I'm considering to black out CVC2 (card security code) from all the bank cards I have. The reasons are:
- in the country I live, debit cards are often taken away at restaurants, so they easily remain out of my sight for 5-10 minutes--so any waiter can easily steal CVC2 plus card number (and sell it to someone, or abuse himself)
- I keep all the bank card details in password manager software, which is always with me
- my bank officially allowed me to black out the codes if I wish to
So I wonder if there are any reasons I miss why blacking out the codes could give any problems for me in future?
