# Tipos de Tag RFID ## Introduction to RFID Tag Types In my experience working with **tipos de tag rfid**, I've found that selecting the right tag is crucial for system performance. I recall a project where using the wrong passive tag type led to read-rate issues in a warehouse environment. My technical aptitude helped me analyze the frequency, material, and chip specifications to identify a more suitable UHF inlay, which resolved the problem. This hands-on experience solidified my view that there is no universal "best" RFID tag; the optimal choice depends entirely on the specific application, asset type, and environmental conditions. ## Main Categories of RFID Tags ### Passive RFID Tags Passive tags are the most common **tipos de tag rfid**. They have no internal power source and are activated by the reader's electromagnetic field. * **Frequency:** UHF (860-960 MHz), HF (13.56 MHz), LF (125-134 kHz) * **Read Range:** UHF: Up to 10-15 meters; HF: Up to 1 meter; LF: Up to 0.5 meters. * **Common Uses:** Inventory management, asset tracking, access control, retail item tagging. ### Active RFID Tags Active tags contain their own battery, enabling longer read ranges and additional functionalities like sensors. * **Frequency:** Typically UHF (433 MHz, 2.4 GHz) * **Read Range:** 100 meters or more. * **Common Uses:** Real-time location systems (RTLS), tracking high-value assets, vehicle tracking. ### Battery-Assisted Passive (BAP) Tags BAP tags have a small battery that powers the chip only when activated by a reader signal, offering a longer read range than passive tags. * **Frequency:** Primarily UHF. * **Read Range:** Can exceed that of standard passive UHF tags. * **Common Uses:** Supply chain visibility, specialized asset tracking. ## Technical Specifications and Parameters Providing detailed technical data is essential. Below are example specifications for a common UHF passive inlay. *Please note: These technical parameters are for reference only.
