This is almost always Android battery management freezing the app while the phone is idle. Open QRSprint, go to Profile, then Notifications, then Call Reliability. That screen checks every setting a call depends on and tells you which one is blocking it.

The setting that matters most is battery use. On most phones it is under Settings, Apps, QRSprint, Battery, and it must be set to Unrestricted. On Samsung, also check that QRSprint is not listed under Settings, Battery, Background usage limits.

Open the tag in the app and check that Tag active is on, and that Silence calls is off. A tag that has been paused still shows your profile but will not ring your phone.

Scan the QR on it with your phone camera, or type the short link printed next to it into a browser. The page that opens asks you to sign in and then for the claim code, which is on the small card that came in the box, never on the tag or standee itself. Enter it, give the item a name, and it is yours.

Most plans, including Smart Tags, Door Tags and Dynamic QR, are billed yearly, so access continues while the plan is current. A few physical accessories are a single payment. The price and billing period for each one are shown on its checkout page. Whatever happens to the plan, the printed QR pattern never changes, so you never reprint or relabel.

That page is what a standee shows before anyone claims it, and also right after a claim if the owner has not chosen a destination. If you are the owner, sign in at qrsprint.com/dashboard/qr, open your standee, and set the destination under Edit. The next scan goes straight there.

If you were just scanning somebody's standee, nothing is broken. Its owner has not finished setting it up.

Three ways, and they all show the same numbers:

• In the app, on the tag or QR itself.
• On the web at qrsprint.com/dashboard, signed in with the same account.
• Through the private link printed on the card in your box. It needs no app and no account: open it and you see scans, calls, messages, the last 30 days, and where people scanned from.

Keep that printed link private. Anyone who opens it can read the same page, so treat it like the card it came on.

Capitals and spaces do not matter, so abcd 2345 and ABCD-2345 are the same code. Check for a zero typed as the letter O: the codes never contain O, I, 0 or 1 for exactly that reason. After several wrong tries the page pauses you for a minute.

If the code is right and it still refuses, email us the code printed on the item itself and we will look it up.

Email founders@qrsprint.com with the short code printed on the item. We can return it to stock so you can claim it with your own code, and whoever claimed it loses access. Older items shipped without a claim code and could be claimed by anyone who scanned them first, which is what this usually is.

Sign in on the new phone with the same account and your tags come with you. Nothing is stored on the device itself. If you cannot get into the account, email us from the address you signed up with.

Deleting a tag in the app immediately wipes its profile, contacts and scan history. To delete your whole account, open Profile in the app and tap Delete account, or email founders@qrsprint.com from the address you signed in with and we do it within 48 hours. What exactly gets deleted. See our Privacy Policy for what we hold and why.

The app is free and sells nothing. Everything is bought either on qrsprint.com or from a marketplace listing, so refunds come to us or to that marketplace. Email founders@qrsprint.com with your order and we will sort it out.
