What is the downside of QR codes?

QR codes are convenient, but they rely on technology that can let you down. If the link behind the code expires, moves or is taken down, the code becomes useless. This can happen if you use a free generator that stops hosting your link, or if you forget to renew a website domain. Always keep a copy of the live link somewhere safe.

Not every guest is comfortable using a phone camera to scan. Older relatives may find the small square hard to aim at, and some phones need a few tries. A written web address printed below the code helps everyone. You can also put the address on a separate card so guests who prefer it can type it in.

Printing quality matters too. A QR code that is too small, pixelated or printed on a reflective surface may not scan. Test several copies on different phones before you send anything out. For larger events, a wedding website with RSVP for every event and a guest dashboard can reduce the pressure on individual codes.
