Özet: Since financial and personal data pass through point of sales (EFT-POS) terminals, it is crucial that information can not be intercepted by external intervention. Therefore, various measures are taken with software and hardware solutions. With the precautions to be taken, the conditions in the payment card industry (PCI) directives are met. As technology develops, new attack methods are emerging. The directives are updated periodically to protect against new attacks. The most important of these is that the device detects tamper attacks. In this study, the implemention of a tamper-proof safe zone for EFT-POS device is described. Unique solution is implemented to ensure safety. For the security of the EFT-POS terminal where the Maxim processor is used, the focus is on smart card and keypad protection sections.
