How to build a Cafeteria Smart using RFID Card?

Radio Frequency Identification technology uses radio frequencies to target objects. Almost every industry uses it around the globe.

Using the RFID cards students can enjoy the services of the cafeterias. To give an effective solution we are going to discuss, How to build a cafeteria smart using RFID card?

RFID or Radio Frequency Identification is a wireless form of communication.

This device uses the electromagnetic field so that the user can automatically identify objects and can also track animals and birds.

RFID is based on the AIDC principle. AIDC or Automatic Identification and Data Collection are use for data transmission, but the only drawback is it contains wire communication.

We can say that RFID is the advanced version of AIDC technology.

There are three main components of RFID that are RFID Tags, Antenna, and Readers.

RFID Tags – Each tag is a combination of the microchip and antenna. It has information about the asset.

RFID Reader – It is the key source of RF energy. The RFID reader is used to activate and power the passive tags.

Antenna – It contains the radio waves that are used to transfer the information from the reader to tags. 

Due to numerous benefits of RFID integrated with the cafeteria system. 

• There is no need to cash all time
• No need for pocket money from parents
• Send SMS to parents about food taken by the student
• Online monitoring of student’s eating habits
• Eliminate the human error in accounting
• Reduce paperwork

In traditional Cafeterias, there was a cash payment system. The drawback of the older cash system is to manage the paper-based record. 

When the RFID Reader introduces in the college or university’s cafeteria, then it improves the accuracy and efficiency of the whole canteen system. 

• When the RFID tag is get detected from the reader/writer module, then the microcontroller recognizes whether the person is a valid user or not using installed data.

• Now users can access/her account and get the facility of ordering food they can collect very easily.

• During this process, if a user has an insufficient balance in the account, it displays the message “Kindly refill your account”.

• With the help of a wireless transceiver, the signal will be sent to the owner of the cafeteria for preparing the ordered food. That is how the RFID system works in the cafeteria. 

Reduce Human Error 

Manual work will generate some errors. Using RFID, data can be read automatically, so there are no chances of error. Data can be updated automatically using RFID technology.

Managing inventory and tracking products

Using an RFID reader you can track and manage the inventory system. This system can be helpful in a reliable way to track the stock of a product and update it in real-time. 

Reduce processing time 

RFID enables the system that helps colleges cut costs, improve subscriber service, reduce labor, and increase precision in the system. 

Higher productivity

Using the RFID technology, cafeteria owners can increase their productivity. Because it will reduce the processing time while making payments and taking orders. 

There are two main challenges while using the RFID technology:

Reader Collision

When the two signals of the reader get overlap, then Reader Collision occurs many systems are using anti-collision sites. 

Tag Collision

RFID tag collision occurs when the tag is president in a small area and it gets. Tags are difficult to remove because sometimes it is hidden or inside the product. 

RFID – smart radio solutions are the keystone of emerging the Internet of Things (IoT) in modern cafeterias. The current trend indicates that the market of RFID POS (point of sale) will ascend faster.

Also, business applications using RFID are expanding rapidly such as retail, supply chain, manufacturing, travel, agriculture medicine, etc.

It is a giant step ahead for the World Wide Web, where RFID readers and tags are everywhere and everything is connected to the Internet. It would be beneficial for businesses and consumers also. 

If you are planning to make smart cafeterias across the country. So you need to implement the smart RFID cafeteria system across the college and universities of the country.  

The RFID payment method is using radio frequency technology so that cafeteria owners can differentiate the valid & invalid users. Moreover, they can store their data securely.
