NFC and NFC tags
NFC means near-field communication. A compatible phone can read a nearby NFC tag, such as the chip in a smart card. A web-link tag tells the phone which address to open; it does not install an app or write a review. Phone support, settings and reading position affect the result, so an NFC feature on a specification sheet is not a guarantee for every interaction.
NearvoQ cards store a card link in the chip. The owner changes its destination in their account rather than rewriting the chip. See how NFC business cards work.
QR code, modules and quiet zone
A QR code is a machine-readable square pattern. Its small squares are called modules. The pattern can encode a web address, contact data or another supported payload; scanning does not tell you whether that content is trustworthy.
The clear border around a standard QR code is its quiet zone. DENSO WAVE specifies four modules on each side. Print size also depends on the amount of encoded data, camera, distance and conditions; a border alone does not certify scanning. Use the QR checker and test a physical proof.
Static code and dynamic link
A static QR code contains data that cannot change after it is printed. When that data is a URL, the website at that address can still change. A code that contains contact details directly needs reprinting if those details change.
A dynamic link adds a redirect managed by a service. The printed address stays the same while its final destination changes. The service must keep the redirect working; dynamic does not mean independent of the provider. Read dynamic versus static QR codes.
vCard and contact QR
A vCard is a standard contact-data format, often downloaded as a .vcf file. A supported contacts app can import the name, phone, email and other fields. A contact QR can encode that data directly, while a profile-link QR opens a page with a contact download.
A saved contact is a snapshot. Editing an online profile does not silently change contacts already stored on other phones. They need to obtain and save the new information. See what a vCard is.
Profile URL and permanent card link
A public profile URL identifies the online page someone shares. A NearvoQ profile uses /p/ followed by its handle. Changing the handle changes this direct address, so check printed links before renaming it.
NearvoQ's physical cards use separate permanent routes: /t/ for NFC and /q/ for QR. Both resolve to the owner's chosen destination. They are different URLs so taps and scans can be distinguished; they are not two separate profile accounts.
Google Place ID and review-request link
A Place ID identifies a place in Google's systems. It can be used to construct a link to a business's review form. A Maps listing link and a dedicated review-request link do not always open the same screen, so test the exact business before printing.
A review-request link invites the customer to write their own feedback. It cannot create a review, choose a rating or ensure Google publishes it. Share requests consistently without rewards or satisfaction filtering. See how to find your review link.
Tap, scan, profile view and contact submission
These are distinct events. A tap or scan opens a card link; a profile view loads the hosted profile; a contact submission sends details the visitor chooses to provide. Not every tap becomes a profile view when the card goes directly to another website.
Activity counts do not prove a completed booking, a published Google review or a sale on another service. Testing and owner activity may be excluded. Use counts to understand recorded interactions while keeping the distinction between an opened destination and a finished outcome.
