You have probably seen all three of these on a counter at some point: a QR code taped to a till, a small stack of tap cards, and occasionally a sticker asking you to switch on Bluetooth. They are often described as if they compete with each other, but they solve different problems, and the right choice for your business usually comes down to where the customer is standing and what they are holding. Here is an honest comparison, including the cases where the simplest option wins.
Three tools, three different jobs
NFC, QR codes, and Bluetooth are all ways of moving a customer from a physical object to a digital destination, but they get there through very different doorways. NFC is a short-range tap that needs no aiming. A QR code is an image that the phone's camera has to see clearly. Bluetooth is a wireless connection that pairs two devices and keeps them talking. Only two of those three really belong on something you print and hand to a customer, and it is worth understanding why.
Where QR codes win
A QR code is cheap to produce and needs no special hardware at all. You can print one on a receipt, a poster, a window, a menu, or a business card, and it works with essentially any modern phone. If your goal is to put a link in as many places as possible for as little as possible, a QR code is hard to beat.
The trade-off is aiming. The customer has to open the camera, point it at the code, hold still long enough for it to register, and tap the link that appears. In good light and on a flat poster this is quick. On a dusty table stand, a curved surface, or a code that has faded in the sun, it becomes a small negotiation every time. A dynamic QR code fixes the awkwardness of changing the destination, but it cannot fix the aiming.
Where NFC wins
An NFC tap removes the aiming entirely. The customer holds the phone near the card and the link opens. There is no camera, no brightness problem, and no need to steady a hand. For a review request this matters, because it sits inside a moment where the customer is already halfway out the door.
NFC is the better fit wherever the interaction needs to be frictionless and repeatable: a table stand that hundreds of people will use, a card at a till, a tag on a product. Most phones read our tags with no app installed, and the range of 2 to 5 cm keeps the card from reacting to phones that are merely nearby. The one requirement is that the phone has NFC switched on, which is standard on current phones. You can see the formats we offer on our products page.
Why Bluetooth rarely belongs on a printed card
Bluetooth is excellent at what it was designed for: keeping a steady connection between two devices over a few metres, such as a phone and a speaker. It is a poor fit for a one-time tap. It usually requires pairing, it drains battery on both sides, and it needs the customer to approve a connection before anything happens. For the simple job of opening one web page, Bluetooth adds setup and gives nothing back. You would not print it on a review card, and you would not expect a customer to bother.
Printing both: the practical choice
You do not have to choose only one. A card can carry an NFC chip and a QR code together, so a customer with an older phone or NFC switched off can still scan, while everyone else just taps. This pairing is one of the most common requests we get on our customization page, and it is a genuinely sensible way to avoid leaving anyone out.
As a rule of thumb: choose QR alone when you are covering many surfaces cheaply and the customer has time to aim, choose NFC when the moment is quick and repeated, and treat Bluetooth as a connection technology rather than a review tool.
