RFID stands for Radio Frequency Identification. The name suggests itself, the technique use radio waves to identify something. It signifies to small electronics includes a small chip and an antenna. This device is used as an alternative to a barcode or magnetic tape; they are used for giving identification to each item.
RFID consist of these components:
It can be a computer with a microcontroller and its receiver the reader input.
It is a microchip attached to a small antenna and encapsulated with different material. It carries information in different forms.
It is one type of scanner, it scans the information, or signals coming with the tag.
Depend on RFID type; this could be one way or bidirectional. Only the tag( usually contains a number) can send information in one way and in bidirectional the conversation is from both sides.
Every access control system is working with the RFID card like we said employee card. There is a tag attached with the smart card and it is mounted to secured doors. All system access people are linked to a number that is already on the tag. This number is matched with the database which is actually stored in the official data. If reader catches right radio signals and access rights, then it is okay for person and signal is sent to a system for opening a door.
There are many varieties of this card like it is also used in vehicle access control system, used in taxis and ambulance. It is made customizable for every possible system like for health department, logistic, library, taxi stands, stores, etc.
There are two types of RFID systems:
This RFID system has own power source, like battery or external supply. This is used for long distance like logistic. You can track your logistics with the help of this.
This is used for short distance, and it gets the power though reader or tag antenna. There is no need to having an own power supply.
Uses and application
The most common application is for tracking. It includes:
We provide a RFID card for all the access control system likes for employee badges, student cards, and vehicle system. You can get number of advantages to in contrast to the barcode. Stay tuned with us for more enquiry.
