More on Active RFID tags

by rfid11 In reply to Active RFID

<p class="MsoNormal"><font face="Times new roman" size="3">Active RFID badges are self-powered, and rely upon their internal power sources instead of RF energy from a reader. Since there is no universal standard for active RFID, there are many competing designs for active RFID systems. For example, some systems rely on making badges resonate at different frequencies. Badges could be distinguished by focusing on different frequencies. Some systems rely on badges actively transmitting all the time. Others are more reader-oriented, where the reader controls the entire transaction. The reader actively queries for the presence of certain badges. The badges, if present, could then signal their presence, either through oscillating at varying frequencies or transmitting data through transceivers. </font></p>

Active RFID and personnel accountability

by rfid11 In reply to Active RFID

<p><font size="3"><font face="Times New Roman">It?s been said that if you think safety is expensive, try an accident. Growing demand for safety in workplaces around the world has resulted in tighter regulations. Keeping track of people and equipment for safety and security can be a personnel-intensive, time-consuming undertaking that diverts attention from an organization?s primary business activities. Attempts to automate these basic, but not directly profit-generating, tasks are reflected in a wide range of products. Bar-code and card-based systems dominate the marketplace. However, RFID enjoys several advantages over bar-code systems that make it a better choice for many security and safety situations.<?xml:namespace prefix =" o" ns =" "urn:schemas-microsoft-com:office:office"" /></font></font></p>
<p><font size="3"><font face="Times New Roman">RFID comes in two flavors: passive and active.<span>  </span>Passive RFID has a reading range of ~1 ft. and is widely used in supply chain and logistics systems. The main advantage is that the tags need not be visible from the reader?s position (e.g., to avoid the loss of expensive tools, you can embed tags in the metal).</font></font></p>
<p><font size="3"><font face="Times New Roman">In an active RFID system the tags have their own power source and transmitter. An active tag can be read up to 300 ft. away, thus broadening the applicability of an RFID system. </font></font></p>
