Because the malicious URL is embedded in an image, it often bypasses email security filters that would normally catch suspicious links in plain text. The outcome is the same \u2013 stolen credentials, payment details, or malware installation \u2013 but the delivery method makes it harder for both automated tools and users to detect.","inLanguage":"cs"},"inLanguage":"cs"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/how-to-protect-your-business-from-qr-code-scams\/#faq-question-e82de4ac3422","position":2,"url":"https:\/\/pageloot.com\/blog\/how-to-protect-your-business-from-qr-code-scams\/#faq-question-e82de4ac3422","name":"Jak pozn\u00e1m, zda byl QR k\u00f3d pozm\u011bn\u011bn?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Look for physical signs such as stickers placed over existing codes, misalignment, scratches, or pixelation.

Be especially suspicious of codes accompanied by urgent language or in unusual locations without a clear explanation.
