QR stickers on your things

A QR sticker is a durable label with a QR code that you attach to an item (car, pet, keys, luggage, bike). Whoever finds the item — or wants to reach you about it — scans the code and lands in a conversation with you, without installing the app and without either side revealing a phone number, name or address.

QR stickers are available only from age 18: someone under 18 can neither create a sticker nor message someone through theirs. This is how Tacq protects teenagers from strangers.

Two main scenarios:

• Lost & found. A tag on a pet’s collar, keys or a suitcase — the finder messages the owner.
• Anti-parking. A sticker on a windshield: “Did I box you in? Scan — I’ll reply or come down.” You stay reachable without a number on the glass.

Creating a sticker

1. Menu → QR Stickers → Create sticker.
2. Pick the item type (car / pet / keys / luggage / bike / generic) — it sets the icon and a default greeting.
3. Set a label — only you see it, to tell your stickers apart (“My car”, “Rex’s collar”).
4. Optionally edit the greeting to the finder — the text the scanner will see.
5. Save. The sticker is ready.

Printing

Open the sticker → Print:

• Single sticker — one large label.
• A4 sheet — eight identical stickers to keep in reserve (for keys, a backpack, an umbrella).

The QR is printed with extra resistance to dirt and wear. Tip: laminate the sticker or cover it with clear tape to protect it from water. The printed sticker shows your greeting and the Tacq logo.

Keep the printed greeting in one language. Mixing, say, English and Hebrew in one text prints poorly — the languages run in different directions.

You can also Show QR on screen (for a quick scan from another phone) or Share the link.

What the finder sees

After scanning, the person lands on a page with a large icon of the item type (car, pet, keys…) at the top and your greeting below. They can message or call you right away, as a guest, with no sign-up. Their number and details stay private from you, and yours from them. To receive replies even after closing the tab, they’re invited to save their account.

Your sessions per sticker

Every new finder is a separate session (finders never see each other). Sticker sessions are not shown in the Private tab: they are grouped in the QR Stickers tab on the home screen, with each sticker’s sessions listed under it. The tab appears by itself when someone writes to you via a sticker, and you can also open it with the “QR Stickers” menu item. Which tabs to show is set in Settings → Home screen tabs.

When someone writes to you via a sticker, it is usually urgent. So when you open the app, you will immediately see the window “Someone wrote to you via your QR sticker” with a button that takes you to the session. Until you open the session, a red dot stays on the menu button, on the “QR Stickers” item and on the sticker itself. If notifications are allowed, you will also get a notification on your phone.

If you are offline, the finder sees an auto-reply. You can write your own text in the sticker, in the “Auto-reply when you are offline” field, for example: “I’ll be there in 5 minutes”. If you leave it empty, the finder sees that you are offline and that their message has been delivered.

Managing a sticker

Tap a sticker to open its card with the QR code. In the card:

• Pause / Resume — temporarily stop accepting new finders (e.g., car in the garage). Existing chats stay.
• Reissue — if the QR is compromised (photographed, spammed) or the item is sold: the old code stops working and a new one is generated — print and replace the label.
• Delete — remove the sticker.
• Emergency mode — quickly restrict a shared-around QR: Text only mutes calls for everyone on the sticker; Freeze pauses it.
• Block a chat with one person without touching the sticker — new finders can still message you.

Privacy

Neither you nor the finder reveals a phone number, email, name or address. The app does not share your location. If a finder wants to send where they left the item, that is their deliberate action, not automatic.
