Haha, there was such a project, but unfortunately failed. I hope the leadership of Bonafi will take into account their mistakes and will follow the right path!
Their crypto-tag technology is much more secure and Bonafi's crypto tag can not be faked. This is the main difference. Do not worry about it.
Correct. Bonafi's authentication system is differentiated with other competitors with the Crypt-Tag. It is a cryptography built-in NFC tag. Duplication of the Crypto-Tag is simply not possible. This is the key feature that makes it unique and authenticated through the blockchain in a decentralized public ledger way.
