The system and techniques disclose herein describe a radio-frequency identification (RFID) capacitance liquid measurement and tag (RCLMT) system for detecting a volume of liquid in a container (liquid level detection), for example an amount of wine inside of a wine bottle. The RCLMT system includes a RFID chip, flexible printed circuit board (PCB), capacitive strips, and adhesive which implements a RFID tag-based sensor that advantageously uses low power and has low cost. Further, a user platform, including the RCLMT system and computer software applications (apps) and a backend system (e.g., cloud service) is described herein. The RCLMT system acts as a passive liquid level detection sensor, which enables the amount of a liquid beverage, such as alcohol, that is inside of a container to be automatically and accurately ascertained.

The use of reusable containers is coupled to merchant loyalty programs. Use of a reusable container by a customer in a transaction with a merchant earns benefits in the merchant's loyalty program to incentivize use of the reusable container. Each reusable container incorporates unique identity information. The unique identity information is associated with a customer. Used reusable containers can be exchanged for reprocessed or new reusable containers, and customer associations updated when containers are exchanged. Merchants associated with different corporate entities can participate together where reusable containers can be exchanged between different corporate entities.

A contactlessly readable tag includes a metal pattern layer, a conductive layer, and at least one intermediate layer. The intermediate layer has a relative permittivity of 0 or more and 2.5 or less and is provided between the metal pattern layer and the conductive layer. The metal pattern layer includes a metal part whose arrangement pattern corresponds to identification information. The identification information is configured to be identified based on information on an electromagnetic wave that is reflected by the contactlessly readable tag in response to irradiation of the contactlessly readable tag with an electromagnetic wave. The metal pattern layer is provided closer to a reading surface of the contactlessly readable tag than at least one of the intermediate layer.

Methods, kits, and systems using machine-readable labels are disclosed to assist in communications between the material provider and the end-user of a graphic film product, especially when the end-user does not acquire the graphic film product directly from the material, where such communications may relate to the warranty for the graphic film product.

A dual security tag including an RFID component and an electronic article surveillance (EAS) component, respectively disposed on opposite sides of a PET carrier substrate, is provided. The RFID component may include one or more ultra-high frequency antennae, such as a near field loop antenna and a far field dipole antenna, and an integrated circuit (IC) chip. The EAS component may be provided as an RF device, an acoustic-magnetic (AM) device, a low power Bluetooth (BLE) device, or other suitable device. The security tag may also include a facesheet affixed to the RFID component, a release liner layer affixed to the EAS device, and one or more intermediary films or protective layers. A method for manufacturing a dual security tag is also described.

The present invention provides a method and system for verifying and tracking identification information. In an embodiment of the invention, a system for delivering security solutions is provided that includes at least one of the following: a radio frequency (RF) identification device, an identification mechanism (e.g., a card, sticker), and an RF reader.

A dual band transponder comprises a carrier substrate having at least one planar substrate layer. An ultra-high frequency loop antenna is mounted on a first surface of one of the planar substrate layers of the carrier substrate. A high frequency loop antenna is mounted on two opposite surfaces of one of the planar substrate layers of the carrier substrate. The ultra-high frequency loop antenna encloses the high frequency loop antenna in a plane parallel to the at least one planar substrate layer entirely. A textile label includes a textile label substrate and a corresponding dual band transponder mounted onto the textile label substrate.

Application and associated methods relate to facilitating verification of authenticity of a product instance. Such verification of authenticity is facilitated by a verification transceiver configured to be affixed to a product instance. The verification transceiver includes an engagement fixture configured to affix the verification transceiver to a product instance. The verification transceiver includes a receiver configured to receive a query signal from a proximate mobile device. The verification transceiver includes a transmitter configured to transmit a current encoded signal indicative of the product instance in response to receiving the query signal. The verification transceiver also includes a verification-code sequencer configured to advance the current encoded signal to a next encoded signal in a sequence of encoded signals, each of the sequence indicative of the product instance, current encoded signal advanced to be transmitted in response to a next received query signal.

Label constructions comprise a first section and a second section that are laminate constructions of a card stock top surface that may include printed indicia, an adhesive layer disposed underneath the card stock, and a removable liner adhered to the adhesive layer and common to the first and second sections. The first section includes an RFID device. The first section may be configured once removed from the liner to fold on itself to form an RFID tag, or to form an RFID adhesive label. The second section once separately removed from the liner forms an adhesive label. The construction first and second sections are positioned adjacent one another and are formed during the same manufacturing process for purposes of manufacturing efficiency. The first and second sections may be treated to facilitate separate removal from the liner to provide labeling flexibility.

Example embodiments relate to radio-frequency identification (RFID) tags for liquid monitoring. An example RFID tag includes an antenna configured to communicate with an RFID reader. The antenna includes a radiating plane. The antenna also includes a ground plane. The RFID tag is attachable to a container. A reactance associated with the antenna is modifiable based on a temperature and a volume of a liquid within the container and adjacent to the ground plane. The RFID tag also includes an integrated circuit that includes a memory. The integrated circuit is configured to modulate the antenna in response to an RFID signal from the RFID reader based on the reactance associated with the antenna.
