- Hello Friends,
In this video we are talking about the RFID. How it works? How to read unique codes of it?
RFID means Radio Frequency Identification, it is short range communication technology. The term RFID is used to describe various technologies that use radio waves to automatically identify people or objects. RFID technology is similar to the bar code identification systems. It consists of reader, antenna and tag. RFID tags support a larger set of unique IDs than bar codes
An RFID system consists of transceiver, which read the radio frequency and transfer the information to a processing device (reader) and a transponder, or RF tag, which contains the RF circuitry and information to be transmitted.
When an RFID tag passes through the field of the scanning antenna, it detects the activation signal from the antenna. That "wakes up" the RFID chip, and it transmits the information on its microchip to be picked up by the scanning antenna.
In addition, the RFID tag may be of one of two types. Active RFID tags have their own power source; the advantage of these tags is that the reader can be much farther away and still get the signal. Even though some of these devices are built to have up to a 10 year life span, they have limited life spans. Passive RFID tags, however, do not require batteries, and can be much smaller and have a virtually unlimited life span.
RFID tags can be read in a wide variety of circumstances, where barcodes or other optically read technologies are useless.
Radio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 7 cm away.
This RFID Card Reader can be used in a wide variety of hobbyist projects and commercial applications, including
Access control, automatic identification, robotics navigation, inventory tracking and payment systems. The RFID card reader read the RFID tag in range and outputs unique identification code of the tag at baud rate of 9600. The data from RFID reader can be interfaced to be read by microcontroller or PC.
Features of it are
• Low-cost method for reading passive RFID transponder tags
• 9600 bps serial interface at 5V TTL level for direct interface to microcontrollers & LED indicate valid RFID Tag detection
• Range up to 7 cm for 125 KHz RFID Cards or Key chains
When the RFID Card Reader is active and a valid RFID transponder tag is placed within range of the activated reader, the unique ID will be transmitted as a 12-byte printable ASCII string serially to the host in the following format:
Start Byte
(0x0A)
Digit 1 Unique ID
Digit 2 Unique ID
Digit 3 Unique ID
Digit 4 Unique ID
Digit 5 Unique ID
Digit 6 Unique ID
Digit 7 Unique ID
Digit 8 Unique ID
Digit 9 Unique ID
Digit 10 Unique ID
Stop Byte
(0x0D)
When powered on the RFID reader will activate a RF field waiting for a tag to come into its range. Once tag is detected, its unique ID number is read and data is sent via serial interface.

Good info about RFID, thanks sir
Always welcome
kon kon se projects is RFID se ban sakte hai.
bahut sare projects ham bana sakte hai like Attendance System, Smart Library, Smart Shopping Trolley, Door Lock etc.
Hello sir I have a arcade / game zone card that works exactly like this you give the cashier the card and give money the amount of money you give he puts that amount of credits so if I want to put credits from my computer how can I do it it works exactly like this rfid card thing
Hi, you need one GUI to connect with RFID reader. GUI software fetches the code of RFID and whatever amount you will assign it, it will take in records. Same will be applied to your machine.
@@TheTiaraTechShow how much dose one of them cost and do you need a seprate software to change amount
@@Cytopyte with single software you can change amount and reconfigure the card.
CAN YOU TELL ME THE NAME OF THE SOFTWARE THROUGH I CAN CHNAGE THE DATA OF THE CARD EXAMPLE CHANGE 0 CREDITS TO 100 OR 1000
@@TheTiaraTechShow AND WHICH RFID READER SHOULD I BUY WHICH I CAN CONNECT TO MY COMPUTER
Hi sir I have one code but I can't upload multiple card's please solve the issue
Do you want to add more RFID Cards in your code? Kindly go through this

Follow this steps
First detect the unique codes
Store it at Array or EEPROM
After that compare all the 10 digits for performing any specific application.
