    <h1>HRŠAK</h1>
    <h2>Vision by <a href="https://mi-hrsak.hr/o-nama/">HRŠAK</a></h2>
    <p>One of the main challenges our customer faced was the inability to locate products within the production facility in real-time. Since goods move between different halls and work zones, delays and time loss often occurred when trying to locate specific products.</p>
    <p>As we have already discussed in detail in previous blog posts, the UHF RFID system can be successfully applied across various business segments:</p>
    <ul>
      <li><strong>Manufacturing</strong>: RFID tags with antennas enable tracking of the production flow, optimization of work processes, and quick identification of bottlenecks.</li>
      <li><strong>Inventory Management</strong>: UHF RFID systems facilitate inventory tracking, automate stocktaking, and ensure timely replenishment of goods.</li>
    </ul>
    <p>To solve our customer’s problem, UHF RFID systems were installed at all doorways through which items pass. These systems continuously record the movement of goods and automatically send data to the MES (Manufacturing Execution System). Thanks to this setup, production managers and other employees can always pinpoint the exact location of each item within the facility. Additionally, the system distinguishes the direction of item movement — it detects whether an item has entered or exited a hall. This provides an accurate and up-to-date picture of the actual location of every unit, which significantly increases operational efficiency and reduces time losses in daily operations. This approach brings complete transparency to inventory management within the production facility — everything happens automatically, without the need for manual logging, enabling faster decision-making and greater control over processes.</p>

    <p>Each tag used in the system is actually dual-functional – it consists of two technologies in a single housing: UHF RFID and NFC (Near Field Communication). The UHF RFID part of the tag enables remote reading via antennas installed at the entrances and exits of the halls, while the NFC component allows manual scanning of the product using a mobile device — any smartphone or tablet that supports NFC technology. This way, users in the field, such as production or logistics employees, can simply bring the device close to the tag and immediately access detailed product information, such as:</p>
    <ul>
      <li>type of item</li>
      <li>supplier/manufacturer</li>
      <li>material it is made from</li>
      <li>weight</li>
      <li>serial number</li>
      <li>status in the production process</li>
    </ul>

    <p>This combination of automatic and manual reading enables maximum flexibility and transparency in daily operations. Whether it’s about tracking large quantities of items through the halls or checking the status of a specific product, the system provides all the necessary data – quickly, accurately, and reliably.</p>

    <p>As part of the system, ReTAG and DeTAG devices have been installed to enable advanced management of RFID tags throughout the product lifecycle in the facility. The ReTAG device allows data transfer from one RFID tag to another. This is especially useful in cases when, for example, the UHF component of an existing tag is damaged or no longer readable. On the other hand, the DeTAG device allows data to be erased from a tag when the item is no longer needed for tracking – for example, when a product has completed its usage on a machine, and the tag can then be used for another product, which reduces system costs.</p>
