I guessed so, googled the information about inventory before here.
I guess I can create some web interface for this purpose, add new item by EAN, let it find some info and then add it to shopping date and mark the price, then again and again.
Or rather look for something that already does this + supports scanning bills.
EDIT: This Android app seems like it (seems its only in German)
EDIT2: Nah, its just take photo and manually add price to it, could not expect it from it to do OCR and guess everything.
