Title: POS MACHINE, AND METHOD AND APPARATUSES FOR PROTECTING SENSITIVE DATA IN POS MACHINE
Abstract:
Disclosed are a POS machine, and a method and apparatuses for protecting sensitive data in the POS machine. The method for protecting sensitive data in the POS machine comprises: detecting whether a pin level of a connection protecting switch changes; when it is detected that the pin level changes, determining whether the pin level is restored to an original state within a preset time; if not, deleting the sensitive data stored in the POS machine, and if yes, re-detecting whether the pin level changes. The present invention also provides two apparatuses for protecting the sensitive data in the POS machine. By using the two apparatuses, interference of an interference signal to the POS machine can be effectively filtered, and the interference resistance and stability of the POS machine are improved.
