How to Use QR Codes (They're Everywhere Now)

QR codes are those square black-and-white patterns you see everywhere — restaurants, stores, parking meters, TV ads. Here's how to scan them safely with your phone, what happens when you do, and how to make your own.

At a Glance

What is a QR code?

~2 min

A QR code — short for "Quick Response" code — is a small square image made up of black and white dots arranged in a pattern. Think of it as a shortcut. Instead of typing a long website address into your phone, you just point your camera at the code and your phone reads it instantly. QR codes were invented in 1994 in Japan to track car parts in factories, but they have exploded in everyday use since 2020. The COVID-19 pandemic made them popular at restaurants as a contactless way to view menus, and now they are used for just about everything — paying for parking, checking into appointments, sharing WiFi passwords, and more. Each QR code contains a specific piece of information, usually a website address (URL). When your phone reads the code, it shows you that information and asks if you want to open it. The code itself does not do anything without your permission — you always get to decide whether to follow the link.

Quick Tip

QR codes can hold different types of information — not just website links. Some contain phone numbers, WiFi network passwords, email addresses, or even plain text messages. Your phone will show you what the code contains before you take any action.

Where you will find QR codes

~2 min

QR codes are now part of daily life. Here are the most common places you will see them: Restaurants — Many restaurants replaced paper menus with QR codes printed on table tents or stickers. Scan the code and the menu opens on your phone. Stores and shopping — Product tags, sale signs, and store windows often have QR codes that take you to product details, reviews, or special offers. Parking meters and transit — Modern parking meters have QR codes that let you pay from your phone instead of feeding coins. Bus stops and train stations use them for schedules and fare information. Business cards — Instead of typing in someone's contact information, you can scan a QR code on their card and it saves their name, phone number, and email to your contacts automatically. TV commercials and magazine ads — Advertisers put QR codes on screen so you can scan them to visit a website, download an app, or get a discount code. Doctor's offices and hospitals — Many medical offices use QR codes for check-in, patient forms, and appointment scheduling. Event tickets — Concert tickets, boarding passes, and museum entries increasingly use QR codes instead of paper tickets. The scanner at the door reads the code on your phone screen.

How to scan a QR code with an iPhone

~2 min

If you have an iPhone running iOS 18 or iOS 19 (the current May 2026 release), scanning is built right into the Camera app — no extra app needed. (This has worked on every iPhone going back to iOS 17, so almost any iPhone made in the last five years supports it.) Open the Camera app on your iPhone — the same app you use to take photos. Point the camera at the QR code so the entire square is visible on your screen. You do not need to take a photo. Hold your phone steady for a second or two. A small notification banner will appear at the top of your screen showing the website address or action the QR code contains. Tap that banner to open it. That is all there is to it — three steps: open camera, point, tap. If the banner does not appear, make sure QR code scanning is turned on. Go to Settings, then Camera, and check that "Scan QR Codes" is toggled on (it should be green).

Quick Tip

You can also scan QR codes from the Control Center. Swipe down from the top-right corner of your screen and tap the QR code icon (a small square with dots) if it appears. This opens a dedicated scanner that works in low light.

How to scan a QR code with an Android phone

~2 min

Most Android phones made after 2018 can scan QR codes directly through the Camera app, just like the iPhone. Open the Camera app on your Android phone. Point it at the QR code and hold steady. A link or notification will appear on your screen — tap it to open. If your Camera app does not scan QR codes automatically, you have two easy alternatives. First, try Google Lens — open the Google app on your phone, tap the camera icon (or the Google Lens icon, which looks like a small colorful camera), and point it at the QR code. Second, on Samsung phones, you can swipe down from the top of the screen to open Quick Settings and tap the "Scan QR code" tile. If none of these options work on your phone, you can download a free QR scanner app from the Google Play Store. Search for "QR code scanner" and choose one with high ratings and many downloads — "Google Lens" by Google is a safe and reliable choice.

Quick Tip

Google Lens can do much more than scan QR codes — it can also identify plants, translate text in photos, and look up products. It is a handy app to have on any Android phone.

What happens when you scan a QR code

~2 min

When you scan a QR code, your phone reads the information stored in the pattern and shows you what it found. In most cases, it shows a website address and asks if you want to open it. Here is what to expect in different situations: Restaurant menu — Your phone opens a webpage showing the restaurant's menu. You can scroll through it, zoom in, and browse just like any website. Payment — The code opens a payment page where you enter your amount or confirm a purchase. You are not charged anything just by scanning — you have to actively complete the payment. WiFi — Some QR codes connect you to a WiFi network automatically. Your phone will ask you to confirm before connecting. Contact information — The code may offer to add someone's name, phone number, and email to your contacts. You tap "Add" to save it. App download — Some codes take you to the App Store or Google Play Store to download an app. Nothing installs automatically — you still have to tap "Download" or "Install." The most important thing to remember: scanning a QR code does not automatically do anything dangerous. It shows you information, and you choose what to do next. You always have a chance to review before tapping.

