So how does a PINSentry work? I can see how a random number could be generated quite easily
But how does your tablet know its the right one when you manually enter the numbers to authorise the transaction, or how does the PS know you are entering the right numbers from the bank generated system, to respond?
Because I'm not aware that they are a Bluetooth device or a GSM.....
Witchcraft I tell ye.
Pretty sure it’s based on an algorithm. The generator is designed to churn out random numbers which match a specific pattern. For simplicity’s sake, all even numbers, containing either a 1, 3 or 5 as their second number, all numbers add up to 22. That type of thing.
If the number meets all of those “rules” and hadn’t been entered before, then it’s valid.
No different than having a password you give to someone….but instead of it being “Apple”, saying any British grown fruit would do. Or instead of being “pendimethalin” any one of the million actives available which are safe for use only on wheat would suffice. If someone tried to copy it and said “glyphosate” you’d know they were lying.
