The most common way now is with a radio tag. It is a tag, sometimes hidden in the package, that sends out a weak signal. If the tag is not turned off at the checkout, it will be picked up by the reader at the front door, and the alarm will go off. When you purchase the item, the salesperson will drag it over a piece of equipment that neutralizes the tag. Sometimes you can hear a noise as it is done and sometimes it is silent.
A common misconception about anti-theft devices is that they are able to detect barcodes on stolen items. This is untrue. Unless the item has a magnetic or radio tag on it, the item will not be detected by the device.

What is the difference between an integer and a Boolean variable?
An integer stores a whole number. The exact range depends on the language; in Java, "int" stores whole numbers in a range of approximately minus 2 billion to plus to billion. A boolean variable, on the other hand, stores only one of two values - these are often called "true" and "false" (as in Java). Boolean variables are often used to keep track of information that can be thought of as a reply to a "yes/no" question. For example, to mark whether a certain item is active or not you have only two choices, so it makes sense to use a boolean variable.

Can please tell you 10 difference between tools and equipment?
Equipment are especially MADE for purpose. Equipment can include helmets, kneepads and so forth, and is a more general term... Tools are objects to work WITH. Tools is American word. Equipment is a set of tools. Tools in a non-literal sense are devices to use to do something, for example, "LANGUAGE IS A TOOL TO PROMOTE SPEAKING..." lol Equipment is basically to "equip" somebody. You cannot equip someone with a spanner or a screwdriver. Tools are commonly used for machinery. Tools are generally small, hand held, common items. Equipment are profressional items.
