Security is a fact of life for some individuals. Some institutions take a welcoming, low-security approach. Churches and other religious institutions usually use this method. When someone deals with a larger institution, they want to make sure that only the people they trust have access to this. Mints may worry the most about security. They even do the best they can to prevent people from counterfeiting official funds. These buildings, as well as buildings such as Fort Knox, have rather complex entry systems. Most buildings need much less sophisticated entry systems. The less need there is to keep someone out, the less complex the product will be.

The Oldest Entry System

Doors are one of the oldest entry systems to a building. Even huts had a way for the occupants to get in and out. The early huts and stone dwellings did not allow the user to close the door. Without the ability to close the door, there was no lock. Of course, this was the least secure entry system, but it is still in use today. The next advance in security came about when society invented the door.

Upgrading to the Door

The earliest doors were created to give people extra privacy. They prevented people from looking into a hut or other dwelling. They were designed to keep the people inside from revealing their activities to the outside. Eventually someone realized that they wanted to look out. Windows came about not long after. However, the earliest doors were rudimentary. People could still come and go as they pleased. The invention of the lock took the idea of entry systems out of the stone ages. Now, the occupants of a house could keep people on the outside and protect the contents of the inside of their homes. Locks have come a long way since their first introduction.

New Technologies and Modern Systems

Although the tumbler systems increased in complexity, the basic technology remained the same. The basics of entry remained either key or combination. It would take an incredible technological leap forward for this to change. The idea of electronic entry systems became a possibility in the second half of the Twentieth century. The magnetic card reader has allowed people to access hotel rooms. It has also made things more convenient for customers. Companies have also used the entry to guard some of their more sensitive areas. Retina scanning entry systems are still entirely fictional.

Entry systems are not a direct part of preventing counterfeiting, although they can keep the areas where the plates are stored far more secure. Most people who are interested in protecting forms of currency use a different strategy entirely. They make the process of creating an effective copy extremely difficult. The most recent incarnations of pound notes show this. The United States dollar denominations have become incredibly complex in recent years. They've also started to take on the look of the currency used by the Monopoly board game. The latter is probably unintentional, but it is amusing.
