Our NFC products are physical tools you use to share your page with other phones. There is no limit to how many of these products you can have activated in your account or page. Usually, users will have at least one product per page they have created on their account because products can only pull up one page at a time.
If you have multiple business or personal pages on your account, your options are to have one product per page or just one product that you must change the page it is paired to before sharing.
You can switch what page your product is assigned to at any time. This is done by going to Products and selecting the activated product in the list. Then, you will choose Pair with a Different Page. This is how you would change your page assignment with just one product. Or you can have a product paired to each page that doesn't need to be changed.
