i have tried it once, i have used a black marker to cover the 3 numbers permanently, but some how it was not perfect i were able to read them again.
my advice is no need for any card, just use the cash, and for withdrawal ( I am using mobile cash option, where you can withdraw money from the Bank’s ATM without card only by an authorization number sent to your mobile ) check this option in your country here it is available since 3 years back.
