QR or NFC for a Memorial? Which One Actually Lasts

Once families start looking at memorial technology, the NFC question comes up quickly. Tap-to-open feels newer, cleaner and more impressive than a printed pattern, and there is no visible code to argue about with a cemetery.

For most memorials, QR is still the right answer. But not for all of them, and the exception is genuinely interesting.

How each one works

QR is optical. A printed or engraved pattern encodes a web address, and a camera reads it. It needs line of sight and reasonable light. Nothing in the plaque is electronic.

NFC is electromagnetic. A tiny chip and a coiled antenna are embedded in the plaque. A phone held within about four centimetres generates a field that powers the chip, which transmits its stored address back. There is no battery, so the chip does not run down, but it is an electronic component rather than a marking.

That distinction, marking versus component, drives almost every difference that follows.

Failure modes, which is the real comparison

This is where memorials differ from every other use of these technologies, because a memorial is not maintained by anyone who is watching it.

QR fails gradually and visibly. Lichen creeps over a corner. Grit dulls the contrast. Scanning gets less reliable, then stops. You can see the cause, and the fix is a damp cloth. It also fails partially, because error correction lets a code survive substantial damage before it gives up.

NFC fails suddenly, completely and invisibly. A chip is either working or it is not. Water reaching the chip, a sharp impact, or a strong static discharge kills it outright, and the plaque looks exactly the same afterwards. There is nothing to clean and nothing to diagnose.

Now the part that matters most for a memorial. If a QR plaque is damaged, destroyed or stolen, an identical replacement can be made, because the code is information rather than hardware. The same pattern, cut again, points at the same page. Nothing is lost.

If an NFC chip fails, the tag must be physically replaced and re-encoded. On a plaque adhered to a headstone, that means a mason, potentially a fresh permit application, and a cost that can exceed the original memorial. On something set into stone, it can mean it simply never gets fixed.

Good encapsulated NFC tags rated for outdoor use are genuinely robust. But their worst case is worse, and their failure is one nobody discovers until someone taps a plaque on an anniversary and nothing happens.

Who can actually use them

QR works on essentially any phone with a camera made in the last decade, through the standard camera app, with no setup.

NFC is supported on most modern phones, but with caveats that matter for a memorial audience. Background tag reading works on newer iPhones and not on older ones. On some Android handsets NFC can be switched off in settings, and a phone with it disabled will do nothing at all when tapped, with no explanation offered to the person holding it.

There is also a familiarity gap. Scanning QR codes became a national habit during the pandemic, and people over seventy do it in pub gardens without thinking. Almost nobody's instinct is to touch a phone against a headstone, and there is no way to signal it on the plaque without adding the instruction, which rather defeats the clean look that was the appeal.

For a memorial, the audience is the general public across every age group, arriving without instruction. That favours QR heavily.

The reach problem

NFC needs about four centimetres. QR reads from roughly ten times the code's width, so half a metre for a 50mm plaque and about a metre for an 80mm one.

This has a practical consequence people do not anticipate. Cemetery memorials are often behind a kerb, a planted border, or a low chain. A visitor can stand at a respectful distance and scan a QR code. To read an NFC tag they must lean across the grave and press a phone against the stone, which many people are reluctant to do at somebody else's memorial, and which is physically difficult for anyone with limited mobility.

QR also works from things that are not the plaque. A photograph of it. The order of service. A memorial card. An email. A screen. Anyone who took a picture of the headstone on the day has the memorial with them permanently. NFC cannot do any of that, because it is not visual.

The one case where NFC wins

NFC has no visual footprint. The tag can be concealed entirely beneath a conventional engraved plaque, so the memorial looks completely traditional and nothing machine-readable is visible.

That is not merely an aesthetic advantage. It is a regulatory one.

Where a churchyard's regulations prohibit modern or commercial-looking features, or a conservation-area cemetery enforces strict visual uniformity, the objection is very often to the appearance of the code rather than the existence of a digital memorial. See the churchyard regulations guide for how that reasoning works. A hidden tag under a plain bronze plaque removes the visual objection entirely.

Be straightforward about it rather than sneaky. Concealing something from the authority that approved the memorial is a poor foundation, and permission granted knowingly cannot be withdrawn later on the grounds that nobody was told. Tell the incumbent what is in it and ask.

NFC is also better in the dark, on an urn or frame handled at close range indoors, and in any setting where people are already accustomed to tapping.

Cost

Broadly comparable. A quality outdoor-rated NFC plaque typically runs a little dearer than an equivalent engraved QR one, because it contains a component rather than only a marking. The meaningful difference is not the purchase price but the replacement cost after a failure, where QR is a new plaque and NFC is a new plaque plus, possibly, a new permit.

The straightforward recommendation

Choose QR for almost every memorial. It is readable by everyone without instruction, at a distance, in daylight, from photographs and printed matter as well as from metal. It degrades visibly and repairably rather than dying silently. It is an open international standard no company controls. And it can be recreated identically, for a few pounds, forever.

Choose NFC where a visible code would be refused or would genuinely spoil a memorial you care about the appearance of, and where the people using it will be told how.

Choose both if the budget allows and the plaque is large enough. They coexist happily, and the redundancy means one can fail without the memorial failing.

Whichever you pick, the questions in how memorial QR codes work matter far more than the choice between them. A dynamic code you can repoint, a full export of your own files, no subscription that can lapse, and a printed copy will preserve a memorial for longer than any decision about chips and patterns.

Our own plaques are QR, marked into stainless steel, at 50mm and 80mm.
