Abstract: An object includes an NFC tag, which includes NFC data. The object also includes a barcode, which is an encoded representation of barcode data. When someone wants to access the NFC tag data, the object is presented to an object-reading system that includes both an NFC reader and a barcode reader. The barcode reader is used to read the barcode on the object in order to obtain the barcode data contained within the barcode. The barcode data is then used to establish a secure communication channel between the NFC tag in the object and the NFC reader. The NFC reader then utilizes the secure communication channel to read the NFC tag in the object.

Abstract: A computer-implemented method for controlling playback of a schedule of feedback elements to be presented at an output of an electronic device, the feedback elements each associated with one or more predefined metrics, includes the steps of, during playback of the schedule: receiving sensor data from one or more sensors associated with the electronic device; upon determining that a first trigger condition is satisfied, determining whether the sensor data satisfies a metric threshold condition, in response to the metric threshold condition being satisfied, modifying the schedule of feedback elements for presenting at the output. An associated computer readable medium and electronic device are also described.
