I received a text message on on my cell phone (T-Mobile) service from "JPMorganChase DebitCard Issue" at the number "3520" asking me to call 714.661.5543 extension 105 to reactivate my bank card. (Hmmm... how did "they" know I had a problem with my card over the weekend?) The text displayed the correct name of my bank, but I smelled a rat. I dialed in, and was prompted to enter my CC#. I did so, but changed a few numbers along the way. I also made up an expiration date and punched in random digits when asked for my "4-digit pin number." I was then assured my card had been vaidated and reactivated! Yay! So, I wonder what kind of scam THAT was??? My advice: do not return the call or give any information.
I guess that if you provide your card number and your pin they can make a new card and use it. Someone I know here in New York got his card replicated and there were purchases made in Brazil. He found out because the bank called to ask him if he was or had been in Brazil recently. He never traveled to Brazil. He had the card in his possession all these time so it was a replica. As you can imagine he had to change his card. Read about ATM's on the streets. There are people who connect other stuff to them to copy your card info. Try to always use your bank's ATM. There is also a 818.864.3253# claiming to be from Chase.
