This Is probably a stupid question but I need to ask, is there any risk to scan a barcode at store or anywhere to use crypto wallet to make payment?
For fiat transactions, we can easily find this for several banks and currently their customers can use Quick Response Code or QR Code technology for transactions. Indeed there are vulnerabilities as well and technically the QR Code can be replaced and faked but for that only one confirmation is it true that you want to transfer it to this name?
The main problem is that QR codes are difficult to distinguish genuine from fake by the human eye.
Well, for QR Code transactions using a crypto wallet to make payments is not much different, I think only if you do the suggestion only for small transactions and use an alternative wallet, not the main asset wallet when you shop at trade outlets that facilitate this. True, OP learned from the example of the case in China at the end of 2017 which cost consumers more than US$13 million caused by QR code fraud.
