"acceptedAnswer": {
"@type": "Answer",
"text": "No, it does not require any WordPress plugins. However, it relies on two external JavaScript libraries (qrcode.js and JsBarcode.js) which are loaded from a public CDN. This means the user's browser needs an active internet connection for the tool to function."

"acceptedAnswer": {
"@type": "Answer",
"text": "Error correction allows a QR code to be successfully scanned even if it's partially damaged or obscured. There are four levels: Low (L), Medium (M), Quartile (Q), and High (H), which can recover up to 7%, 15%, 25%, and 30% of damaged data, respectively. A higher level results in a denser QR code."

"acceptedAnswer": {
"@type": "Answer",
"text": "This usually happens if the content you entered is not valid for the selected barcode format. For example, the EAN-13 format requires exactly 12 or 13 digits and cannot contain letters. Check the requirements for the format you've selected and ensure your input is valid."
