Tag Hijacking Shield

Read full description

When you read a QRCode or NFC tag on a street by your device, do you ever wonder if it has been hijacked? If the last page you opened was the one you wanted, would you have accessed the hijacker's server by the time you got there? This is a tool to whitelist to make sure it hasn't been hijacked ( the QRCode for a specific service should be read in an app dedicated to that service.). As this whitelist is just starting to be created, you are more than welcome to participate in the expansion of this whitelist by notifying our service of any unlisted QRCode or NFC tags. So sorry, though, there are no levels, titles, or awards. With your explicit permission, we would appreciate it if you could also provide us with information about the appearance and location of the tag and allow sharing them.
