WOW 🚨 Pay Attention To Canada Because America Is Next. QR Codes To Visit & Leave Areas Quebec: “Madeleine Island getting QR codes in order to leave and If you don't get your QR code, you will be fined” “That's the very first QR code prison here in Canada. And it is going to sweep the nation faster than you can think if people don't stand up and take a stand against these QR codes.” “It's not happening in your town yet but it most certainly will be.” “We know the government's expropriating land from farmers all over the place. We know that they are trying to make military presence and normality, so it's only a matter of time before you are trading away your information, your private information in a QR code in order to leave your town or city so that you can go to work, shop, get an education, or just plan out, visit, and travel this amazing country. Time to stand up and wake up and use your voice.”

WATCH: Some overseas Filipinos who took part in the first-ever online voting have raised concerns after the QR code scanned for vote verification did not display the names of candidates they selected. Comelec Chairman George Garcia clarifies that the QR code only confirms that the vote was successfully cast. The information is encrypted to prevent it from being used as a receipt in cases of vote buying, he says | Eimor Santos #VoteWatch #Eleksyon2025

The new Screenshot to Code from Vercel v0 is insane. I just took a screenshot of a pricing table and it was converted into code using AI in seconds! It even outputs the code and allows you to modify any specific parts.
