely high temperature of the sterilization equipment and can also be attached to metal assets for repeated sterilization and cleaning. The work that used to be managed by 2 or 3 people now requires only one staff member.
Automotive Manufacturing ProcessThe process of converting a car from a bare chassis to a complete vehicle is a rather complicated process involving many techniques and steps. Therefore, ensuring that every step of the operation is accurate is the key to producing a quality-crossing car.
If the chassis of each vehicle can be automatically tracked, the production of the entire vehicle can be effectively managed. In addition, the chassis will be painted and baked prior to entering the next production line. Nowadays, car manufacturers use two-dimensional codes that can print content as tracking devices, but it is easy to damage the labels during the production process, or the labels fall off. In particular, in the painting process, the labels are also sprayed with oil and gas that cannot be identified. Therefore, two-dimensional code labels are not practical in the automotive industry.
The automated system can seamlessly track the in-process product on the car production line, including tracking the vehicle's VIN code to ensure that each car is equipped with the correct components or is sprayed with the correct color. Therefore, when the vehicle enters the painting and baking room, the identification equipment installed on it needs to have the ability to withstand high-temperature baking, and will not affect its performance due to painting.
Xerafy XII Series TagsXerafy's XII series is the product with the best performance-to-size ratio in the UHF RFID tag products currently on the market, and its tag reading and writing performance is stable. The XII series tags are Xerafy's RFID tags developed for extreme applications. The tags have industrial-strength, high-strength properties and can withstand temperatures of up to 250 degrees Celsius. They are suitable for applications that involve high temperatures or hazardous destructive properties such as high pressure, spray paint, foundry, and Construction and so on. This series of labels is also suitable for use in areas such as high-temperature cleaning and acidic solvent cleaning. Labels will have a long life cycle.
in conclusionThe industry we mentioned above is not very much applied in the field of RFID, and these applications are also developed from continuous tests and experiments. These areas have high performance requirements for RFID tags. They not only need a stable read/write function, but also need to be able to withstand the extreme environments that the industry often encounters, such as high temperature, high pressure, humidity, and impact.
