QR code scams are on the rise in Japan, with fraudsters employing techniques such as Quishing and physical QR code replacement to steal financial data. A recent incident involved a 60-year-old man who lost ¥106,000 (approximately $720) after scanning a fake QR code flyer. Experts have issued warnings about these scams, which have also been reported in locations like food courts and parking areas in central London. Victims have reported unauthorized charges after scanning counterfeit QR codes, prompting authorities to advise caution when using QR codes for transactions.
