NFC tags are small stickers that store data, allowing you to automate daily routines with a smartphone. With a quick tap, a staff member, for example, could trigger a checklist for doing your closing down procedure, or you could use an NFC tag to direct a customer to a social media page or reviews about a product or service. You could set one to turn on your store’s Wi-Fi and launch your music app when you arrive at work, or prompt everyone to mute their phones at the start of a meeting. The tasks are easy to set through iPhone’s Shortcuts app (or an app like NFC Tools for Android), and at 30 to 40 cents apiece, cheap enough that you can experiment wildly. And if you come up with a neat use for a jeweler, let us know!
