[Re: Mike Cottrell’s post 4-3-20: “As far as Exchange protocols have always been to have a DeLarue machine verify each currency. I assume it would still be a sanitary way to do it with minimal contact”] None of this is accurate. The De La Rue machine is not an automated authentication protocol. Anyone saying it is – or speaking as an “authority” on the subject is making it up as they go. It is a high end counter and “screening device” – IT DOES NOT AUTHENTICATE ANYTHING. I have spoken to the engineers who designed it (in London) on a number of occasions. This was their description directly to me. Had it been the device everyone is claiming – I would have bought (or leased) one. It is not.
