Смысл: The text suggests a physical workaround to prevent the theft of the CVV2 code by erasing it from the card and using a mathematical key to remember it, while reminding users to also use digital security tools.
The author suggests erasing the CVV2 code from physical payment cards and using a mental formula to recover it to prevent theft during physical loss.
Смысл: The author proposes a method for managing numerous credit card PINs by writing 'encrypted' versions of the codes directly on the cards using simple mathematical shifts and permutations to prevent theft from leading to immediate fund loss.
The author suggests writing 'encrypted' PIN codes on bank cards using simple substitution and permutation algorithms to balance memorization needs with security.
Смысл: The main idea is that masking the CVC code on a payment card with a sticker can prevent fraudulent online charges resulting from physical theft of card data in public places like restaurants.
Cover your card's CVC code with a sticker to prevent dishonest staff from stealing your details for online fraud.
