A static or dynamic QR code linked to a hosted checkout page can be applied as a sticker or printed insert to most existing machines. The payment authorization is handled by the gateway's backend, which communicates with the machine's cashless interface to trigger the vend. This makes QR a relatively low-cost upgrade compared to installing a new card reader.","inLanguage":"cs"},"inLanguage":"cs"},{"@type":"Question","@id":"https:\/\/pageloot.com\/id\/qr-codes-for\/vending-machines\/#faq-question-91963ddcecbe","position":3,"url":"https:\/\/pageloot.com\/id\/qr-codes-for\/vending-machines\/#faq-question-91963ddcecbe","name":"Co se stane, pokud n\u011bkdo zakryje m\u016fj QR k\u00f3d podvodn\u00fdm?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"A customer who scans the fraudulent code will be redirected to a different page rather than your checkout.

Dynamic QR code analytics can also help: if scans suddenly drop to zero or originate from unexpected locations, that's a signal to investigate the physical code at that machine.","inLanguage":"cs"},"inLanguage":"cs"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/55467","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/comments?post=55467"}],"version-history":[{"count":1,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/55467\/revisions"}],"predecessor-version":[{"id":55536,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/55467\/revisions\/55536"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/media\/55344"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/media?parent=55467"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/categories?post=55467"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/tags?post=55467"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
