The cards work with the chip even if there is a magnetic stripe. The latter is used only when the terminal does not support chip technology, and its presence does not compromise the security of transactions made with the chip.
If the ATM does not provide the cash, the user must contact their bank to report the problem. The bank will initiate an investigation and refund the amount if the disruption is confirmed.
Cash trapping is a technique in which ATMs are tampered with to hold money instead of disbursing it, and the cash is then recovered by criminals. Users should immediately report any unsuccessful transaction to their bank.
Skimming is a fraudulent technique in which a device (skimmer) is installed on ATM or POS terminals to read and copy magnetic stripe data. Criminals can also use hidden cameras or fake keyboards to capture the PIN. However, these scammers cannot replicate the chip, so transactions made with chip technology are secure.
