associate the model identifier with a device configuration stored in the memory, the device configuration including data indicative of a relative location of the NFC antenna of the device and a camera location at which the camera of the device captures the images;
associate the type of the document with a document configuration stored in the memory, the document configuration including data representative of a relative location of the NFC antenna of the document;
generate alignment feedback based on image processing of video of the document, the device configuration and the document configuration, the image processing further comprising processing video images of the document to:
(1) identify the document;
(2) identify a location of a document target on the document; and
(3) overlay a location of an image target on at least one live video image of the video images, the image target being a graphic overlay shown on the display of the device:
the alignment feedback including alignment indications produced according to alignment feedback schema and providing guidance to a user for aligning the NFC antenna of the device and the NFC antenna of the document, the aligning of the NFC antenna of the device and the NFC antenna of the document occurring when the camera of the device is aligned with the document target, the location of the document target being different than the location of the NFC antenna of the document;
detect for a data connection between the device and the document; and
generate a connection indication when the data connection is detected.
11. The system of claim 10 , wherein the processor is configured to read as the model identifier one of a processor readable number, sequence of numbers, ACII string, or other encoded processor readable string that identifies a model of the device.
