Apple’s mobile payments system, Apple Pay, was launched this week, and is working in national retail chains like Macy’s, Whole Foods, Walgreens, and Subway. Quartz has a guide to how it all works. Essentially, you’d connect one of your credit cards to your iPhone, and an antenna in your phone would automatically bring up the payments system when you’re ready to pay. You’d then pay using the fingerprint Touch ID system on your phone.
I have three different signatures that I use:
• My full name in legible cursive, which I use when signing personal checks and legal documents
• An abbreviated version of my name, which I use when signing anything digitally
• A scribble, which I use when I’m signing receipts for various merchants
