Review on 👥 Smart Followers for Facebook Stickers by Daniel Postle

Works like a charm! Super easy to set up (make sure you have NFC enabled if you want this feature to work, it won't work automatically if it's not already enabled on your phone). If you have a business, make sure you link it to your business page and not a personal profile. After activation, make sure NFC and QR code are working. Glue it to anything other than metal and you're done. This size is small (see image for scale) but perfect for my needs. After a year you have to pay about $3 to reactivate it, if it does what it's supposed to, no problem.
