Instead of reading or scanning data from a source document what kind of device obtain data?

Devices that obtain data without reading or scanning source documents include sensors, such as temperature or humidity sensors, which collect real-time data from their environment. Additionally, RFID (Radio Frequency Identification) systems can automatically capture data from RFID tags attached to items without needing direct line-of-sight. Other examples include barcode scanners that input data directly from barcodes and IoT devices that transmit data wirelessly.
