Jacob wants to know if paying electronically is secure. He doesn't like that it has a digital paper trail that people can see what he's spending his money on. Leo says that there's a fine line between the security of digital transactions and the privacy concerns that come with them. Leo also says that facial recognition and the prevalence of security cameras are a larger concern. The police can follow you everywhere using facial recognition and know where you are at all times. So he's more concerned with that.
