Are you ready for QI codes?

Electra turned to Orion. "We need a way to commandeer a bunch of mobile devices to carry out our DDOS attack."

Orion shrugged. "There's no way that we can commandeer a bunch of mobile devices."

"Oh, but we can!" Electra replied. "All we have to do is target teens and early adopters. They're gullible enough to do anything we want."

"So how do we do it?"

"Easy." Electra grinned in satisfaction. "We'll set up some incomprehensible graphics and tell the teens and early adopters to point their mobile phones at them. They'll be gullible enough to do so, and then we program their phones to do what we want!"

"Oh, I get it!" exclaimed Orion. "We get them to point their iPhones at the images."

"iPhones?" snorted Electra. "My MOTHER uses an iPhone! No, we'll do it with Android devices."

"So how do you con them into capturing the images?" asked Orion.

"Easy," replied Electra. "We'll put a picture of Ashton Kutcher on an advertisement, and then tell the users to scan the QI code."

"What does 'QI' stand for?"

"Quick infection."
