Hi, I dont know whether my question is right to ask here. please advise me if I need to ask this kind of question at other areas. I am investigating to find a right portable scanner to connect with an Android mobile phone (such as HTC Desire). After scanning a paper from a portable scanner, the mobile phone will receive the file as a pdf or jpg. That's it! This connection is either visa USB or bluetooth? Would this be possible to do? Which portable scanner is applicable? Thanks in advance.
