Types of RFID

Key Takeaways: RFID and NFC are different technologies within the broader RFID family. While RFID is a method for item identification using radio waves, NFC is a specialized subset of RFID that operates at the 13.56 MHz frequency and enables secure peer-to-peer data exchange. NFC devices can act as both readers and tags, making them suitable for contactless payments and sharing information between devices through close proximity.

Key Takeaways: Passive RFID systems use tags powered by electromagnetic energy from an RFID reader. They are cost-effective for applications like access control, file tracking, and supply chain management. Active RFID systems use battery-powered tags that continuously broadcast signals, enabling accurate real-time asset tracking. Active tags have a longer read range but are more expensive.

Key Takeaways: The main difference between Active UHF RFID technology and GPS lies in their functionality and purpose. Active UHF RFID technology utilizes an internal power source and operates on the UHF band, allowing for long read ranges and applications. On the other hand, GPS is a satellite-based system used for locating and tracking GPS-enabled devices by calculating their distance from multiple satellites to determine precise location coordinates.

Key Takeaways: These tags are a middle-ground option between passive and active RFID tags. They incorporate an internal battery that powers the tag when it receives a signal from an RFID reader, allowing for an extended read range of up to 100 meters and the integration of sensor monitors. BAP tags find applications in industries such as logistics and manufacturing, and they can improve asset management and streamline processes through their compatibility with Gen2 passive RFID hardware.

Key Takeaways: Active sensor monitoring RFID tags include transponders and beacons, with transponders responding when interrogated by an RFID reader and beacons consistently sending information at intervals. Passive sensor monitoring tags use RF energy to power the sensors and detect temperature, humidity, and moisture. BAP sensor monitoring RFID tags have greater range than passive tags, requiring interrogation by a reader and offering the option to send real-time sensor data or store and transmit collected data when requested.

Key Takeaways: iBeacon technology, developed by Apple, is a Bluetooth standard that enables mobile applications to interact with beaconing hardware in indoor environments. It consists of a beacon for transmitting signals and a smartphone or electronic device for receiving, processing, and responding to those signals. The main uses of iBeacon technology include tracking customers within indoor spaces and triggering actions on their smartphones or tablets based on their location within the environment.

Key Takeaways: The IoT requires objects to be augmented with Auto-ID technology, such as RFID tags, to enable unique identification and wireless communication of information, while embedding sensors allows for data monitoring. Real-time data reporting enabled by sensors, RFID tags, and readers in the supply chain allows for improved decision-making, increased efficiency, waste reduction, and enhanced traceability. In everyday life, IoT applications can improve well-being and save time and money by automating tasks such as grocery list management and promoting prescription adherence in healthcare through smart devices and real-time information updates.

Key Takeaways: Real-Time Location Systems refers to any system that accurately determines an item or person's location. RTLS is not limited to a particular system or technology; instead, it represents a goal that can be achieved using various asset tracking and management systems. The timing of asset tracking is a crucial element in RTLS, and the data obtained can be utilized in diverse ways depending on the specific application. RTLS consists of components such as transponders (tags), receivers, and software, and employs technologies like Bluetooth Low Energy, GPS, RFID, ultrasound, and Wi-Fi to achieve location tracking.

Key Takeaways: Both Bluetooth classic and BLE technology standards utilize RF signals to communicate and exchange identification information, placing them in the category of radio frequency identification (RFID). These technologies are grouped into three categories: Bluetooth Classic Devices, Bluetooth Smart Ready Devices/Bluetooth High Speed, and Bluetooth Smart/Bluetooth Low Energy/BLE. Both Bluetooth classic and BLE devices communicate through RF waves at the 2.4 GHz frequency, typically with a battery, making them active RFID technologies. In traditional RFID use cases, BLE is employed by attaching BLE tags to items or assets and utilizing Broadcast or Mesh Network topology to expand the communication range.
