Can a memory card reader be attached to iphone 5 to view and email pics?

I'm heading on holidays and don't want to have to carry both my camera and iphone 5 with me all the time (my camera is much better for quality pictures). Is there a memory card reader or likewise that I can connect my iphone5 to at the end of the day to upload my photos from my camera/memory card?

NO You can't. Only IPAD has the Lightning to SD card Adapter… However you can transfer your Photos to Itunes first then onto the SD or memory stick. Please see Link below

Yes you can purchase any card reader and connect this card reader to your iPhone and transfer your pics from card reader to Iphone.
