Abstract
The present invention provides a method and an apparatus for detecting anti-skimming magnetic interference, wherein the method comprises the steps of: S1: generating an original magnetic strip signal; acquiring an interfered magnetic strip signal by combining the original magnetic strip signal and an interference signal of an electromagnetic interference source to be tested; S2: decoding the interfered magnetic strip signal to obtain a decoded parameter; and S3: determining whether an original magnetic strip parameter is consistent with the decoded parameter; if so, obtaining a first test result that the electromagnetic interference source is unqualified to satisfy a magnetic card reading device's requirement for electromagnetic interference; otherwise, obtaining a second test result that the electromagnetic interference source is qualified to satisfy the magnetic card reading device's requirement for electromagnetic interference whereby security of the magnetic card reading device can be enhanced and the magnetic card can be protected from being skimmed.
