How do you integrate RFID?
In the RFID system, each tag can only communicate with a reader. By integrating RFID tags with nodes, communication of the RFID tags with each other is possible and also integration of readers with nodes facilitates negotiation of readers together.
7 magnificient uses of RFID
- Car rental: No-waiting vehicle returns.
- Amusement parks: No-swipe ticket passes.
- Casinos: Robbery-proof chips.
- Sports: Loss-resistant golf balls.
- Guns: Safety products.
- Smart fitting rooms.
- Health care: A hygiene solution.
What information can be stored in RFID tag?
RFID tags have a memory chip installed allowing storage of an item’s; location, serial number, manufacturer, photo, use history, a maintenance schedule and much more. The speed of this data capture using an RFID system is less than 5% of the time taken in a manual process.
Can a microcontroller read a passive RFID tag?
RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology. To read the Passive RFID cards and tag, we need a microcontroller with UART hardware.
There are three types of RFID tags available, Passive, Active or Battery-assisted passive. Different kind of RFID tags with a different kind of shapes and sizes are available in the market. Few of them use different frequency for communication purpose. We will use 125Khz Passive RFID cards which holds the unique ID data.
What do you need to know about RFID cards?
RFID ( or Radio Frequency Identification ) is a method which uses radio waves to capture electronically the data present in RFID cards or radio labels. The RFID module consists of an antenna and a microprocessor. Nowadays they are used in many sectors like nuclear.
Before interfacing RFID with STM32, first we will learn about RFID tags and RFID reader. RFID tags are made up of a microchip with a coiled antenna that can communicate with a nearby reader wirelessly. Different kind of RFID tags with a different kind of shapes and sizes are available in the market.
