Materials

Stainless steel and ceramic work best: they stand up to rain, frost, and UV light and last for decades. Paper and ordinary plastic stickers are no good outdoors — they fade within a season. Engraving on metal lasts longer than printing.

Size and contrast

The ideal code size is at least 3 cm per side, so a phone can read it reliably. Contrast matters: a dark code on a light background scans fastest. Don't make the code too small or glossy — glare interferes with the camera.

Mounting

The plaque is attached with stone adhesive or with screws into pre-drilled holes. Place it where it's easy to bring a phone close — usually on the lower part of the headstone. Keep in mind that in winter snow can cover the lower portion.

Where to order

QR plaques are made by workshops that do engraving and headstone production. Bring a ready file with the code, or a link — it will be transferred onto metal or ceramic. Ask about the warranty on the coating's durability.

  • Steel or ceramic, ideally engraved.
  • Code at least 3 cm, with good contrast.
  • Mount with stone adhesive or screws.
  • Order from engraving workshops.

Frequently asked questions

How long will a metal plaque last?
Quality engraving on stainless steel withstands outdoor conditions for many years without fading.
Can I make the plaque myself?
Printing a code is easy, but outdoors you need a durable base — it's better to order engraving on metal or ceramic.
