I am planning to travel and thought about credit-card theft.
Would it be a good idea to have a piece of paper with 2 fake PINs near my credit-card?
The imagined attack goes as follows:
The piece of paper has written only this on it:
Credit-Card PIN: 3867 7349
- Attacker steals wallet / credit-card along with the piece of paper
- Attacker goes to ATM, puts in credit-card and tries first PIN -> gets rejected
- Attacker thinks, he might have mis-typed the PIN, tries again -> gets rejected second time
- Attacker uses the second PIN -> gets rejected the third time -> ATM keeps the card
In my mind this is some sort of social engineering attack on the attacker. Since he has a piece of paper, he is inclined to use it in order to get fast cash, which results in the credit-card being kept by the ATM.
If the piece of paper would not be there, he might take it home and use technical devices or uses the credit-card in fake transactions to get money.
Notice: I am aware of criminals using fake / tampered terminals in order to get the card information and the pin. My question is about the physical theft of a credit-card!
I am also not sure, if there are different credit-cards, therefore I am thinking of my german banking-card, which uses Maestro. It's not a credit-card per se, but for the general idea of getting money at an ATM with a card and a PIN its the same as a credit-card if I understand both systems correctly.
PS: If your PIN matches my randomly generated PIN from the example, please offer me your credentials, so I can abuse this statistical surprise accordingly!
