Increasingly, credit card transactions are verified using so-called security codes. Yet despite – or even because of – this apparently positive development from a technical point of view, caution is still called for when using your credit cards.
As revealed by an SRF report last week, illegitimate credit card transactions, if verified by a security code, are usually not reimbursed by financial institutions.
You should therefore ensure that criminals are prevented from bypassing two-factor authentification or are unable to get their hands on your credit card details in the first place.
- Stay alert and don’t fall for faked websites or phishing attempts, since these can also be used to capture credit card details and security codes.
- Keep your devices up-to-date, so that criminals cannot hack and read out any security codes.
- Some financial institutions offer the option of using so-called virtual disposable credit cards. These can remedy the situation, since they are only valid for a single transaction each time and cannot therefore be abused afterwards.
