They reach you.
You keep your number.
Put the card on your dashboard. Whoever needs the car moved scans the QR and writes to you in one tap. You get an email, you answer from your phone, and your number stays yours unless you decide to share it.
Scan to message the owner
A phone number written on cardboard is not a plan.
Every driver has done one of these. None of them work well, and two of them hand your number to a stranger.
- 01 You blocked someone in. They wait, they knock on the wrong door, or they leave angry.
- 02 You left the lights on, or a window open before the rain. Nobody has a way to tell you.
- 03 You wrote your number on the windshield. Now anyone who walks past has it, forever.
Scratch, set it up once, done.
The whole thing takes about a minute, and you never make an account.

Scratch the panel
Under it is your Owner Access Code, printed only on your card. It is the one thing that proves the card is yours, so keep it the way you keep a key.
Tell it about the car
Your car, the name you want shown, a short message, and the email where alerts should land. Pick a style for your page while you are there.
Leave it on the dashboard
The QR on the card never changes and never expires. Change your message, your car or your alert email whenever you like, and the printed card keeps working.
They tap a reason and send.The email lands with you.You answer. They see it where they are.
What the other person sees.
They point a camera at the card. No app, no sign up, no code to type. They tap the reason and send.
One tap is a whole message
The common reasons are buttons, so a person in a hurry sends something useful without typing a word. They can still write freely if they want to.
Then it becomes a conversation
Your reply opens a live thread on the same page they are already looking at, so "two minutes" actually reaches them.
They see a number only if you show one
Out of the box: no phone, no email, nothing to copy down. The page carries your message and a way to write to you, and that is all it carries. Adding a WhatsApp button is yours to switch on, and off.
Your side of it.
An email, the moment it happens
Every message goes to the address you typed during setup, and only there. If you change the address later, the next alert follows it.
Answer from any phone
Open your card, read the thread, reply. Nothing to install, and no password to remember beyond the code on the card.
Change your mind freely
A new message, a different car, another email, a different look for the page. Edit as often as you like; the printed QR is unaffected.
Choose how the page looks
Pick a style during setup and see it rendered before you keep it, so the page a stranger opens looks like something you chose.
Pick how your page looks.
A style is not a colour swap. Each one changes the material of the page: how the surface is made, how the facts are grouped, what the type sounds like. Choose during setup, see it rendered before you keep it, and change it later whenever you like.

What never happens.
A card on a dashboard is read by strangers all day. It is worth being exact about what it gives away.
- We never require a phone number. The card works end to end without one, and nothing asks you for it. If you add a WhatsApp number yourself, it is shown only while you keep that button switched on, and we never sell it or market to it.
- Neither of you creates an account. No password, no profile, no marketing list.
- Your Owner Access Code never appears in a link, so a shared URL can never carry it.
- Someone scanning your card is never asked for the code, and never sees that one exists.
- We send no SMS and use no one-time codes, so nothing arrives on your phone bill.
And if someone guesses at the code
Guessing is rate limited four separate ways, and a card that is being attacked locks for at most an hour, never longer. That cap is deliberate: an attacker must never be able to lock you out of your own card.
What arrives.
A printed card, cut and finished, with the QR and the code produced together in the same pass so the pair on your card can never be someone else’s.
A permanent QR
Printed once, valid for the life of the card. It is the public side, and it is the only side a stranger ever touches.
A scratch panel
Physically one-time. Intact means nobody has read the code, which is how you can tell a card is untouched before you take it.
A code that lasts
It is not spent when you set the card up. You need it again to edit your message next year, so it stays valid for as long as the card does.
Straight answers.
Does the person scanning need an app?
No. Any phone camera opens the page in the browser. There is nothing to install and nothing to sign up for, on either side.
Do I need a Qrindo account?
No. The code printed on your card is how you get in. That is the whole design: a card should work for someone who will never open a dashboard.
What if I lose the code?
You need a replacement card. We keep no copy that can be sent back to you, and there is no reset link, because any recovery path is also a way in for someone else. Photograph the panel once you scratch it.
Can they message me on WhatsApp?
Only if you switch it on. In your card settings you can add a WhatsApp number and tick a box, and a WhatsApp button appears beside the private message form. It stays off until you do both, and you can turn it off again whenever you like. Opening a WhatsApp chat does show the other person your number, so it is a trade: faster for them, less private for you.
Can someone else take over my card?
They would need the printed code. It never travels in a link, the page a stranger sees never mentions it, and guessing runs into four separate limits.
What shows up before I set it up?
A page that says the card is not set up yet, with a way for its owner to enter the code. Nothing about a car, because there is nothing yet.
Can I get them for a fleet or to resell?
Yes, cards are produced in runs. Write to us with how many you need and what you want printed on them.
