A QR Code Nobody Can Ever Turn Off

How do you make a QR code that never expires?

1. Pick what the code should do. Choose website, phone call, text message, plain text, WiFi, or contact card. Each one writes a different kind of payload into the pattern.
2. Fill in the blanks. The code redraws as you type, on your device. Open the payload panel to see the exact string being encoded.
3. Style it if you want to. Set colors, add a logo, or turn on a frame with a call to action like SCAN FOR A FREE QUOTE. Watch the contrast readout.
4. Download the file you need. PNG at 512, 1024, or 2048 pixels for most jobs. SVG for the print shop. Or print a ready-made table tent, yard sign, decal, card back, or invoice insert.
5. Test it before you print 500 of them. Scan the code with two different phones from the real distance, then print one test page at final size and scan the paper.

What actually goes wrong with paid QR codes?

The failure isn't subtle. You print the code, the code stops resolving, and the printed thing is now garbage. That's the whole mechanism, and it isn't a rumor — the vendors document it.

QR Code Generator, the biggest name in the category and now owned by Bitly, publishes this in its own help center:

Read that twice. Downgrade and your customers watch an ad you didn't sell before they reach your own website. Cancel and the code dies. The same pattern shows up everywhere else in the category: QR Tiger deactivates dynamic codes past the free tier's 3-code limit when you cancel, and its free codes stop at 500 scans. Uniqode users describe printed packaging, signage and menus going dark immediately with no export and no legacy redirect.

Now put a dollar figure on it. Reprinting is the real bill. Wedding stationery runs $175 and up. A commercial product-label run is $5,000 to $40,000. One Egoditor customer, quoted in a March 2026 trade report, put it about as plainly as it can be put:

A Capterra reviewer of QR Code Generator said the same thing from the other end: had to "throw away all our collateral and print new — or pay them forever." That page sits at 3.3 out of 5 from 35 reviews, with customer service at 2.7. On Sitejabber the same domain scores 1.5 out of 5 across 349 reviews, with 12% of reviewers recommending it. The complaints are consistent: charges of $119.88 to $190 that people didn't expect, a 14-day trial they didn't notice starting, codes going dark mid-campaign, and no phone support at all.

What do QR code platforms cost in 2026?

Here's the market as published on the vendors' own pricing pages in August 2026. Note what you're actually buying: not "a QR code," but a monthly allowance of them.

The number worth staring at is Bitly's. Thirty-five dollars a month buys you ten QR codes. Not ten thousand scans of one code — ten codes, for that month. If you run six trucks, four yard signs, and a card back, you're over the limit in your first afternoon.

The QRCG per-seat figure comes from a competitor's teardown of the April 20, 2026 rebrand and is reported, not confirmed by the vendor.

What do the paid platforms do better than this page?

Four real things, and if you need any of them, go buy one. We'd rather say so than have you find out later.

• Change the destination after printing. That is the entire point of a dynamic code and it is genuinely useful. A seasonal promo URL, a menu that moves, a landing page you're still A/B testing — a static code can't do it. We can't fake it.
• Scan analytics. How many scans, when, roughly where, on what kind of device. A static code is invisible to us by design, which is the privacy benefit and the reporting cost in the same sentence. Half a workaround: point the code at a URL with a tracking parameter on the end, like ?src=truck, and read it in your own website analytics. That gets you counts without a subscription.
• Custom short domains and folders. If ten people at your company make codes and somebody needs to audit them, you want an account with permissions.
• GS1 Digital Link for retail packaging. If your product goes on a grocery shelf, there are standards coming that a general-purpose generator doesn't implement.

Is a free static code enough for your business?

For most service businesses, yes, and it's not close. Here's the test: will the destination ever change?

Your phone number won't. Your website address won't — and if it does, you've got bigger problems than the QR code. Your Google review link is permanent as long as your Business Profile exists. Your WiFi password changes maybe once a year, and reprinting a counter card costs about eleven cents. Your vCard changes when you change phones, which isn't a thing. Every one of those is a static code, forever, for free.

Where you'd want the paid version: you're printing 50,000 units of something, or you're running a marketing campaign where the landing page genuinely rotates, or you need to prove scan counts to somebody who signs checks. If you're a one-to-five person shop putting a code on a truck, an invoice, and a yard sign, you will never touch those cases, and paying $120 a year for the privilege of being able to have your sign switched off is a bad trade.

How big should a QR code be? The math, worked out

There's a rule of thumb and there's the actual arithmetic. Use the rule for sanity, the arithmetic when the job is expensive.

The rule: the code's printed width should be at least the scan distance divided by 10. Read from 10 inches, print at 1 inch. Read from 6 feet (72 inches), print at 7.2 inches. Read from 20 feet across a parking lot, print at 24 inches. That rule has slack built in, and the slack is what saves you when it's raining and the customer's phone is four years old.

