As someone who hates relying on devices for everything, I've come to tote around personal calling cards - little "business" cards with fun photos, my contact info and website. Apparently, calling cards are making a comeback.
People are always enamoured by the small, rectangular cards I dole out - they are always a conversation starter. They're great for networking events, job interviews, trade shows. Any situation where you might need to connect but don't have a pen, and don't feel like unlocking your phone, opening your contacts and typing in details (which I find dreadful).
Long story short: I get my minicard from Moo.com. People are always commenting on them and asking where they can get them. I just reordered a bunch and have a discount code to share with you!
