A system has a measuring device providing a quantitative output of a physiological condition of a subject, a non-transitory identifier affixed to a surface proximal to the measuring device, an imaging apparatus having an Internet connection, and an internet-connected server coupled to a data repository, the Internet-connected server executing coded instructions on a processor. The physiological measuring device is engaged, providing a quantitative indication of the physiological condition of the subject, an image capture of the readout and the non-transitory identifier is captured by the imaging apparatus in a single image, and the captured image is transmitted to the internet-connected server.
