How to Make a Wi-Fi QR Code for Your Shop or Office in India

The short answer

No Indian statute, rule or regulator order governs how a Wi-Fi QR code is built, so this guide has no statutory section to cite. The rules that matter are technical. The code must carry the same network name, security type and password as your router, and it keeps working only while those settings stay the same. A Wi-Fi QR code is a static image. It is not linked to your router, so it cannot update itself.

Most of the work is a five-minute task: gather the three settings, generate the code, test it, and size the printed card for the place where people will scan it. The sections below walk through each step, then cover the cases that change the answer, such as a changed password, an office network with individual logins, or an older router.

What the code actually contains

A Wi-Fi QR code is an ordinary QR code whose content is a short line of plain text. Phone cameras read that text and offer to join the network. The common layout looks like this: WIFI:T:WPA;S:NetworkName;P:password;H:false;; The letter T gives the security type, S is the network name (the SSID), P is the password, and H says whether the network is hidden. Two semicolons close the string.

For the security type, WPA is the value most generators use for WPA, WPA2 and WPA3 networks, because the phone negotiates the exact protocol with the router. WEP is an old value for very old routers. The value nopass is used for open networks with no password. Some generators label the newer standard as SAE, which is the same family. You do not need to write this string yourself. The generator builds it from the form fields, but knowing the layout helps you spot a mistake when a code fails.

Step by step with the tool

1. Find the exact network name. Open the router's admin page or the Wi-Fi list on a phone that is already connected. Names are case-sensitive, so capitals, spaces and symbols all matter. Copy the name rather than retyping it.
2. Check the security type on the router. Log in to the router's admin page and look at the wireless security setting. WPA2 AES and WPA3 Personal are the strong choices. If the router shows WEP, plan to upgrade the router before you rely on a public code.
3. Enter the password exactly as the router stores it. Check every character, including zeros and capital O, and any symbols. Do not use the password of a staff login or a billing system.
4. Tick the hidden network box only if the Wi-Fi name does not appear in the phone's list. Most shop and office networks broadcast their name, so this box is usually left off.
5. Generate the code and download it. Choose an SVG or high-resolution PNG for print. A low-resolution image can blur when enlarged on a card.
6. Test it. Scan the code with at least one Android phone and one iPhone, while connected to a different network or with Wi-Fi switched off, and confirm the phone joins. Test it at the distance where a customer would hold the phone.

Some generators say they build the code inside your browser, so the password is not sent to a server. Before you enter a real password, check that claim on the tool's own privacy page, and do not rely on a verbal assurance from a reseller.

Sizing the printed card for a counter

The size of the printed code depends on how far away people will scan it. A widely repeated rule of thumb in QR printing guides published in 2026 is the 10:1 rule: the code should be at least one-tenth as wide as the scanning distance. It is a rule of thumb rather than a formal standard, so test the printed card at the real distance before you order a large run. Most guides also set an absolute floor of about 2 cm for close-range scanning.

The margin column adds room for poor light, a glossy laminate that reflects lamps, and older phone cameras. Keep a clear border of blank space around the code, and do not place a logo or text that cuts into that border. Laminate a counter card, because a card that gets wiped, folded or stained is the most common reason a code stops scanning in daily use.

Worked example: a counter card in a Pune shop

Take a small shop in Pune with a router set to WPA2 AES. The guest network name is ShopGuest_5G, the password is eleven characters long, and the hidden box is left unticked. The owner wants a stand on the billing counter, where customers hold their phones about 30 cm from the code.

The calculation is short. A 30 cm scanning distance divided by 10 gives 3 cm, which is the minimum width. Adding a 30 percent margin gives 3.9 cm. The owner rounds up and prints a 4 cm square on an A6 card, leaving a white border around it, and laminates the card. The generator produces an SVG file, the print shop prints at 4 cm, and the owner checks the printed card with one Android phone and one iPhone at the counter.

Two things follow from this setup. First, the printed card is only as good as the password at the time it was printed. Second, the card should sit on a guest network, not on the network the shop uses for billing or point-of-sale machines. The example uses illustrative names. Replace them with your own router details.

Cases that change the answer

The biggest change comes when the password changes. Because the password is written into the code, the printed card stops connecting people as soon as the router password is changed. The fix is to generate a new code, print a new card, replace the old one, and test it again. Keep one master settings sheet with the network name, security type and password date, so the person who replaces the card knows which version is current.

Staff turnover also matters. Anyone who scans the code can read the password with an ordinary QR reader app, so a code on a public counter is effectively a public password. If you want staff to leave the network when they leave the business, keep staff devices on a separate network and use the public code only on the guest network.

Router age changes the choice of security type. Many routers can run WPA2 and WPA3 together in a mixed mode, which lets newer phones use the stronger standard while older phones still connect. The Wi-Fi Alliance introduced WPA3 in 2018, so a router bought before that may only support WPA2. If the router supports only WEP, it is too old for a public code, and the router should be replaced before the card is printed.

Some offices do not fit this tool at all. Networks that give each person an individual login, usually through 802.1X certificates or a RADIUS server, do not use a shared password. A Wi-Fi QR code carries a shared password, so it does not suit those networks. Check with the IT provider before printing a code for an office of that kind.

A code also does not get past login pages. Some guest networks show a splash page where guests accept terms or enter a phone number before the internet works. The QR code joins the network, but the guest still has to complete the splash page.

Common mistakes

The most common mistake is a wrong network name. A single extra space or a lower-case letter where the router has a capital will make the phone join a different network, or none at all. The second is the security type. Choosing WPA for a network that uses WEP, or choosing nopass for a network that has a password, produces a code that fails without an obvious error message.

Printing without testing is the third mistake. Many owners print 50 cards and then find that a particular phone model refuses to join. Test on at least two phone types, and test at the distance the customer will use. The fourth mistake is printing too small. A 2 cm code can work for a business card held in the hand, but it is unreliable on a counter stand, and the margin in the table above is there for a reason.

The last mistake is forgetting the password change. Many shops replace a code only after a customer complains. A dated settings sheet and a fixed reminder to test the card after every router change prevent that.

What to check before you print

• Confirm the network name, security type and password with whoever manages the router, such as the broadband provider, landlord's IT contact or an outside IT firm.
• Confirm that the public code uses a guest network that has no access to billing, point-of-sale or staff files.
• Name one person who will generate a new code and reprint the card after any password change, and write down the date.
• Test the printed card on an Android phone and an iPhone at the real scanning distance.
• Check with the IT provider if your office network uses individual logins, because a shared-password code will not fit that setup.

Where routine HR and payroll work fits

Employers in India often run HR and payroll on several spreadsheets, a biometric attendance export and a set of follow-up emails. Much of that work is routine: matching attendance entries to a register, chasing missing documents, preparing monthly reports and checking that the same figures appear in each file. AiStaffo builds AI workers that take this kind of work off staff, so the people in HR and payroll spend their time on exceptions and approvals. A person still approves each payroll run and decides on anything unusual, and the results depend on the reader's own records, which the free audit measures.
