Yes. you can have that type of device, but, because the technology has advanced, there are now devices that are much smaller. Some are also portable. I even know someone who bought one for himself and keeps it in his car or in his house. Given the current competition in manufacturing the products, a device of that kind costs about $1,000. The device is not very big and it can be easily carried around by anyone who wants to buy one. It measures about 1 foot by 1 foot. It looks like the devices that usually hang on walls.
