Yeah, some irony that there's a Facebook promoted ad on the LinkedIn home page. Apparently these companies do realize that we use more than one social media service after all.
The link you want to tap is as unobvious as it could be: Look at the top in the Search box. See on the right side of the search box there's a mini-grid of four squares, three solid, one that's dots? Not the 3 x 3 grid on the light blue background, the 2 x 2 that's actually in the search box itself. That's what you want to tap. Carefully tap that link and you'll be in LinkedIn Code mode:
Notice you can scan saved photos and live scan other LinkedIn Codes if you enable camera access here. We don't want to do either (though if someone asks you how to scan your own code, this shows you what to tell 'em). Instead, tap on the greyed out My code and¦ voila!
Pretty cool, eh? Now, you can just screenshot this image and use it, but let's share it on Facebook so I can get some of my Facebook friends to connect to me on LinkedIn too. That's done by choosing Share my code, though also notice that you can also Save to photos and you have the image all ready to use in other contexts.
Once you choose to share your LinkedIn Code, you need to figure out if it's just the image, or the whole thing with tiny photo, description, etc:
I'll share the code only, which takes me to the standard iPhone share options:
A swipe right to left on the upper row and the Facebook icon comes into view. A tap and¦
That's it. I can leave whatever message I want and hopefully gain a few new LinkedIn connections as part of this process. And heck, even if not, at least I know how to work with LinkedIn Codes now, and so do you!
