Khadim's — for card (credit/debit) payment, taking card number details in their system

Address:

Khadim, Thakurpukur Bazar, Kolkata, West Bengal, 700063

Hi,

My name is Debalina Dey. I have purchased 2 pair of shoes from Khadim (Thakurpukur, Kolkata) on 24th of December 2019. At the time of paying the bill by credit card, before swiping the card the shop guy took my card and entered my credit card number into the system. Upon asking the reason for doing so, he informed that this is the new rule of the store and everywhere they are taking these card details before paying the bills is mandatory. Then I told the guy that I purchased shoes from the same store 1 week back and made the payment via credit card and the different cashier guy did not take my card details, then why now? He only kept on saying that "this is the new Khadim rule .
Since, he already have my card number, I am a worried he might have memorized my credit card's CVV & exp date and do online transactions. This is a risky affair.
My name is registered in the stores's database on that particular date.

Please look into the matter as this might lead to credit card fraud.

Regards,
Debalina Dey
