What if your next swag was a donation? That's what Cockroach Labs did.
Ok, so the typical way of doing swag at a conference is to give out t-shirts for badge scans.
And then folks either wear them or throw them away (or keep wearing them when they should have thrown them away but that is another story).
After the conference you take leftovers with you, ship them home or, you guessed it, throw them away.
A lot of throwing away for a badge scan if you ask me.
Cockroach Labs decided to do something completely different.
They donate a few $ to a great charity @Women Who Code for every badge scan they get.
I love it.
An extra benefit (and where the idea originated) is that with this, you can do virtual badge scans too.
