Your cards ship blank so you can link each one to a different business. No experience needed. If you can copy and paste, you can do this.
Download NFC Tools (free) on your phone:
You'll need an iPhone 7 or newer, or an NFC-capable Android. Your customers who tap the card later need nothing installed.
Ask the business owner for their “get more reviews” link from their Google Business Profile, or paste their name / Google Place ID below to generate a link you can use:
Tip: use a new blank card for each business. Every card holds its own link, so one card = one business.
Tap the card with any phone. It should instantly open that business's Google review page. Done. Hand it over and move to the next business.
Need to change it later? Just write over it again with a new link. The same card can be reused as many times as you want.
