I have a customer in the aviation industry.  When they receive purchases (also when they ship sales), there is a lot of paperwork, such as certificates of conformity, that must be scanned and associated to the receipt.  One way to do this would be to scan the documents and then attach them using the paperclip icon that appears in the chatter of just about every module; however that would not be very efficient.  What we would ideally like to do is launch a camera from the receipt, similar to clicking the paperclip icon but instead of then browsing for a document, you just take a photo of the document and it is automatically attached to the receipt.  Has anyone done something like this? If not, what process do you use to attach documentation to Odoo records such as receipts? Thanks
