Scammers attempt to take advantage of people and defraud them in many shapes and forms. There has been an uptick in gift card fraud across the country in recent months. A common scenario may look like this:
A scammer contacts Barbara stating that she has a warrant out for her arrest in another state. They demand payment for the warrant in gift cards immediately or else they are going to have her arrested. Scared and anxious, she goes and purchases gift cards using her debit card at various stores (Google and Apple Gift cards are the most common ones). She then sends a picture of the card to the scammer with the card numbers showing, which are then drained, and all the money is gone.
