A wireless system for monitoring portable articles includes a central alarm unit (CAU) comprising a programmed controller operatively associated with a CAU wireless communication circuit. At least one wireless sensor comprises a programmed controller operatively associated with a sensor wireless communication circuit for communicating with the CAU wireless communication circuit. The CAU is programmed to periodically determine distance between the wireless sensor and the CAU and operates in a programming mode and responsive to manual input commands to determine a normal distance of the article being monitored from the CAU. The CAU is programmed to define a first zone as the normal distance plus a first select amount and a second zone as the normal distance plus a second select amount, greater than the first select amount.

A computer implemented method of locating an asset with an RFID tracker within a secured zone includes receiving an UUID of the RFID tracker via a first RFID broadcast; determining a first signal strength of the first RFID broadcast; receiving the UUID of the RFID tracker via a second RFID broadcast; determining a second signal strength of the second RFID broadcast; receiving the UUID of the RFID tracker via a third RFID broadcast; determining a third signal strength of the third RFID broadcast; and determining a first location of the RFID tracker at a first time based on the first, second and third signal strengths. A computer implemented method of tracking an asset with an RFID tracker includes locating an asset; determining if the asset is in an allowed zone; if asset is in the allowed zone, repeating the steps of locating and determining; and if an asset is not in the allowed zone, sending a security alert.

One embodiment provides a method, including: identifying, using a tamper detection switch of an information handling device, a tampering event; determining, using a processor, contextual data associated with the tampering event; constructing, based on the determining, a signal comprising the contextual data; and broadcasting, using a radio transmission beacon, the signal. Other aspects are described and claimed.

Embodiments of the present disclosure generally relate to a wireless identification tag for association with a product to enable product self-identification and system and methods for use thereof. In one implementation, the tag may include at least one antenna tuned to receive energy transmitted at one or more frequencies within certain frequency bands. The tag may also include at least one transmitter that may be configured to send at least one identification signal. The tag may also include at least one circuit. The at least one circuit may be configured to detect whether energy is received in a certain frequency band, and to cause the at least one transmitter to operate in a mode corresponding to the certain frequency band.

Embodiments of the present disclosure generally relate to an appliance for holding electronically tagged products and for recording an association between the tagged products and the appliance, and system and methods for use thereof. In one implementation, the appliance may include a housing defining a cavity for retaining the electronically tagged products. The appliance may also include an exciter integrated with the housing and configured to trigger tags of the products to cause the tag of each product to transmit a unique tag ID. The appliance may also include a receiver for receiving transmission of each unique tag ID. The appliance may also include a communicator for outputting indications of identities of electronically tagged products retained in the cavity.

Embodiments described herein relate to an anti-theft device for commodities, and aims to provide a smart anti-theft tag for boots. The tag can effectively prevent boots from being stolen and is reliable in performance, exquisite in structure and easy to use. According to the technical solution, the smart anti-theft tag for boots comprises a tag holder provided with a circuit board, a sounder component, a coil and a battery, and a hoop assembly movably mounted on the tag holder to be tied on and connected to a heel of a boot, a bolt assembly movably located in the tag holder and used for unidirectional control of the movement of the hoop assembly, and a lock assembly movably located in the tag holder and used to lock the bolt assembly in a moving state.

An electronic article surveillance (EAS) device for monitoring items comprises an electronics housing and an elastic band. The band is attached to the housing and is used to install the EAS device onto an item. A tension monitoring apparatus monitors the band and generates a signal based on the band's state of tension. Electronics within the housing receive this signal and use it to determine the status of the EAS device, i.e. installed, armed, tampered with, etc. Loss of tension may indicate a cut band or removed EAS device. Other sensors may also generate inputs for the electronics to evaluate. These include an installation sensor to monitor contact between the housing and an item and an arming switch to arm the EAS device before installation. The EAS device may have wireless communication capabilities, and external devices may arm and disarm the device with wireless communication.

Systems and methods for operating a marker that involve receiving, by a Radio Frequency Identification (“RFID”) element of the marker, an RFID deactivation signal; and responsive to the RFID deactivation signal, supplying power to a detuner element of the marker so that the detuner element switches from a first state to a second state. The marker's resonant frequency is changed to a first value that falls outside of an Electronic Article Surveillance (“EAS”) systems operating frequency range when the detuner element switches from the first state to the second state.

A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap. The HF coil antenna can include a gap between turns for non-interfering placement of the UHF tuning loop. The EAS circuit can be deactivating upon application of a field at the resonant frequency of sufficient intensity to cause the breakdown voltage to be exceeded between a coil end and coupling area. The threshold breakdown voltage between a coil end and a coupling area can be reduced by laser ablation treatment of a conductive surface of one or both of the coil end or coupling area.
