I think if you look a the past you will find quite a few countries that have already been there, done this. It never turned out as bad as your imagining. Canada has very strict gun control and this is on top of the fact that having a gun here is a privilege not a right. Yet I can go into any store that sells guns right now and buy one. The store simply takes my gun card, swipes it, moves the gun on their computer from their inventory to mine and box it up for me to leave with. Daily the gun data bases of gun dealerships send into the gun registry the transactions. In about 10 days the certificate that registers it to me shows up in my mail box. Done deal, that's it. Private sales are handled on the web or by phone, same thing, record transferred, gun changes hands.
So what difference can that make? Well if your traveling with a gun for a lawful reason I don't see why you would find having a gun card in your wallet a big deal. If you get stopped by the police they run the number with no more difficulty than your driver's license and see that in fact you own that gun. No problem. But if your on the way to rob a bank likely you don't want the gun traced to you, so it's not yours, you got it off the black market, or since your a robber anyway you stole it. They catch you speeding and wow, you don't have a gun card, and that gun is not registered, or has been reported stolen. Hmmmmm. Easier to track crime.
The only thing I see it forcing the legitiment gun owner do is report lost or stolen guns, and keep them stored safe for prevention of misuse. I see that as a good thing. One thing to note is that I can also carry any gun I don't own, then it just gets recorded that I was carrying it. I guess if there was any question they would contact the owner to confirm. Often people pack notes from the owner if they are taking other's guns out to the range or hunting.
