Described is a method for guiding a user for positioning a first RFID-enabled device relative to a second RFID-enabled device for allowing a robust RFID communication between the two RFID-enabled devices. The method includes placing the first RFID-enabled device to a first position relative to the second RFID-enabled device; receiving, by the first RFID-enabled device, when being located at the first position, a first RFID signal transmitted by the second RFID-enabled device; measuring, by the first RFID-enabled device, a first signal strength of the first RFID signal; placing the first RFID-enabled device to a second position relative to the second RFID-enabled device; receiving, by the first RFID-enabled device, when being located at the second position, a second RFID signal transmitted by the second RFID-enabled device; measuring, by the first RFID-enabled device, a second signal strength of the first RFID signal; determining, based on the first signal strength and on the second signal strength, a movement indication for a movement of the first RFID-enabled device towards a target position, at which there is expected a target RF coupling strength between the two RFID-enabled devices, which is stronger than a first RF coupling strength being associated with the first position and a second RF coupling strength being associated with the second position; and (h) providing the determined movement indication to the user of the first RFID-enabled device. In other embodiments, an RFID communication system and device are provided.

A wireless tag (1) includes: an antenna (14) that receives an access signal transmitted from a reader/writer; a decoding unit (15) that decodes the access signal received by the antenna; a detecting unit (12) that detects input of a signal corresponding to a user operation; and a control unit (13) that performs processing corresponding to a combination of a result of detection of the detecting unit and a result of decoding of the decoding unit, the results being obtained in parallel.

Provided are systems, methods and devices for increasing security in a financial transaction when using a smartcard. The system includes a smartcard for payment in a financial transaction, the smartcard having a memory for storing a first actuation sequence for confirming a user's identity; wherein the smartcard has a checking module that authorizes the transaction only when a second actuation sequence is identical to the first actuation sequence stored in the memory; a point of sale terminal for recording payment details from the smartcard once the financial transaction is authorized and transmitting a request for payment through a network to a financial institution according to the payment details; and a financial institution authorizing computer for allowing recording of an actuation sequence on the smartcard and making payment to the owner of the point of sale terminal once the transaction is authorized, according to the payment details.

Apparatus, methods and systems for voice surveillance using enhanced metadata and geotagging capabilities are provided. Systems may monitor communications being transmitted from, and being received at, entity devices. The communications may be monitored for anomalies. The anomalies may be identified as communications outside of a regular pattern of communications. Various factors may be used to identify the anomalous communications. The factors may include a number of communications per predetermined time period, a geolocation of the communication, identification of a second communicative party of the communication and any other suitable factors. Stakeholders may be alerted regarding any anomalous communications. Additionally, once the communications have been labeled as anomalous or non-anomalous, the labeled communications may be used to create and/or update a set of labeled training data. The created and/or updated set of labeled training data may be used in an artificial intelligence engine that labels communications as anomalous or non-anomalous.

A locator chip device is disclosed, which is a color-coded locator chip to be secured to a household or personal item. The locator chip device comprises a chip component that is configured in various shapes and sizes with an adhesive backing. The chip component is secured to an item and a smartphone application allows a user to assign each color of chip to a specific item. If an item is lost, the user selects the corresponding color in the app to locate it. The chip components can also be located via an audible sound or a visual indicator that quickens as one nears the lost item. Additionally, users can use their phone's vibrate feature for assistance. There is no limit as to what items can receive a color-coded chip component. People can place the chip component on the item and track it via the smartphone application with ease.

Authentication systems and methods using orientation sensor-enabled payment cards are disclosed herein where a server receives an authorization request from a web server or an electronic terminal. The server then transmits an instruction to the orientation sensor to determine whether the payment card has an orientation that is consistent with a predetermined orientation. When the payment card has an orientation consistent with the predetermined orientation, the server executes a first authentication protocol. However, if the payment card has an orientation that is not consistent with the predetermined orientation, the server executes a second authentication protocol that is more restrictive than the first authentication protocol.
