Nothing to declare?

Question

What do they really mean by that when in an airport

Answer 1

means that you have nothing that you should pay duty for

Answer 2

There are some items that you need to pay customs fees for getting them into a country. It depends on the customs regulations of different countries. This is particularly true for nationals of the country itself who may buy things from other markets instead of local markets. Some countries are tough in imposing the customs regulations, and some are not.
Sometimes you need to declare something to prove that you are getting it in the country. Some things need to be declared because special permission is needed to get them in. Violators of customs regulations are usually asked to pay some penalty in addition to customs due. In serious offenses, this may involves some jail term.
Going into the "Nothing to Declare" zone in any airport means that you don't have anything to declare for Customs officials. In airports where the procedure seems to be very easy and many people passing through this zone, it means that special equipment, like x-ray machines, are used in the backdoors to check baggage before delivering them to the passenger. If any thing is suspected, the baggage is monitored to see if the passenger goes into the "Nothing to Declare" zone or not. Any suspected violator would then be asked to be manually searched once he/she passes through this zone.
