In this tutorial we will learn what RFID is, how it works and how to make an Arduino based RFID door lock. RFID stands for Radio Frequency IDentification and it’s a non-contact technology that’s broadly used in many industries for tasks such as personnel tracking, access control, supply chain management, books tracking in libraries, tollgate systems and so on.

Hello, what software did you use to do the component and electrical schematic?

How do you get a Rfid sensor and key fob into Tinkercad or is there a substitute of these components that can be added into Tinkercad circuits?

[@chess1011]

How do you create beautiful diagrams? I mean specific software or websites you use for creating such diagrams. When it comes to ThinkerCad I can't find all the components, can you give some directions on this?

[@swayamraut119]

I want to make a similar project for my school science fair. Where do we have to place the proximity sensor, and do we have to keep it in contact with door when we close it? How did you hide all the wires you used? And did you place the arduino nano on the breadboard? Please do reply, your reply means a lot to me!

[@HowToMechatronics]

The proximity sensor is placed so that can detect when the door is closed. It doesn't have to be the particular model of proximity sensor, you could also use an HC-SR04 ultrasonic sensor for that purpose. All the wires are just wrapped with an insulating tape. And if you have the proper jump wires you don't have to use a breadboard, I didn't used. Have fun building your project!

Hello. I'm going to use simple MRFC22 RFID sensor inside a backpack, specifically on the backpack surface/layer. Is it possible to operate the RFID that way? Can the RFID sensor read the RFID tag through fabric? Thanks!

[@wiedhathecrafter7508]

God. Seeing someone explain what RFID is is amazing. Like, not so many people know what it is, and being a door lock server installer for Assa Abloy it hurts when people go, “oh, can I put that near my phone? It will still work right?” And I just want to look at them and go, “no, this can’t go near any electronics at all. If it does, the world ends.”

Thanks for the video I got question. How to implement in real situation, in order for us to come out from the room. Do you mind to share maybe some trick or reset button.. This method seems good for entering the room, but I am stuck when how the mechanism when we want to go out. Should we install both rfid sensor inside and outside the room? Tq sir

[@murentaotie4781]

hi, in your code ,if we add 100 cards, even if we delete all cards, tagsCount will not decrease, then we can't add any other card?

How the helmet detection on clg gate implemented using RFID?

[@jumbo999614]

What kind of card does this module support? I use my apartment keycard which is thicker and cannot be bent. Doesn't read. It reads only white card that comes with the package. And the blue thing with keyring only read for few lines then it shows this "PCD_Authenticate() failed: Timeout in communication".

Hi it was perfect I want to do different work I want open a lock with card But if i turn off the Arduino lock automatically open Actually i want a code that when Arduino is on lock should be lock and when put the card on scanner lock should open And when arduino is off lock should be open

[@InfinityAwaits]

Rfid doesn't send out a signal. Your initial screen shows it communicating by sending out a wave

Which language is used for coding

[@AhmadFauzi-pd2tb]

So the master card cannot be used to open the door.. am I right?? How to unregister the master card? Will double tapping the master card will unregister it?? Please answer... :)

Is the proximity sensor is optional or a must item?

[@HowToMechatronics]

It's just optional in my example.

[@athuldevadaz1494]

Wil you please upload a video which shows how we can stack books in a library and how we can identify them using a robotic arm

[@juancarlosabad3298]

you dont need to use a robotic arm to "identify" the books....if your RFID transponder (host side) antenna is big enough you can scan RFID within 8-15 m and that in batches of 300-400 RFID tags per batch, if you have more then sequentially without the need to be near nor point to the objects/tages...there are industrial handheld terminals or tablets which such integrated RFID large antenna...

[@kushagarwal3564]

Nice Video, but is the data stored on the EEPROM? What if I power down the system, will it still have the data?

[@julianp.2233]

There ar some systems that when the power goes off it will open.so if you are not home and a thief just closes the main citrcuit breaker the dor will be unlocked 😁

[@schancruz]

Hi! Can it be possible for a bag to be locked with an RFID tag? I'm planning to use it on our prototype making project. Hope you'll help! Thank you!

[@juancarlosabad3298]

what do you mean "bag locked"...RFID tags are available in multiple shapes and forms, one of them is as label that you can stick to your product which could also be a bag....you can even inject a glass capsule containing an RFID tag into your cat or dog , in some countries that is even mandatory..

[@juancarlosabad3298]

Error in the descriptin of RFID tag memory at minute 4:02 ....it says that the tag memory contains 16 sectors of 4 blocks each, so far so good, but then that each block stores TWO bytes of data when he obviously highlight two sub-blocks of 8 bytes each, so the the right interpretation is that each block contains 2x8=16 bytes ....so total amount of memory is 16x4x16bytes=1024bytes=1KB

[@metzgaming1650]

Bro tengo un problema con la pantalla lcd me ayudas?

[@assignmentable]

Hello, great video just a quick question about trying to make a relay stay on as long as the RFID card is present. So I want to make it so that I don't need to set a specific time duration the relay is on for. Is this possible with the RFID? just each time I leave the card next to the reader, it only reads it once, but I am unsure on if this is because of the code or hardware.

[@mallikatripathi4747]

How do you automatically close the door?

Sorry I have two noob questions. Is there any way (programming) to operate the lock as a simple lock, so disabling the "auto-lock" feature? I mean 1 card read operation to open the lock and one card read operation to close it. Because at home environment it would be a much more convenient way of operation. When I'm home I unlock the locks and when I leave I close them. And is there a way to control more lock from one "control box"? For example a house with 4 door. I would like to read my tag and unlock all the doors. Thanks!

[@steamfox]

What about RFID chip security? So many videos about RFID access control, yet so few mention anything about security.

[@AhmadFauzi-pd2tb]

SteamFox ,, from my understanding , there's no need for RFID security, because the mifare itself has a pre - implemented security system inside.. The cheapest mifare classic type has a crypto encryption inside, .. So unless you know keyA or keyB inside it .. you'll never get the access to modify each bit/byte of the data.. Cmiiw.. :)
