That is correct, it is not recommended to carry your Personal Identification Number (PIN) in your wallet as it could fall into the wrong hands. If someone gains access to your wallet, they could potentially use your debit or credit cards if they also have your PIN. To prevent this, it is best to memorize your PIN or keep it in a secure location that is not connected to your physical wallet.
It is also a good idea to choose a unique and complex PIN that would be difficult for others to guess, and to avoid using easily accessible information such as your birthday, address, or phone number. Additionally, be cautious when entering your PIN in public places and shield the keypad with your hand to prevent others from seeing it
