HF RFID Tag – A Technology That Reduces Manual Scanning and Inventory-Taking Processes
HF RFID Tag is a technology that reduces the need for manual scanning and inventory-taking procedures. This results in cost savings and increased efficiency.
Printed RFID sensor tags with touch capability have high sensitivity and good functioning with metals and liquids. However, they have problems with reliability due to poor performance of the antenna.
Security
The wireless nature of RFID tags and reader systems makes them vulnerable to privacy concerns. These concerns revolve around the possibility HF RFID Tag that unauthorized parties could access information about specific individuals. This could occur through interception of the radio communications between tags and readers, unauthorized reading of tags or unauthorized access to the data stored on the tag.
Passive HF RFID tags, including Metalcraft’s standard and hard tags, offer better read range and faster data transfer than LF tags. HF tags are used in applications like credentialing, ticketing payments and building or event access management. They also work well in environments with metal and liquids.
Active UHF RFID tags, including the popular Impinj R700, have a read range that exceeds LF and HF tags. They offer faster data transmission and greater scalability than HF tags, making them well suited to logistics and asset management. They are also more resistant to eavesdropping, but scalability and performance limitations limit their use.
Regardless of what frequency is used, security concerns must be addressed at multiple levels. In addition to ensuring that the reader and antenna is properly configured, other important factors include encrypting sensitive information on tags and in back-end systems and implementing robust authentication and authorization. In medical facilities, for example, it is essential to ensure that PII stays private while allowing staff to access patient records quickly and efficiently.
Accuracy
The HF tag band has a read distance of up to 12-15 cm. It’s a good option when tracking items with a lot of metal surfaces or liquids, such as beer kegs or automobiles.
This frequency range has been around since 1979 and is the most mature RFID solution. It uses near field magnetic flux to power and communicate with the tag. The most common HF standards are ISO/IEC 14443, ECMA-340 and ISO/IEC 18092 (NFC for NFC technology), ISO/IEC 15693 (for MIFARE), and JIS X 6319-4 for FeliCa.
HF tags typically have low manufacturing costs, high memory capacities and good functioning with liquids and metal materials (but less tolerance for interference from certain materials). Typical applications include access control, ticketing, item-level logistics, retail, library and bookshop management, CD & DVD tagging and pharmaceutical items.
The tags can be mechanically mounted using cable ties, key rings or adhesive discs. Some can even be embedded under the skin to track patient medical records in hospitals. They are also well suited for tracking assets in the factory, warehouse or retail store. By utilizing RFID, businesses can instantly check in shipments and reduce cycle counts, and auto-reorder products at safety stock levels before they run out. This improves stock accuracy in stores, which can increase sales and lower inventory costs. These benefits help businesses reduce stock outs, which is a common problem in retail and distribution environments.
Efficiency
The HF RFID tag is highly efficient in the way it uses energy to communicate. It uses magnetic flux to power and transmit its unique ID number to an RFID reader that decodes the signal, recording it in a database. This eliminates manual scanning and inventory-taking processes, significantly cutting down on labor costs and time. It also improves accuracy, as human error is eliminated, and the technology can be used at a much faster rate.
HF systems operate in the 3 MHz to 30 MHz range and provide reading distances of 10 cm to 1 m (3 ft). They are commonly used for electronic ticketing, mifare desfire ev3 payments, or user-experience applications. They are compatible with the ISO 15693 standard for RFID tags, the ECMA-340 and ISO/IEC 18092 standards for Near Field Communication (NFC) technology, and the ISO/IEC 14443A and ISO/IEC 14443 B standards for MIFARE and other proximity card technologies.
HF tag interrogators can detect the electromagnetic fields of multiple tags simultaneously, which makes them ideal for use in retail inventory tracking, building security, and door access control. They can also be combined with sensors for real-time location systems (RTLS) to track anything from wheelchairs in a hospital to cargo containers at a shipping dock. Depending on the application, HF tags can be passive or active. Passive tags do not emit a signal until they are “woken up” by a reader, conserving battery life. Active tags, on the other hand, require a battery and transmitter and may use advanced features like anti-collision.
Sustainability
HF RFID tags can be applied once and used for the life of an item, making them more sustainable than barcodes or printed labels that require frequent replacement. Recurring costs in an RFID system can include the cost of printer ribbons, batteries or software licenses and should be factored into an ROI calculation.
Unlike LF tags, which only read when a handheld reader comes close to them, HF tags can transmit and be read from distances of up to several feet, meaning less manual labor. This makes them ideal for applications such as produce management, where readers can be kept in a truck or cart and read entire pallets of goods at a time.
In addition, HF RFID can function through a variety of materials and environments. The technology can be used as a reliable verification system for access control and security purposes, providing a discreet way to identify authorized personnel within a facility. It can also track inventory and supply chain processes, ensuring that businesses are always in the know and can anticipate stock-outs.
HF ISO-18000-3 Mode 2 RFID tags are popular in the market because they work well with liquids and metals, as well as on items with medium to high water content. They also have anti-collision capabilities to enable them to operate with multiple tags in the same area.
