I scanned a QR code for a Lumos Learning book to access their online content associated with my purchase. I didn't realize it was "Fraavy" and assumed Lumos wanted to verify my payment information to make sure I was the one who purchased the book. I didn't see the content, so I typed the web address from the Lumos book which took me to the correct website.
I was suspicious of course and Googled "Fraavy" and came across others with similar scenarios. There was a $1 draft on my bank account. I called my bank immediately and canceled my card.
I will absolutely be more vigilant when scanning QR codes from now on. I never realized this could be an issue!
