My friend says there are calculators that can communicate with each other, is this a thing. 

 

We would like to capitalize.

Texas Instruments has some pretty expensive graphing calculators that can communicate with each other but they are banned in most learning institutions as well on government exams.

ummm, get back on-topic.

the prior comments had nothing to do with calculators.. just jibber-jabber.

Yeah. All Texas Instruments graphing calculators support serial communication so you can program them from a computer. Depending on the age of the product you may or may not have to write the program to get them to communicate. But this is useless for cheating, they have to be connected by a cable. 

Think about it, calculator manufacturers aren't stupid. They probably will never put things like bluetooth on a calculator because it's not really useful in the workplace and they realize it will only be used for cheating, and they have a reputation to uphold. The HP Prime has a wireless kit so you can use Wifi to download new apps from their app store, but it's actually just a wifi dongle that you have to connect to the serial port on the calculator, so not much use for cheating. 

If you were really smart you could build your own mini rf cards and put them in the calculators and use them for short distance communication, almost like long range SFC, but that's a different conversation.
