    Abstract: A method, an apparatus, and a system for testing a terminal. The method includes: receiving a smart card switching instruction; acquiring a card channel identifier from the smart card switching instruction; switching a connected-card channel to a target card channel corresponding to the card channel identifier when the target card channel corresponding to the card channel identifier is a contactless card channel; receiving a data request for a terminal test; acquiring, through a first relay repeater, response data in response to the data request, from a smart card to be tested within the target card channel; and sending, through a second relay repeater, the response data to the terminal whereby accomplishing the terminal test.

    Abstract: A method for a phase calibration in a frontend circuit of a near field communication (NFC) tag device is disclosed. An active load modulation signal is generated with a preconfigured value of a phase difference with respect to a reference signal of an NFC signal generator device. An amplitude of a test signal present at an antenna of the NFC tag device is measured. The test signal results from overlaying of the reference signal with the active load modulation signal. The following steps are repeated: modifying the value of the phase difference, providing the active load modulation signal with the modified value of the phase difference, measuring an amplitude of the test signal and comparing the measured amplitude with the previously measured amplitude until the measured amplitude fulfills a predefined condition. The value of the phase difference corresponding to the previously measured amplitude is stored.

    Abstract: Methods and systems are provided for testing and/or programming a thread-type string of RFID tags or devices. A thread-type RFID tag is formed on a length or thread having an RFID chip, a first antenna section and a second antenna section, the first and second antenna sections being positioned on the length of thread on opposite sides of the RFID chip. An RFID reader is positioned in electronic communication with a first coupler and a second coupler lying along a path, and the RFID tag and couplers are in relative motion with respect to each other such that the first and second couplers are on opposite sides of the RFID chip. A differential electric field is applied between the first coupler and the second coupler and across the RFID chip whereby the RFID reader couples to the RFID chip and interacts with the RFID tag to carry out testing and/or programming tasks with respect to the RFID tag.

    Abstract: A system and method for calibrating a barcode scanning tunnel comprises providing a scanning tunnel having a moveable surface, a camera, and a dimensioning device. Orientations of the dimensioning device and camera are estimated. Instances of a calibration object on the moveable surface are acquired by the dimensioning device and the camera, and a relationship is defined between the two devices. A calibration object is moved along the moveable surface through the devices' fields of view, controlling the camera's focal distance according to the relationship, so that the dimensioning device and the camera acquire instances of the calibration object, and the relationship is revised.
