Too techy for voters?

The Oystercard - one of the transport innovations that Ken is using to bash BoJo around with - has been hacked. Well, kinda sorta. A bunch of boffins in a lab have figured out a way it could be hacked, and these days that's normally enough.

So will BoJo make hay with this? And will he be able to explain "RFID technology" and "logic gates" in ways which don't make him sound like a buffoon? Watch this space. And keep an eye on your Oystercard.
