Choosing QR, NFC, or both

FoundYa can use either a QR code or an NFC tag or both on the same product. They can open the same pet profile link for finders - and you can use the same technologies for at-home shortcuts (logging walks, feeds, meds, and more). Here’s how to choose what to offer customers.

What’s the same

• One profile link - Whether someone taps an NFC tag or scans a QR code, they can reach your pet’s FoundYa page (contact options, lost mode, and messaging depend on your settings).
• No separate “QR app” - The QR is just a normal web link. The phone camera opens it in the browser, like any website.

NFC tags (tap)

Best when you want:

• Fast for finders - Tap the tag with a phone; no need to open the camera app or line up a code.
• Works well outdoors - Easier than scanning a dirty or curved QR in poor light.
• Optional extra data on the chip - Depending on tag type and setup, additional info (for example basic pet notes) can be stored on the tag so a small amount of text is readable without internet on some phones.
• Stronger physical control - Tags can use chip-level protection so the stored link is harder to overwrite without your app and account (details depend on tag type).

Trade-offs:

• The phone must support NFC (most modern phones do; some older or budget models may not).
• Slightly higher cost than a printed QR alone.
• Physical damage can stop NFC entirely - If the tag is cracked, chewed, or the antenna is torn, the chip may no longer tap - there is nothing to “error correct” on the electronics side. That’s another reason many products pair NFC with a backup QR.

QR codes (scan)

Best when you want:

• Universal phones - Any smartphone with a camera can scan a QR code; NFC is not required.
• Low cost at scale - Printing a QR on packaging, a collar card, or a poster is inexpensive.
• Easy to add later - You can put a QR on a leaflet or box without embedding electronics.
• Built-in error tolerance - QR codes include error correction (standard in the format). Minor scuffs, small tears, or partial obstruction often still allow a successful scan - unlike a damaged NFC tag, which may not respond at all.

Trade-offs:

• Finders must open the camera (or a QR app) and frame the code - a bit slower than a tap, especially in glare or if the sticker is badly damaged (severe tears can still defeat any code).
• A QR is just a picture of a link - anyone who can see or photograph the code can open the same URL. Treat it like a public link: avoid posting high-resolution photos of the QR in public posts if you’re worried about misuse (same idea as sharing any public URL widely).
• Printed codes don’t update themselves - If your pet’s link ever changes in a way that requires a new web address, NFC can often be updated from the FoundYa app, but a printed QR stays fixed until you print a new one.
• You can’t “rotate” ink - A QR on a poster, flyer, or product is a snapshot of one link. If that link is ever shared widely (for example a photo of the code on Instagram, a community post, or a screenshot), that same URL can stay public forever. There is no way to remotely change what’s printed on paper already in the wild - fixing a leak usually means printing new materials (or issuing a new tag/sticker with a new code).

QR stickers and NFC for quick care logging (at home)

Besides finder scenarios, you can place QR stickers (or use NFC taps) wherever a fast log is useful - same mental model as tapping the pet’s tag, but aimed at household and sitter workflows.

Typical uses:

• Stickers in the right spot - e.g. on the food bin, by the leash hook, near meds, or on a card you leave for a dog sitter. Scanning skips hunting through the app when hands are full.
• Same role as NFC for care - Both can open a FoundYa flow to record an activity (daily walks, fed, vaccines, medications, vet visits, and similar). NFC carries the link on the chip; QR carries it in the printed code.

Encoding the activity in the URL: A sticker or tag can point to a link that includes which activity in the query (or path) - for example walk vs fed vs medication. Then the person scanning does not need an extra step to select the activity; FoundYa can open the correct logging screen directly. That mirrors a generic tap that would otherwise ask “what are you logging?” first.

Choosing QR vs NFC for care stickers:

You can mix both: e.g. NFC on the collar for finders and QR stickers at home for care shortcuts - or two formats for the same pet so sitters can scan a sticker without touching the collar.

Rotating your link, exports, and who still has access

FoundYa is designed so your canonical link can be updated on NFC when you use link rotation in the app. You can also export a fresh QR image whenever your current link is valid - handy if you want a paper handout, a second sticker, or a disposable QR you give to a neighbour or sitter.

Ways to combine NFC and QR:

• NFC tag + printed QR - Keep the tag as the main “always correct” tap target after you rotate; re-print or re-export the QR artwork when you want paper to match (or keep a backup QR on packaging that you refresh at each print run).
• Two physical formats - e.g. one NFC on the collar and one printed QR on a card at home; rotate in the app and update the NFC first, then replace or re-export the printed side when you’re ready.
• A printed QR you gave someone - If you printed a QR from FoundYa and later rotate your pet’s public link, that old print stops working for the new link: anyone with only the old paper or photo loses access to your current profile URL (same idea as revoking an old link - they’d need your new export or your updated NFC tap).

Important: A static QR that you don’t control the artwork for (e.g. only printed on a factory collar tag you never reprint) behaves like any other frozen snapshot - social leaks may require new physical product to fully clear. NFC + ability to export an up-to-date QR gives you more control without always buying new hardware.

Using QR and NFC together

Many products use both: NFC for quick taps and a backup QR on the card or box for phones without NFC, when tapping isn’t convenient, or if the tag is damaged and no longer reads. Combining both also helps when you want to rotate your public link and re-issue fresh QR artwork while keeping a single updatable NFC tag.

Summary

If you’re unsure, both is a solid default for physical products: QR for maximum compatibility, NFC for the best “tap and help” experience - and you can add extra QR care stickers at home without replacing your main finder tag.
