What is Electronic Access Control?

Electronic access control (EAC) is a high-tech form of security that involves using electronic power rather than electric power. Although electronics deals with electrical components and circuits like integrated circuits and diodes, it is the nonlinear activity of the circuitry that enables an EAC to control the flow of electrons that amplifies transmission and reception of signals. This allows security systems such as electronic door locks, access card readers and biometrics.

What are Card Readers?

Business, homes, apartment buildings and other New York City establishments protected with card reading EAC security systems require individuals to swipe or insert a card through or under the reader in order to gain access to the building or particular area in a building. Each card is coded with a set of unique data such as name of the individual, identification number and where that person is permitted to enter.

The technology employed to make a card and reader interact successfully is complicated and involves implementing magnetic particles to write information on the card using flux reversal. A person wishing access to a locked entrance protected with this type of security system only needs to present the card to the reader in a way that the reader recognizes the information coded on the card's magnetic stripe.

Biometric access systems

Biometrics is a category of identification validation using a reader that is quickly becoming popular with companies protecting highly classified information. Biometric electronic access control systems "read" a person's unique fingerprints or retinal pattern, two forms of identification that cannot be compromised since everyone's retinal pattern and fingerprints are unique and inimitable.

PIN Numbers and Keypads

More affordable than biometric and card readers are keypads requiring input of personal identification numbers, or PINs. Debit and credit cards use this popular security method by allowing people to perform a variety of bank transactions through an ATM machine equipped with a keypad. A major problem with security keypads involves computer-savvy criminals who are familiar with the type of PINs people commonly choose hacking into the accounts of unsuspecting people by guessing their PIN.

Homes that are secured by this type of electronic access system can also fall victim to professional hackers. For this reason, personal identification numbers should never be based on family members' ages, birthdays or names. Instead, PINs need to be an arbitrary and meaningless blend of numbers, letters and unique characters.

Although no security system is infallible, electronic security systems provide excellent security due to demanding that individuals wanting to gain access to a particular area provide an exclusive card, number/letter code or specific retina and/or fingerprint before being allowed to enter that area.
