Are you in a restaurant and you cannot access the menu because your mobile hasn’t got a QR scanner? You might also need to scan the QR code to get Wicodes, download articles, etc… but you don’t have a QR scanner on your phone.
You can easily resolve the issue by getting a QR scanner on Google Play. There are a number of apps.
I have a SAMSUNG J4 (entry level) and I did not have an in-built QR scanner. Went to Google Play and tried a few. If you are looking for a fast, reliable QR scanner I recommend ‘QR & Barcode Scanner’ by Gamma Play.
My review on Google:
Amazing experience. Super fast to install and works perfectly. This is a free App. Some other free QR free Apps request one’s credit card details to “verify” your location. Not this one. I am glad I found ‘QR Code Scanner’. Highly recommended👏👍👌
