What I want to do is use the camera shield with an arduino uno to see if something is a QR code, and then if it is store it on a SD card. Is something like this possible or is that too much work for the arduino to handle? If it is, any suggestions on other ways to do it? The end goal being to read the SD card using a computer to pull the information off the QR code and then do the processing on the computer.
One thing I am trying to avoid is having to use my phone to scan the QR code. It's a personal project to see if my end goal, the final creation will be possible. This is the only thing I am not sure about and have no idea where to start with.
Do you think it would be any more feasible using an arduino mega?

Which camera shield? With which camera?
to see if something is a QR code
Do YOU know how to recognize, based on a bunch off pixel data, whether something is a QR code?
There are smart phone apps that can do it, so you might get lucky and find some code to do it.
and then if it is store it on a SD card.
Store what on the SD card?

Think about whether you would be better off connecting the camera directly to the PC in that case. Once you have the image on a PC you are far better placed to recognise and process it. If the solution needs to be hand held, you could consider basing in on a RPi, however it seems to me that a smart phone would be by far the most sensible platform.
