I always felt that gift cards are the underbelly of the economy. I don’t think that’s an accident, these things are great ways to move money and pay casual labor without the red flags that cash throws up these days.
This book [1] from 2011 by Kevin Poulsen about the carder Max Butler (alias Iceman). Runners would use his copied CCs (which he acquired via cracking into conputers) to buy gift cards in physical stores. Nowadays we got CVV (CVC).
What red flags does cash throw up that are circumvented by gift cards?
One time I got a car detailed, and when I was paying at the end, I noticed that the employee was writing out a receipt and marking that I had paid with a gift card. I don’t remember if I was paying with cash or a credit card, but either way I figure some sort of tax evasion and/or money laundering scheme was happening.
