Logic may detect a malfunctioning payment interface on a customer's payment instrument. Logic may receive transaction data about at least one transaction performed via a payment instrument associated with a customer. The transaction data may indicate a payment interface of the payment instrument through which the customer conducted the at least one transaction and the payment instrument may comprise one or more payment interfaces. Logic may determine, by a model, based on the transaction data, a probability of a malfunction by at least one interface of the one or more payment interfaces. The model may be trained based on a pattern of transactions associated with malfunctioning payment instruments. Logic may compare the probability of the transaction against a threshold. And logic may determine whether to contact a customer associated with the payment instrument, based comparison of the probability of the transaction against the threshold.

A closed container includes a detection device for detecting opening of or an attempt to open the container. The detection device includes a contactless passive transponder that is configured to communicate with a reader via an antenna using a carrier signal. An integrated circuit of the transponder includes two input terminals connected to the antenna and two output terminals linked by a first electrically conductive wire having a severable part which is severed in the event of an opening of or an attempted opening of the container. A shorting circuit is configured to short-circuit a first output terminal with a first input terminal in the event of a conductive repair of the severed part which forms an electrical connection between the two output terminals.

Dual-mode RFID devices are provided with an integrated dual-mode RFID strap including either a UHF/HF dual-mode RFID chip or the combination of a UHF RFID chip and an HF RFID chip. An HF antenna and a UHF antenna are both coupled to the integrated dual-mode RFID strap, with the UHF antenna being formed by an approach other than etching, such as a cutting or printing operation, thereby reducing the cost to manufacture the device. If a pair of chips is employed, one of the chips may have a greater thickness than the other chip, which allows for the thicker chip to be incorporated into the device after the thinner chip without requiring a minimum separation between the two chips due to the size of a thermode used to secure the chips. Additionally, the first chip may be tested before securing the second chip, thereby limiting the cost of a rejected device.

A Radio Frequency Identification (RFID) tag IC stores an identifier and a check code. The IC determines whether the stored identifier is corrupted by comparing it to the check code. If the stored identifier does not correspond to the check code then the IC may terminate operation or indicate an error. The IC may also reconstruct the correct identifier from the check code.

A memory card identification method and a mobile device are provided. The memory card identification method includes: sending an initialization command of a first-type memory card communications protocol to a to-be-identified memory card; detecting whether there is a response in a command pin of the memory card; and identifying the memory card as a first-type memory card or a second-type memory card based on a response status of the command pin.

A method of manufacturing incontinence detection pads that have wireless communication capability includes readying an RFID tag applicator to place RFID tags on backsheet material fed between a pair of nip rollers. The backsheet material has a series of electrode traces thereon. The method also includes operating a nip roller motor to feed the backsheet material between the pair of nip rollers and toward the RFID tag applicator, operating the RFID tag applicator to place each RFID tag across regions of a respective electrode trace of the series of electrode traces, and operating RFID tag test equipment to energize each RFID tag a first time and a second time using wireless emissions and receiving return signals from each RFID tag in response to the wireless emissions.

A device for managing operation of an object capable of contactless communication with a reader magnetically coupled to the object includes a modulator configured to modulate an impedance of a load connected across terminals of an antenna of the object during a transmission phase during which information is transmitted from the object to the reader. The device further includes a monitor configured to carry out a monitoring phase, prior to the transmission phase. The monitoring phase includes a test modulation of the impedance of the load, a monitoring of a level of amplitude modulation of a modulated test signal present at the antenna of the object and resulting from the test modulation, and a capacitive modification of the impedance of the load if this level is lower than a threshold.

An integrated circuit for a radio-frequency identification (RFID) tag is described. In an example embodiment, the integrated circuit (101) comprises: a memory (104) for storing data; a transceiver (107) for receiving signals from, and transmitting signals to, an antenna (102); and a controller (103) configured to process signals received via the transceiver (107) and to access data stored in the memory (104); wherein upon receiving, via the transceiver module (107), a lock command referring to a data block in the memory (104), the controller (103) is configured to perform a data integrity check on the data block to determine whether the data block is strongly stored.

A Radio Frequency Identification (RFID) tag IC stores an identifier and a check code. The IC determines whether the stored identifier is corrupted by comparing it to the check code. If the stored identifier does not correspond to the check code then the IC may terminate operation or indicate an error. The IC may also reconstruct the correct identifier from the check code.

In some embodiments, system, apparatuses, and methods are provided herein useful for managing retail product inventory including a plurality of locations each having a corresponding location decay rate associated by a central control system. A central control system comprising a central control circuit coupled with memory storing code that when implemented causes the central control circuit to: determine, at a current time and for each detected first product, a confidence value corresponding to a level of confidence that the first product is still present and within a first threshold area corresponding to a first location where the first product was most recently sensed. The confidence value may decay over time proportional to a first decay period of time.
