QR code (WhatsApp, Google review)
A QR code (Quick Response Code) is a two-dimensional barcode that triggers an action when scanned with a smartphone – such as opening a WhatsApp chat or directly accessing a Google review page. In modern marketing, QR codes are one of the simplest bridges between the physical and digital worlds. hellomateo enables the generation of QR codes directly from the platform – for WhatsApp opt-in campaigns, Google review requests, and more.

A QR code can be scanned in seconds and takes the user directly to the desired action without any typing. For businesses, it's a versatile tool that connects online and offline marketing. QR Code for WhatsApp Opt-in: A QR code can be configured so that scanning it directly opens a WhatsApp chat with the company – and optionally sends a pre-filled opt-in message. This allows companies to collect WhatsApp subscribers at the checkout, on packaging, in print ads, or at trade fairs. hellomateo generates these QR codes directly from the platform and links them to the desired opt-in flow. QR Code for Google Reviews: A QR code that leads directly to the Google review page significantly lowers the barrier to entry for customers: Instead of searching for a long time, a scan is all it takes. Placed at the checkout, on receipts, table displays, or packaging, it significantly increases the rating rate.
