Is it legal to take a photo of fishing license to show proof of purchase?

With todays age of personnel electronics. Would it be legal to use a photo on my phone to show proof of purchase for a hunting or fishing license? Since we can print our license at home if we purchase online. And is IFG looking into having an app. that will show proof?
Answer: 
Thank you for your question. Yes, you may take a picture of your license and store it on your mobile device as proof of having a license. We do not have any plans to build an app for licensing. However, we do have a mobile optimized website and those who purchase their license via a mobile device now download their license to their mobile device rather than receiving a printed license. Please contact us again if you have additional questions.
