Question 1

What data types can I encode in a QR code?

Accepted Answer

You can encode various data types, including URLs, plain text, contact information (vCard), Wi-Fi credentials, email addresses, phone numbers, SMS messages, and much more.

Question 2

What is the maximum amount of data a QR code can store?

Accepted Answer

QR codes can store up to 4296 alphanumeric characters, 7089 numeric characters, or 2953 bytes of binary data. However, the more data you include, the denser and harder to scan the code becomes.

Question 3

Can I customize the appearance of my QR code?

Accepted Answer

Yes, you can customize colors, add logos, change module shape, and adjust the error correction level. However, ensure sufficient contrast between foreground and background for reliable scanning.

Question 4

What is the best size for printing QR codes?

Accepted Answer

The minimum recommended size is 2x2 cm (0.8x0.8 inches) for close-range scanning. For long-distance scanning, use larger sizes. A rule of thumb: scanning distance = QR code size × 10.

Question 5

Why might my QR code not scan correctly?

Accepted Answer

Common issues include insufficient contrast, too much or too little data, poor print quality, damaged code, or inadequate lighting. Ensure good contrast, test before mass printing, and include error correction.

Question 6

What is error correction in QR codes?

Accepted Answer

Error correction allows QR codes to be readable even if partially damaged. There are four error correction levels (L, M, Q, H), where H provides the most redundancy (up to 30% damage).

Question 7

Can I create dynamic QR codes?

Accepted Answer

Our generator creates static QR codes. Dynamic QR codes (which allow content to be changed without creating a new code) require a third-party service that stores the actual link and redirects the user.

Question 8

Are QR codes secure?

Accepted Answer

The QR code itself is just a data format. Security depends on the encoded content. Be cautious when scanning codes from unknown sources, as they may lead to malicious websites or unwanted content.
