QR codes in Mobile phone presentations for mobile phone users is stupid beyond stupid. Universal Resource Locators solved the problems for hypertext documents in the 1990s. QR codes solved the problems where hypertext could not communicate across an air gapped presentation. The Scan Cat was one way to take magazine advertisements or articles into the Web.
Now retards are sending QR codes as messages too convolute the simple presentation of data within the digital realm.
I'm just laughing. 😂
