<They do screen or even block RF, but is is mostly on the casino floors. Cell phones are sporadic on the floor, and if your phone does manage to work while you are playing and have to take a call, they make you step away from the table. >
Dan, it's funny how modern technology is always scary and people don't know how to handle it. Authorities are always ponderous and stupid. For example, banning holding cellphones, as though having an arm held up in the air affects driving ability in an automatic car.
They are now starting to understand that it's the brain which has to be focused on the job, not the hand hanging limply on a steering wheel, or resting on the arm-rest.
Hands free phones are not significantly safer to use than hand held. It's funny that authorities [and the public] have trouble figuring that out.
They are losing ground anyway. Voice activated, or auto-answered phones, with hearing-aid style earpieces mean calls can be answered without doing anything other than speaking. The authorities will have to make it illegal to talk in a car. Which means being able to speak without moving lips will be a talent people have to acquire. Ventriloquists will have no problem.
Similarly on the casino floors. It won't be evident that people are using cellphones. They'll just be sitting there, chatting away, maybe even with a retina scan giving them visual data too, yet looking as innocent as can be.
With nerve transducers, there wouldn't even be any voice to suggest that the person is talking to somebody outside the gambling zone.
Those sneaky phragmented photon CDMA2000 secret cyberphone signals will have to be screened.
Meanwhile, the dopey laws trying to stop people using cellphones while driving cars continue to be enacted. It's all part of the government programmes to suppress individuals having their own brains and using them and being responsible for what they do.