The arithmetic: a scanner needs each individual square — each "module" — to land on enough camera pixels to be distinguished. The practical floor for a phone camera is roughly 0.4 mm per module in hand, more like 1 mm for anything read at distance or in bad light. So:

• A short URL at error correction M usually lands at version 3, which is 29 modules across, plus the mandatory 4-module quiet zone on each side, so 37 modules total.
• At 1 mm per module that's 37 mm, about 1.5 inches, and it will scan comfortably from arm's length.
• Push the same URL to error correction H and it grows to version 5, which is 37 modules plus quiet zone, 45 across. At the same physical size each module is now 0.82 mm instead of 1 mm. Higher error correction makes a code less scannable at a fixed size, not more. That's the tradeoff nobody mentions.
• A full vCard with name, company, phone, email and website runs 150 to 250 characters and typically lands at version 9 or 10 — 53 to 57 modules. That code needs about 2.5 inches to behave on a business card, which is most of the card. Shorten it or point the card at a URL instead.

The tool tells you the version and the module count under the preview, so you can check this yourself instead of guessing.

On DPI: 300 DPI is the print standard. The 1024px PNG divided by 300 is 3.41 inches. The 2048px file is 6.83 inches. Anything larger than that, use the SVG, because an SVG has no pixels to run out of — the printer's RIP renders it at whatever resolution the press wants. This is why print shops ask for vector, and why several QR platforms put vector export behind a paid tier.

Error correction levels, in plain English

Every QR code carries redundant data so it still reads when part of it is damaged. You pick how much.

The honest note about logos: the 30% figure is the decoder's total damage budget, and a centered logo spends most of it. Keep the logo under a quarter of the code's width, keep it truly centered, and never let it touch the three big squares in the corners — those are the finder patterns, and the scanner uses them to locate and orient the code before it reads anything. Cover a corner and there is no code, at any error correction level.

Color, contrast, and the mistakes that cost a reprint

Colored QR codes work. Colored QR codes also fail in ways that don't show up until the piece is printed and out in the world, so here are the rules the tool enforces for you.

• Dark code on a light background. Always. Inverted codes — light modules on dark — are technically decodable and a meaningful share of phone cameras won't bother. The contrast readout above turns red if you invert.
• Contrast ratio above about 4 to 1. Below that you're relying on good light and a good camera, which is not a plan. Black on white is 21 to 1. Navy on white is around 16 to 1. A mid-orange on white is about 3.5 to 1 and will disappoint you.
• Never put the code on a photo or a gradient. Solid background, full stop.
• Keep the quiet zone. Four modules of blank margin on every side. Designers crop it constantly because it looks like wasted space. It is not wasted space; it's how the scanner finds the edge.
• Watch out for gloss. A glossy laminate on a truck decal or a menu produces glare that wipes out a whole corner at the wrong angle. Matte finish scans better than gloss every time.
• Watch out for ink spread on cheap paper. A code that scans fine from a laser printer can smear on newsprint or a thermal receipt. Print bigger and bump error correction to Q for those.

Where a permanent code actually earns its keep

• Truck and trailer doors. A code plus "Scan for a free quote" at a red light. This is where an expiring code hurts most, because vinyl is expensive and getting it redone means the truck is off the road.
• Yard signs. You're working a house; the neighbors are watching. A code that opens a quote form beats a phone number, because nobody wants to make a call.
• Business card backs. Use contact-card mode so one scan saves your name, number and email. The card-back sheet on the print tab lays out ten at a time.
• Invoices and estimates. Point it at your review link, or at payment instructions. It costs nothing and it goes out with every job.
• Equipment stickers. Plain-text mode on the side of a furnace or water heater: model, serial, filter size, install date, your number. Two years later somebody scans it instead of calling the manufacturer.
• The shop WiFi. One code on the waiting-room wall and nobody asks for the password again.

Static or dynamic: how to tell which one you need

One question decides it. After this is printed, will the thing it points to ever move?

If no — phone number, website, review link, WiFi, contact card, equipment note — you want static, and static is free forever from this page. If yes, and you're confident enough about it to keep paying a subscription for as long as the printed piece exists, buy a dynamic code with your eyes open. Understand you're renting. Understand the code dies with the account. Understand that the day you decide the tool isn't worth $35 a month anymore is the day every piece of printed material you own becomes scrap.

There's also a middle path worth knowing about: point a static code at a page on your own website and put the redirect there. You get to change the destination whenever you like by editing your own site, you keep the analytics in your own analytics, and nobody can turn it off but you. That's the setup we'd recommend to any business that owns its site — and it's free.
