RFID in Food and Beverage Package Tracking

Method for wireless information exchange between a user device and a food package holding a liquid food product using the conductive properties of the packaging material and/or the product to transform frequencies. The food package has an unshielded RFID device operating at a lower frequency. When the user device with a higher frequency RFID device is nearby, it activates the lower frequency device via electromagnetic fields. The user device transmits a request at the higher frequency which is transformed by the package's conductivity into the lower frequency for the package device to respond. This allows exchanging info between devices using different RFID frequencies leveraging the package's conductive properties.

Container with an integrated RFID module that allows RFID tagging on metal containers without interference. The container has an RFID module with a base material, metal film, and slits. The metal film on the base forms an antenna. The RFID module has electrodes connected to filter circuits. Slits separate the metal film into regions. In assembled container state, the regions capacitively connect through the container walls. This allows antenna operation despite the metal. The slit regions prevent shorting when metal film covers the container.

RFID tags for microwavable food packaging that can be safely microwaved without risk of arcing or fire. The RFID tags have shielding structures over the chip and antenna gaps that limit voltage when exposed to higher microwave frequencies. The shielding prevents arcing or sparking when the tag is accidentally microwaved with the food item. This allows the RFID tags to be securely attached to the food packaging without the risk of removal. The shielding structures have conductive shields and dielectric materials between them to prevent high voltages.

Food and beverage supply device with RFID technology to prevent errors and fraud by users. The device has an RFID reader that detects an RFID tag on a container to identify the beverage inside. An electromagnetic wave absorbing material surrounds the container to prevent reflected waves from interfering with the reader. This suppresses erroneous readings due to external signals. The absorbing material prevents reflected waves from outside the device returning to the reader, preventing false detections.

Active RF tags attached to product packaging that can track product location and status. The tags have sensors to detect packaging opening, environmental conditions, etc. They periodically transmit the product ID and status via cellular networks. This allows real-time location and condition monitoring of products throughout the supply chain.

Tracking products using wireless tags attached to packaging to monitor conditions like temperature, humidity, pressure, etc. The tags detect packaging state like open/closed and transmit ID and status to transceivers periodically. This data is sent to a computer system that identifies products based on IDs. It stores location and packaging status for products. The system can then provide insights like when products are likely to be used based on packaging state, locate products, and monitor environmental conditions.

Radio frequency identification (RFID) label with enhanced communication capabilities, security and energy efficiency. The label has separate RF modules for NFC (13.56 MHz) and UHF (900 MHz) frequencies, along with separate processing modules. It uses a power control unit to switch off the CPU during remote NFC communication when the distance exceeds a threshold. This saves power. The label also has a shared encryption module for both RFID frequencies, providing higher security. An energy harvesting circuit provides additional power. The label can use NFC or UHF frequencies based on the received signal.

Tracking and identifying food and beverage containers using smart labels to improve supply chain logistics and inventory management. The smart labels are attached to containers like bottles and cans. They have wireless communication, LED lights, displays, speakers, etc. to provide visual and audible identification. A central system can communicate with the labels to control the lights and sounds for locating specific items. The labels also store data like motion, location, temperature, etc. for tracking.

Tracking products using active radio tags attached to product packaging that can sense environmental conditions and package states. The tags send advertising packets containing unique identifiers and sensor data at intervals. Receivers listen for these packets to monitor products' locations, conditions, and histories. The tags can also have energy harvesting and detachable designs. The system enables tracking product movements, conditions, and usage across the supply chain.

RFID-based food information management system that enables tracking and tracing of food products from production to consumption to improve food safety and compliance. The system uses RFID tags on food packages that are read by RFID readers at various points in the supply chain. The tag data is sent to a server and viewed on terminals to provide real-time visibility into the food's journey. It allows monitoring food movements, inventory, and quality control. The system also provides traceability in case of recalls or contamination incidents.

Monitoring food safety and quality using smart product tags that continuously track attributes like temperature of food products. The tags transmit the data wirelessly to centralized locations for analysis and alert generation if violations occur. This allows real-time monitoring of food safety without manual checking. The system enables continuous monitoring of food quality and safety, helps prevent foodborne illnesses, reduces food waste, and provides valuable business insights.

RFID communicator between a wine bottle and a wine box to prevent counterfeiting. The communicator uses RFID tags on both the bottle and box. When the bottle is near the box, an RFID reader in the box reads the tag on the bottle and activates an alarm if the tags don't match, indicating a fake bottle. The communicator has an RFID tag on the box that the bottle reader can also read to authenticate the box.

Food enterprise logistics management and monitoring system using RFID (radio frequency identification) for efficient inventory tracking and production scheduling. RFID labels are attached to food packaging and read by RFID readers. This allows real-time inventory levels and location tracking without line of sight like barcodes. The RFID data is transmitted to the enterprise database for updating inventory and generating production schedules based on sales data.

Bottle Coating Box with RFID tag for anti-counterfeiting and enhanced product information. The box has an RFID label embedded inside and covered by a patterned paper deck. An aluminum foil antenna is attached on the outside of the box to connect the RFID label. This allows scanning the RFID tag to verify authenticity, access detailed product information like batch number and price, and track the bottle's history.

Liquid container with an RFID tag that improves recognition rate compared to attaching the tag on the lid or inside the container. The RFID tag is positioned close to one side of the vertical length of the container, preferably 1/3 of the way from the bottom. This reduces scattering/refraction of the electromagnetic waves by the liquid inside compared to attaching the tag on the lid or inside the container. It also protects the tag from moisture and damage by enclosing it between the label and the container.

A food security management system using RFID tags to track and assess food safety throughout the supply chain. The system involves embedding RFID tags in food items or packaging, along with sensors in the transportation and storage links. RFID readers scan the tags and sensors measure conditions. Data is transmitted to a central database for analysis using food safety algorithms. This provides real-time food quality monitoring and assessment. The system enables automated food tracing, safety assessment, and messaging to stakeholders like retailers, consumers, and manufacturers.
