I have recently had my new bank card and enclosed the leaflet that explains about the mass conversion to PIN authorisation from signatures
Is this a opportunity to buy the manufacturers and suppliers of the PIN input key pads
If so can any one advise the companies who should benifit from this massive project

Look at ID Data (IDD) (especially this BB)
They don't produce the key pads you mention but they are expected to play a large part in the production of the new chip and pin credit cards we are all soon to have
This one could really fly

Got to use one of these pads yesterday for the first time.
Didn't think to look at the name of the manufacturer.
I am going back there again tomorrow probably.
Will chek then.

Thank you for your assistance, have had a look at IDD and had a chat with the MD and have made a purchase. They have a contract with the Post Office as above, software not hard ware.
