What's inside your bank card

@DeeRuddock @stux same here! I thought it was really interesting.
The interview with the OG card cloner brought up so many cherished memories... of... uh... doing absolutely legal stuff like that, back in my dumber days of yore. 
@stux usually even a better light source (like the one from phone's camera) is enough to see through the card ;)
Also, yay, Hannah Fry! :}
@stux lovely sequence, very informative.
Putting an industrial solvent into a drinking glass that will later be re-used for drinking, even after a wash, is a huge no-no though. ⚗️☠️
Wow!
