For the curious, it takes approximately 4 layers of aluminum foil to block a scanner from activating the RFID signal when your Al lined wallet is point blank from a standard scanner.
(After receiving an RFID enabled ID card here in the Netherlands last year, I tested it on our office copy/scanner RFID reader, and then simply lined my wallet with double the number of layers it took to block the signal. Works like a charm!)
With recent news about certain Android apps sending private information to whomever created it, I have recently installed DroidWall to filter access (e.g. - Battery meter apps!? Puh-leez!) to my phone's data connection.
If some app expects me to allow a data connection just to prove I am not a thief, sorry, I won't be buying it! And yes, I do purchase apps that I consider worthy.
And what happens if someone is abroad? Would they have to pay $20 in roaming charges to play some bubble bobble game for an hour while waiting in some airport?
Where do you suggest they go to get "proper training" for a motorized office chair?
Since they were using it on the streets, they could start by getting a driving license like everyone else that operates a motorized method of transport in public.
Now I am not sure about this, but I think in Germany you can't get a drivers license until you are 18 (and they were 17). Ironically, it probably would be safer for these guys to be driving a car on the streets than that contraption they built.
I am all for inventing things like that and having fun with it - but on private property where they can only hurt themselves and their own property not other people if something happens to go wrong.
Imagine that police arrest an individual for a simple traffic infraction, such as running a stop sign. Under the search incident to arrest doctrine, officers are entitled to search the body of the person they are arresting to ensure that he does not have any weapons or will not destroy any evidence. The search incident to an arrest is automatic and allows officers to open containers on the person, even if there is no probable cause to believe there is anything illegal inside of those containers. What happens, however, when the arrestee is carrying an iPhone in his pocket? May the police search the iPhone's call history, cell phone contacts, emails, pictures, movies, calendar entries and, perhaps most significantly, the browsing history from recent internet use? Under longstanding Supreme Court precedent decided well before handheld technology was even contemplated, the answer appears to be yes.
If you had better tools, you could more effectively demonstrate your total incompetence.
