Print Your HID Prox Card with Quality ID Card Printer
Technology has a major role on the improving security. It is often used with an identification card printed by an ID card printer, a proximity card works within a complex access control system to authorize access.
To have a system like this, an organization must have a card reader, an access control panel and a computer to power the system. When installed correctly, the complete system functions in place of a human security office. Credentials are reviewed electronically and only authorized card holders are allowed in buildings or on computer networks at authorized times in the day.
The code inside the card is binary code. This is a series of ones and zeros that have a specific sequence. The binary code is transmitted to the card reader. The purpose of the reader is to obtain the coding and transmit it to the access control panel where the code is analyzed against the database. There may be times that additional coding is found inside the card besides the actual coding needed by the access control panel. The reader is able to distinguish the correct coding and will only transfer the sequence code to the access control panel for review.
When receiving the code from the reader, the controller processed the code. The first step completed is to analyze the length of the data string and the format of the coding. Once this step is completed and the coding fits in with the specifications set for access, the controller moves forward to the next step.
Continuing the review of the card data, the controller reviews the card number. Numbers may be unauthorized or authorized for specific times and dates. If all matches, the lock relay is activated by the system and the door is opened for access.
If there is anything in the sequence that does not match, the controller will deny the access requires. Some systems are unresponsive. Other systems will provide a response to the card holder indicating that the access is denied and some may even provide a reason code.
It is standard for those who maintain the access system to modify the database through the computer on a frequent basis. The software application can be accessed from the computer by authorization. When authorized, an operator can update card holder information, disable or enable cards permanently or for specific times, and they can configure the door access hardware as needed.
Reports can be provided through the software application for review of access requests, approvals, access denials and other various reports about the system use.
