The RFID cloner program is very useful for me, cause other ready programs cant copy the data at same memory locations in different cards, but your programs does. Thanking you :) :) :)

Nice job man, I used your DoorCode to unlock Windows 10... Thank's

Nice!!

When stating the rfid serial number can you define it in hex as well or just decimal in order for it to work ?

@farahammar7442 6 років тому

Hello, thanks for tutorial! I'm looking for help: I have a project with arduino uno + barecode reader +RFID tag. I want to read this barecode in arduino and send it in the RFID tag . How can i do this?p

@Lifestand749 4 роки тому

Thanks for making this Tutorial. Would you please asnwer my 2 questions. Which is the maximun storage capacity of the White Card and the Blue Tag?. I noticed that you speak about 1Kb of Storage Capacity and i just wanted you to tell me if all Cards and Tags have the same Storage Capacity or if its possible that this capacity changes on other models. Thanks for your time.

There are bigger ones on the market

@atmel9077 8 років тому

I made a "lock" which can store some credit information on the card's memory and uses authentication.

How to add multiple tags in a program of rfid. Please tell me

@ionut.666 6 років тому

Hello! At 3:08 you say that every block can store 2 bytes of data. What I see there is that every block can store 8 bytes of data because each pair of hex values is worth 8 bits, which means 1 byte, and we have 16 such pairs (16 such bytes).

@logmaker3609 6 років тому

sharp mate!! Thanks its a while ago that I was into this... Its not 2 bytes indeed but 4 (64 / 16 = 4) Thanks

Can I connect this to the rasbperry pi 3 b+ and write a card?

@karlmanubag6044 5 років тому

Hello, two of my cards can open the door. The first three hex numbers are different but the fourth one is the same. I'll just state it because maybe you missed this bug(?).

I cant read my home entry fob info with rc522, can you tell me why is it so? different frequency? if it is so how to play with my home entry fob?

@swapnilborage4020 5 років тому

Small correction plz.. each block stores 16 bytes data not 2 bytes! As there are total 64 blocks, total memory will be 64 blocks * 16 bytes per block = 1024 bytes = 1kB card memory..

@Ghost572 3 роки тому

I know when I heard it said each block stores 2 bytes, i was looking at the memory diagram thinking the hell it stores 2 bytes. You can literally count each byte when its displayed on the Arduino serial monitor.

@daliaabdelmoamen1179 2 роки тому

Hello Sir, I have some questions, Sir. Do i have to learn some programming language to write at the rfid? If so, can you please tell me which? Is the program available on the internet? Is the program attached in the link in the description of the video is only applied for MF522 rfid or it can be written at any other type? Thanks a lot

@logmaker3609 2 роки тому

In this video the language is Arduino, that is C based but simplified. Have a look on my changel for more in- deep Arduino

@Jawirjawara87 5 років тому

just a couple of question : can arduino store transaction data into database (such as mysql) ? I am just wondering that this can be used for gate controller in amusement park, so whenever people tap the card then data is stored into database in the server.

@logmaker3609 5 років тому

prasatyo adji Sure thats possible. In combination olther other processors. There are good tutorials about sql and arduino online. Shortcut would be to store the data on a SD card. I made a video about that one on my changel

@logmaker3609 4 роки тому

Yes, write a script in Python or Bash that read out the data and ping the web with it

hello, am new for this rfid module. am directly connecting the module to pc without any controller. by using wake up command and scan command i found the uid number. now i want to access the 1k memory. can you please send the command list.

@yofatim123 3 роки тому

Hello, nice tutorial. I just couln't find how you added your tag id.In you video you have ID D2 70 C075, but in the code I see: byte knownTac[4] = {04,226,83,219}. When I add my tag id inside the 2 brackets, I cad an error when compiling, beause the tag id contains alphanumerical digits, but it should be only digits. Can you explain ?

@johncunningham1201 3 роки тому

He converted the ID from Hexadecimal to Decimal. I had this confusion at first too.

Hallo, Ik heb dus een nfc chip/rfid chip in mijn hand en wil graag de data van mijn pasje (waar je de deuren van mijn werk mee kan openmaken) hoe kan ik dit doen?

@logmaker3609 7 років тому

wat bedoel je met de data? Bedoel je de unieke code die jou toegang verleend. Of de data die een log maakt als je de deur opent met jou chip?

@oshpelomochacha5740 5 років тому

wow thank you! hoped a lot. can u tell me how can i cope the chip to be the same as the other one i have?

@logmaker3609 5 років тому

Its not a good idea to programme 2 identical chips. Rather you authorize another id for the same task

Is there any way to write URLs into the tags with this device?

@joost9522 4 роки тому

did you succeed? I had the same question

@johnsharpe4809 4 роки тому

@@joost9522 I ended up using and android phone and an NFC app to write URLs onto the card. I have a theory that you if you just use your phone and write the URLs on the card with you phone, then you could copy the code from the phone and paste it on the arduino IDE. I haven't tested it though. Let me know if you have questions. Learned a lot through this project.

@AlexanderHL1919 6 років тому

How fast (minimum contact time) can the reader read tags? If I have fixed beacons, and a reader attached to a moving robot, how fast can it move over the beacon and still make a successful reading? Thanks :)

@logmaker3609 6 років тому

The one in the video is slow, about 6 seconds for a full read. But do your homework and buy a fast one. Read the specs (;

@ezequielblanco8659 6 років тому

It's pretty fast. I don't know how fast is your robot, but I have 6 cards in a cardholder, and if I swipe it above the reader in less than 1 second, it still manages to read them all. So if you just want to read the UID, 0.17 seconds should be enough. Cardholder is similar to this: sxmrhino.com/wp-content/uploads/2017/11/business-card-holder-plastic-sleeves-With-gro%C3%9Fartig-creativity-Plastic-perfectly-design-13.jpg

@AlexanderHL1919 6 років тому

Cheers for the info. That sounds promising. I ordered one but havent got it yet, but I figured, I'll just have minimal info on it, even down to 1 bit for the purpose of robot confirming that it reached that position and have a counter function in the arduino code to keep track of how many beacons it ran over, rather than keep the info of which beacon is which on the beacons. Cheers again :)

@giorgiobrugnone6879 3 роки тому

Wow...i figured out in a strange way. If at the end of write and read i put this mfrc522.PICC_DumpToSerial(&(mfrc522.uid)); it works any time Really strange....

rfid is not connecting with arduino plz help me ..i tried changing the rc 522 and changed the programme. ..but still its show there is some error in connection between reader and ardunio plz help i have a project to be submitted soon

@logmaker3609 7 років тому

What is the error?

@TwinOfTheGemini 6 років тому

I've connected everything but it won't read the card at all, everything is supposedly connected accordingly to the arduino uno and even changed the pins accordingly yet I can't even run dumpinfo because it won't read anything :(

@MrApplefreaker 6 років тому

Check your soldering. I had the same problem.

@logmaker3609 6 років тому

strange, probely your device is corrupt;(

@TwinOfTheGemini 6 років тому

Thanks for the advice, it was actually the reader came with a fabric fault, so it didn't read at all.

It was! The reader has a malfunction, but thankfully I had a second one and got it to work! ^^
