IC3's announcement piggybacked off an earlier warning from the FBI.
“Although EMV cards provide greater security than traditional magnetic strip cards, an EMV chip does not stop lost and stolen cards from being used in stores, or for online or telephone purchases when the chip is not physically provided to the merchant, referred to as a card-not-present transaction,” IC3 wrote.
Possible theft can also occur because some cards aren't equipped with a PIN. Some retailers also haven't yet implemented EMV chip point-of-sale terminals.
With that in mind, IC3 recommended users “closely safeguard” their EMV cards and PINs.
Merchants should also take “additional security precautions” when conducting sales online or over the phone, IC3 said.
