re-bank pin generator

joe134

Hi, Just received our new security number generators from HSBC.Have to make sure they are not mixed, so I,ve marked them.Can anyone tell me how they work? Is each one allotted a number of 6 digit numbers unique to that generator?if so, what happens if one,or two, are missed,as they disappear pretty quick? Just curious enough to ask Guys, no doubt you won,t fail me:beer:

It does not matter if you miss some codes.

Did you have to register it when you first got it?
It changes using a mathematical function using prime numbers around a fixed secret ID (it's complicated....)

The bank knows the ID of your fob and the code when you regestered it and can work out what number it should display at any given time (the time between code changes is constant)

Thanks SOlitaire. Very informitive.Reading the link, it,s not infalible, but, probably more secure than just a pin. Loss being the main one.Thanks very much, much appreciated.Can switch off now::j
