PIN pads are an essential component of sales equipment, not just for large retailers but also small businesses and service providers as well. Debit cards, gift cards, benefit cards and even credit cards may need a PIN number entered along with the purchase, and for that you need a PIN pad.  This is why Bank Keshavarzi has equipped its branches and applicants with latest models of pin-pads, compatible with different machines and systems. So far (February 20, 2012), the bank has managed to operate 3,430 pin-pads.
