Is it secure to provide debit card information over the phone? So here is what to pay attention to when providing card details, especially on the phone: If using the Internet, make sure the good or service you want to buy comes from a reputable web site.

With that being said, always research the company offering the service or product beforehand. Never make your card details shown in public. Never provide your cvv number when asked on the phone or when processing a card payment in person. This is a sure sign of an impending fraud! CVV numbers are for online purchases only!

As it turns out, CVVs are not random three- or four-digit numbers. Rather, banks generate them using four pieces of information: primary account number, four-digit expiration date, a pair of DES Data Encryption Standard keys and a three-digit service code. For obvious reasons, the precise algorithms used are unknown. To avoid becoming a victim of credit card fraud, you should protect your CVV like any other important piece of financial information.

Here are seven simple ways to prevent your CVV from falling into the wrong hands. Banks and merchants stepped up security for in-person transactions with the introduction of chip-based debit and credit cards. This technology enables the internal code to change each time the card is read, a vast improvement on the magnetic strip.

Not surprisingly, this has been very effective at reducing fraudulent activity. But what about CNP card-not-present transactions, such as those taking place online or over the phone?

Clearly a physical chip will not be helpful; this is why there is a CVV printed on your card. However, the most skilled criminals are sometimes able to access CVVs, even though merchants are prohibited from digitally storing them.

This would happen on a miniature lithium battery-powered screen on the back of the card. Selecting the frequency of the code change has its difficulties, and the cards would likely be four to five times more expensive to produce than current models. That said, the fraud savings could more than make up for the increased production costs. Accordingly, other methods of generating dynamic CVVs have been developed, but none have seen widespread implementation yet.
