RFID PROJECTS
RFID system means Radio Frequency Identification System. This technology uses radio frequency signals to identify objects with the help of radio electromagnetic signals transferred from RFID tags to RFID card readers. RFID tags are passive that do not need any external battery power supply. There are also some RFID tags in the market which consists on power source. Whenever any student come across RFID based project, he/she will find those projects very interesting and simple. On the internet, there is lot of RFID project ideas available.
WORKING OF RFID SYSTEM
Radio Frequency Identification system is mostly used for data capturing and automatic identification purpose. This system helps to automatically identify particular person or object. Once that person / object is identified, this system captures the data about that person or objects and verify with the existing data present inside the system. RFID system uses radio waves for accomplishing whole communication inside the system. At an initial level, this RFID Identification system is having 3 sections: RFID Antenna, RFID Card Tag or Label and RFID Card Reader. Here in RFID Card Label/ Tag, an integrated circuit and RFID transmitter antenna are present. RFID transmitter antenna transmits data from RFID Card label/Tag to RFID Reader which is also known as “Interrogator”. Later, RFID Card Reader converts received data into a usable formatted data. Whatever information gathered from RFID Card Labels or tags, is send to host computer server via proper communication interface. At the last, the data information will be analyzed and stored inside the host server database for identification purpose.
RFID CARD LABELS AND SMART TAGS
With reference to above discussion, RFID Card label or tag consisting of transmitter antenna and an integrated circuits. RFID tags are composed of some protective shield material that has capability of fighting against uncertain environmental conductions and can able to hold some pieces together. As per different applications, protective shield material is also changed. Now a days, RFID smart card labels or tags are come in variety of shapes and sizes. Out of them, some are active in nature and some are passive. In general, passive RFID cards are mostly used in RFID systems due to their compact sizes and cheaper rates. In case of passive RFID cards, RFID Tags or Labels are being powered by RFID readers before serial communication between RFID tags and RFID card readers. While in case of active RFID cards, there will be on board power supplies are present due to which they become costly and heavier.
RFID APPLICATION AREAS
Now days, RFID system is almost used in every industry for inventory management purpose. Following are some sector in which RFID system is used.
- Asset management tracking system
- Person location tracking system
- Secured Restricted Area Controlling Sections
- RFID card Badging
- Inventory Goods management
- Supply chain management system
RFID APPLICATIONS
- Highly secured RFID based system
- RFID based class attendance monitoring system
- Automatic home door controlling via RFID system
- RFID based automatic toll tax system
- RFID based water park sport billing system
Here in this article, we have mentioned some innovative and interesting unique RFID Project ideas.
HIGHLY SECURED RFID BASED SYSTEM
In this highly secured RFID based Security System, we are using inductive coil coupling along with RFID reader. The data which is modulated inside RFID card has been taken out by Reader when customer swiped his card with RFID reader. Later on, the gathered information by RFID system will be send to microcontroller for further processing. In security system, the data captured from RFID card reader, includes particular employee personal details. If those details are matched with the existing database of microcontroller then only, that particular employee will be allowed to access security system.
RFID BASED CLASS ATTENDANCE MONITORING SYSTEM
Here in this system, we are allotting unique RFID code with every student identity card. When any particular student has entered into the class for attending any lecture, at that time he has to swipe his RFID card with RFID reader which is present at the door of classroom. If students details are matched with attendance monitoring system database then only that students will be allowed to enter in that classroom and he will be marked as present in the attendance system for that particular lecture.
AUTOMATIC HOME DOOR CONTROLLING VIA RFID SYSTEM
This is automatic home door controlling via RFID system. Here, every family member is having RFID key tag that when placed on door, the door will be opened and the indicator LED will glow and the camera placed on front door take a snapshot at that instant to keep record. Here, the RFID key tag send serial data to RFID reader placed on door to perform controlling operation.
RFID BASED AUTOMATIC TOLL TAX SYSTEM
In this project RFID Based Automatic Toll Tax System, RFID tag is placed on front mirror of the car. When car is passed through tollgate, automatically through RFID system toll tax will be deducted from car owner’s bank account. This system is very useful for tollgate management as well as it is used to avoid hotchpotch at tollgate.
RFID BASED WATERPARK SPORT BILLING SYSTEM
This is very innovative and unique RFID Project. Currently it is working in almost all water parks. By using this system, customer has to pay one time for all sports available in that water park. His payment amount will be stored in his RFID card. So, whenever he will play some sport game in park, the particular game entry fee will be deducted from his card. At the end, whatever, balanced amount present in his RFID card is returned back to him. In water park ,It becomes hectic for customer to keep money because of water sports. Hence , this RFID card based billing system is used over there to avoid mess in the park.
