Credit Card Compromised

One of our credit cards was compromised!  A number of transactions had gone through.  But a large one notify us.  So we called the card center.  There were a number of transaction that went through at $1.40 which is US$1 before the big transaction.  So the syndicate must have tested the card to make sure it is live and transactions can go through before making big purchases.  The purchases were all done on the internet.  One puzzling thing is the transactions went through without an sms to put in security code.  So far, every time when we buy stuff via internet there is a requirement to enter a code send through SMS.  So the security system of the credit card may be compromised as well.

So please watch out when you get unusual transaction on your credit cards.
