Described herein are techniques related to near field coupling and wireless power transfers. For example, a coil antenna configuration is the same in all portable devices; however, when the portable devices are arranged in back to back position with one another, the coil antenna configuration defines a dissymmetric and antenna configuration.

A reading apparatus includes a communication unit, a scanner, and a processor. The communication unit communicates with a wireless tag provided on paper. The scanner scans the paper. The processor acquires data from the wireless tag through the communication unit, acquires an image from the paper by using the scanner, and generates a file in which the data is embedded in the image as hidden characters.

A near-field communication device includes: a processing module and a first antenna arranged in a first near-field communication area and connected to the processing module; a first presence detector arranged in the first area; a second antenna arranged in a second near-field communication area, the first antenna and the second antenna being electrically in series and forming a circuit of antennae; a second presence detector arranged in the second area; and a control circuit designed to place the circuit of antennae into at least two different operating modes: a) a first mode, termed ‘functional mode’, in which the circuit of antennae allows near-field communication, and b) a second mode, termed ‘dysfunctional mode’, in which the circuit of antennae does not allow near-field communication.

A multifunctional portable data card and a data transmission method are provided. The data card includes a main control module, a gear selection module, a data transmission module, an interface module and a storage module. The main control module detects a gear selection signal generated by the gear selection module, and sends a corresponding operation command to the data transmission module according to a working mode corresponding to the gear selection signal; the data transmission module performs data transmission in the data transmission mode or the OTG data processing mode after receiving the operation command; the interface module provides a port for interaction between the multifunctional portable data card and an external device; and the data card further includes the storage module.

A near field communication device included in a secure transaction card provides an addition and/or transitional communication link for communicating secure transaction information. The near field communication device may be selectively engaged or disengaged and, when engaged, either active or passive modes of operation of the near field communication device can be selected. in the active mode, secure transaction information is transmitted upon establishment of a communication link with a complementary near field communication device. In the passive mode, secure transaction information is transmitted upon interrogation from a complementary near field communication device. Secure transaction information is generated and stored for transmission in a memory and at least a portion of the memory is erased or nulled upon transmission or upon expiration of a selected period of time.

There is provided a method including generating an initial token being associated with a given context, and sending the initial token to a destination device. The method also includes receiving a scanned token generated by a mobile device scanning an output of the destination device. The output may be generated based on the initial token. In addition, the method includes authenticating the scanned token by comparing the scanned token to the initial token. Furthermore, the method includes generating a productivity indicator based on the scanned token, and outputting the productivity indicator.

Example embodiments of the present disclosure include a system comprising a computer-readable storage medium storing at least one program and a computer-implemented method for providing an offer based on a level of buying intent of an individual. Consistent with some embodiments, the method may include monitoring an amount of time an individual wears a particular garment while in a fitting room of a retail store, and determining an interest level of the individual in purchasing the garment based on the amount of time the individual wears the garment. The method may further include generating and provisioning an offer to the individual based on the determined level of intent.

Provided herein is a system involving the utilization of a low-power device that is programmed to capture data from a source, whether from a sensor or other type of data generating component, with the data capture and/or further data transfer set within a specific time period and further data storage platform having programmed storage compartments uniformly set to meet the exact date and time for which the data capture and/or transfer was initially undertaken. Having a known value of storage capacity for each timed data packet in this manner, the ability to ensure veracity of the transferred data is provided since any result that does not meet the time frame and thus the storage capacity set from the programmed platform itself will result in a quarantine of any problematic data packet, thus allowing for filtering and review of any unexpected data captured and transferred in such a manner.

Disclosed is a method for determining a type of an object arranged in a radio frequency, RF, field transmitted by an NFC reader device. This method involves analyzing the oscillatory behavior in the NFC reader device, after the RF field transmitted by the reader has been switched off, using a decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components. The method involves predetermining the decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components, e.g. weighted oscillation components, wherein each one of said M superimposed components is defined by a predetermined superimposition function, which in turn is determined by an associated set of characteristic parameters, and storing, e.g. in a database that is accessible for the P&E unit, an indication of the decomposition scheme and the M predetermined superimposition functions.

In one embodiment a UHF RFID reader is adapted to operate in either a reader mode or in a tag emulation mode, wherein in the reader mode the UHF RFID reader communicates with at least one RFID tag to access the at least one tag's memory contents and in the tag emulation mode the UHF RFID reader communicates with at least one other UHF RFID reader to share memory content with the at least one other UHF RFID reader. Furthermore, an RFID network and a method for communication in an RFID network are described.
