I just set up a personal wallet, and the QR code on my phone, looks different from the QR code that blockchain.info shows. When I scan, the code on blockchain.info, I get the same address. I thought the QR codes were Unique.
what is going on? This is a new wallet, and I used the copay app, to create it.
Im not sure how to get the QR code off my phone, this is why I went to blockchain.info, so I could get an address I can print. The image from blockchain.info
Using HD wallets gives you access to a multitude of addresses. Each wallet could simply be generating a qr code for different addresses (both of which you own). Can't say for sure unless you share the qr codes. – Dylan James McGannon – 2016-08-29T07:45:44.377

QR codes can in fact differ even when they encode the same data, because they may be generated with different levels of error correction. See http://blog.qrstuff.com/2011/12/14/qr-code-error-correction for a pretty readable explanation.
