iSignthis Patented KYC method, page-18

As others have pointed out, this method has been around for years.

The ISX method, according to their material, is to split the actual transaction into two components which form the 'secret' that the account holder must verify - rather than doing a small test transaction. A minor point of difference, but it is a difference and it's what they have patented.

"Game changer"? I'll put that down to marketing speak. But OP is definitely being disingenuous here.
