Problems solved by technology

However, this method is not flexible enough. In the use of physical stores, there will be a phenomenon of concentrated and frequent card swiping. If this method is adopted, after each transaction is completed, it is necessary to wait for another 30 seconds before the next transaction, which seriously affects the collection. Therefore, a method of protecting the PIN input of the POS machine that can protect the PIN input and avoid affecting the user experience is needed

Abstract

The invention provides a PIN input protection method, device, storage medium and POS machine. By setting two parameters for detecting the total number of times of PIN input and the sum of the time spent, it can be switched to the PIN input display state for the user to enter the PIN. As a barrier to prevent PIN exhaustion; it also uses the combination of the total number of PIN input times and the sum of the time spent to determine whether the PIN code has been artificially exhausted into the PIN code, avoiding rigid setting intervals to limit exhaustion, but In a flexible manner, the number of PIN input within a certain period of time cannot exceed a predetermined number, which can not only protect the PIN input but also avoid affecting the user experience.

Description

Technical field [0001] The present invention relates to a cryptographically secure POS machine, and in particular relates to a method for protection of the POS PIN input means, the storage medium and the POS. Background technique [0002] Based on consideration of safety design, POS terminal when PIN entry is required to prevent people to break out of the cardholder's password using the exhaustive method. The conventional approach is to enter the PIN each time interval is not less than 30 seconds. This is 60 minutes no more than 120 times. However, this method is not flexible enough, there will be focus on the phenomenon of frequent in-store credit card use, but if you take this approach, each transaction is completed, it is necessary to wait 30 seconds for the next deal, seriously affected the collection efficiency, and therefore a need for a PIN to protect and to avoid input protection methods affect the experience of the POS PIN input. Inventive content [0003] The present i...