Safety tips for scanning QR codes

~2 min

QR codes are generally safe, but there are a few things to be aware of — just like you would be careful about which links you click in an email. Do not scan random QR codes — If you see a QR code taped to a random pole, stuck on a public wall, or left on a flyer in a parking lot with no clear source, skip it. Scammers sometimes place QR codes in public places that lead to fake websites designed to steal your information. Check the URL before tapping — When your phone shows the link from a QR code, look at it before you tap. Does it match what you expect? A QR code at a restaurant should go to that restaurant's website, not a random string of characters or a completely different website. If the URL looks suspicious or unfamiliar, do not tap it. Beware of stickers placed over real codes — One common scam involves placing a fake QR code sticker over a legitimate one. This happens at parking meters, restaurant tables, and public payment kiosks. If a QR code looks like it was stuck on top of something else, or if the sticker is crooked or peeling, be cautious. When in doubt, ask a staff member or find another way to pay. Never enter passwords or sensitive information on a page you reached through a QR code — If scanning a QR code takes you to a page asking for your bank login, Social Security number, or other sensitive details, close the page immediately. Legitimate businesses do not use QR codes to collect this kind of information. Keep your phone updated — Software updates include security fixes that help protect you from malicious websites. Make sure your iPhone or Android phone is running the latest version of its operating system.

Warning

In 2024 and 2025, the FTC reported a rise in QR code scams at parking meters and public payment stations. Scammers place fake QR code stickers over the real ones, redirecting your payment to their account. If a parking meter has a QR code, check that it looks original — not a sticker placed on top — or use the meter's coin slot or official app instead.

How to create your own QR code

~2 min

Making your own QR code is free and surprisingly easy. You might want one to share your WiFi password with guests, put your contact info on a business card, or share a link with someone. To share your WiFi password: On iPhone, go to Settings, then WiFi, tap the blue "i" icon next to your connected network, and tap "QR Code" — guests can scan it to connect instantly. On Android, go to Settings, then Network and Internet (or Connections), tap WiFi, tap your connected network, and look for a "Share" or "QR Code" button. To create a QR code for a website, contact info, or text: Open a browser and go to a free QR code generator website. Reliable options include qr-code-generator.com and the-qrcode-generator.com. Type in the website address, text, or contact information you want to share, and the site generates a QR code image you can download and print. To use Google Chrome's built-in QR code maker: If you are on a computer using Google Chrome, go to any website, click the share icon in the address bar (or right-click the page and select "Create QR Code"), and Chrome generates a QR code for that page. You can download and share the image.

Quick Tip

If you run a small business or community group, a free QR code linking to your website or sign-up form makes it easy for people to find you. Print it on flyers, business cards, or even a T-shirt.

QR codes for payments

~2 min

QR codes have become a popular way to pay for things, especially at farmers markets, small businesses, food trucks, and charity events. Venmo, PayPal, and Cash App — If someone asks you to "scan to pay," they are usually showing you a QR code linked to their Venmo, PayPal, or Cash App account. Open the payment app on your phone, tap the scan icon (usually looks like a camera or QR code symbol), point it at their code, enter the amount, and confirm. The money goes directly to them. Apple Pay and Google Pay — Some stores have QR codes at the register instead of tap-to-pay terminals. If you have Apple Pay or Google Pay set up on your phone, you can scan the store's QR code to pay. The store's payment system tells your phone the amount, and you confirm with Face ID, fingerprint, or your passcode. Parking and transit — Many cities now use QR codes on parking meters and transit stations. Scan the code, enter your license plate or transit details, and pay right from your phone. The same safety rules apply: only scan QR codes from sources you trust, check that the payment amount looks correct before confirming, and never send money to someone you do not know based on a random QR code.

Quick Tip

At farmers markets or small vendor booths, it is normal to pay by scanning a QR code linked to Venmo or similar apps. Make sure the name that appears in the app matches the vendor you are paying — this confirms the code belongs to the right person.

Troubleshooting: QR code won't scan

~2 min

If a QR code is not scanning, try these fixes one at a time: Clean your camera lens — A smudged or dirty lens is the most common reason for scanning problems. Wipe the camera lens on the back of your phone gently with a soft cloth or your shirt. Improve the lighting — QR codes are hard to read in dim light. Move to a brighter area, turn on a nearby light, or use your phone's flashlight. In the Camera app, you can usually turn on the flash by tapping the lightning bolt icon. Hold steady and get the right distance — Hold your phone about 6 to 10 inches from the code and keep it steady. If you are too close, too far, or moving too much, the camera cannot focus on the pattern. Make sure the entire QR code is visible on your screen. Check for damage — If the QR code is torn, faded, wrinkled, or partially covered, it may not scan. QR codes have some built-in error correction (they can still work even if part of the code is damaged), but heavy damage will prevent scanning. Ask for a new copy or try a different code if one is available. Restart your camera app — Close the Camera app completely and reopen it. On iPhone, swipe up from the bottom of the screen (or double-press the Home button) to see your open apps, then swipe the Camera app up to close it. On Android, tap the square button at the bottom to see recent apps, then swipe the Camera away. Check your settings — On iPhone, go to Settings, then Camera, and make sure "Scan QR Codes" is turned on. On Android, open the Camera app, tap the gear icon for settings, and look for a QR code scanning option. If nothing works, you can always type the URL or information manually. Ask the person or business for the web address the QR code points to and enter it in your browser yourself.

Quick Tip

If you wear reading glasses, you may find it easier to scan QR codes while wearing them — it helps you position your phone at the right distance and angle.

You have probably noticed those small square patterns made of black and white dots showing up everywhere — on restaurant tables, store windows, parking meters, business cards, and even during TV commercials. Those are QR codes, and they are one of the simplest and most useful tools in everyday life once you know how they work.

A QR code is like a barcode, but instead of the straight lines you see on a cereal box, it uses a square pattern of tiny dots. Your phone's camera can read this pattern instantly and take you to a website, a menu, a payment page, or just about anything else.

The good news is that scanning a QR code takes about two seconds and requires no special app on most modern phones. This guide walks you through everything: what QR codes are, where you will find them, how to scan them on iPhone and Android, what to expect when you do, how to stay safe, and even how to create your own.
