Q: Would like to know how I can scan and take a pic of my iTunes card and send to cust support to redeem my code

If you just want to redeem the card then you shouldn't need to scan it in nor contact Support : redeeming a card.

If you are having a problem with the code and need to contact Support about it then if you have a computer or a mobile phone with a camera on it then you can take a picture with that - or you can use a digial camera and import it to your computer so that you can attach it.

Contacting Support about gift cards : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then iTunes Cards And Codes
