Working on a new app to let manufacturers (or anyone who makes things) print unique QR codes that let you verify that a product was indeed made by them with modern, secure cryptography. Think helping people know that their Gucci handbag is authentic with surety. Scan the codes below - one is bad and one is good. Mostly thinking about letting consumers verify prescription drugs in the developing world and by mail order. Hope to make it free. For the technically inclined, you can pull the code and generate your own public and private keys and QR codes to work with the app at: https://github.com/verxcodes
Work in progress... Verified for iOS Safari and Chrome on a PC so far. Let me know how you fair if you try it out! Good and bad codes for scanning can be found on the Github team site: https://github.com/orgs/verxcodes/teams/all-members
Quite a serious problem. Help and suggestions are most welcome! All OSS!
