What to do if you find someone else’s bank card | Kaspersky official blog

The content explains the security risks associated with finding a lost bank card, emphasizing that sharing card details publicly or entrusting the card to strangers can facilitate fraudulent use and legal complications. It advises contacting the issuing bank to report the found card, allowing the bank to block it and notify the owner. Subsequently, the finder should destroy the card to prevent misuse and avoid holding someone else's property. The article also notes that multi-purpose cards with non-financial functions should be returned to the relevant institution rather than destroyed. This guidance is intended to minimize risks for both the finder and the card owner.

If a lost bank card is shared publicly or handled improperly, criminals may obtain card details and use them for unauthorized transactions, potentially causing financial loss to the card owner. Additionally, individuals who hold or transfer the card to unauthorized persons risk being suspected of involvement in fraudulent activity. Proper handling by reporting to the bank and destroying the card prevents misuse and protects all parties involved.

The recommended mitigation is to immediately contact the issuing bank using the phone number on the card or the bank's official website to report the found card. After reporting, the finder should destroy the card by cutting it into small pieces to prevent any possibility of misuse. Avoid posting card details publicly, holding onto the card, or handing it to strangers such as store employees or security personnel. For multi-purpose cards with non-financial functions, return them to the issuing institution instead of destroying them.
