Paul Wilson for a comprehensive overview of the potential ways that credit cards and contactless payments can be compromised, and for connecting us with Christopher Forte. A big thank you to Christopher for his technical advice on different attack vectors for NFC transactions, his insights into the “cat and mouse game” between hackers and security providers, and feedback on different parts of the video. Thanks to Pavel Zhovner, CEO of Flipper Devices, for talking us through the various security layers in NFC transactions, showing us round the Flipper HQ, and even giving us several Flippers to experiment and film with!

This is because both its spin and charge should oppose the electron’s. This would mean both would bend in the same direction! We’re interested in seeing the difference in the spins so we flip the machine to make this clearer. **We show curved spacetime using Flamm’s Parabaloid, which we discovered is controversial, more notes on that here - https://ve42.co/HBDFlamm
