There are many different keypads to choose from, each with its advantages. When you look for a keypad for your place of business, think about which features can benefit your business. Below is a list of some attractive features available in the keypad world.

• Programmable
• Remote management
• Interact with electric or magnetic locks, the security system, elevator controls, and gate controls.
• Multiple or unlimited access levels (authority codes) such as – master, managers, supervisors, groups, individual users, service people, events and emergency codes
• Anywhere from 2 to thousands of user codes
• Programmable for hundreds of scheduled events
• Can control multiple doors per site and multiple sites
• Programmable entry time to re-lock allowance
• Individuals, groups, or all user codes can be temporarily disabled or permanently locked out.
• Programmable to lock out users after a certain number of failed code attempts
• Generate Management reports. Some will generate as many as 40,000 audit trail transactions and access events.
• A 4 6-digit combination will offer 10 thousand to a million combination possibilities.
• Weatherproof for outside use.
• Encrypted.
• Keyless or with keys.
• Fire-rated.

• The magnetic stripe reader uses a sensor that reads the magnetic oxide stripe laminated to the back of the card. The information is compared to stored in the reader or a remote system. Some readers include a crucial cylinder lock in case of power failure. This card is inexpensive to produce, holds more information than a bar code, and is easy to program. However, they tend to be worn and misread, and devices can steal the data for that purpose.
• The barcode reader reads barcodes, each made up of alternating dark and light, thin and wide stripes read by an optical scanner. Their organization is determined by the barcode protocol selected. This technology is inexpensive, and credentials are easy to generate and print on cards or other items. However, its simplicity also makes it very susceptible to fraud.
• The RFID proximity card reader radiates an electric field around itself that picks up the code on the card that comes into its proximity. Each card has a facility and user codes similar to your bank checks. The card cannot be erased and can be read even when in the user’s pocket or purse. However, since no centralized system controls the numbers, different companies can have the same codes. Consequently, manufacturers have created the formats that they hold and issue.
• The intelligent card reader has an embedded read/write microprocessor and memory chip and, like a computer, can do what it’s programmed to do. Thus, it can do more than access control. The smart card used for access control is contactless, using radio technology with a higher frequency than the proximity card. Consequently, it transfers more data, reads cards in the user’s pocket or purse, and can read several cards simultaneously. Criminals can tamper with the readers when they are manufactured or before they are delivered and harvest information from them after use.
• The Biometric reader identifies an individual’s fingerprints, hand, iris, voice, and face by comparing them to stored ID templates. Some readers can store 50,000 ID templates. Other readers refer the biometric ID to templates stored at a central server. If the person is found in the memory bank, their identity is assessed for access level. Based on the permissions for that level, the door hardware either unlocks or remains locked. These readers eliminate the need for cards (which can be stolen, lost, or borrowed) or for remembering PINs. However, to expedite the process, most biometric readers work with cards or pins to skip the ID search (most searches process 2,000 to 3,000 matches per second) and go directly to the comparison. Since most intelligent cards have plenty of memory, they can also store biometric ID templates.
