Tutorial:Using a RFID Card Reader with the Arduino

[@Spix_Weltschmerz-Pucket]

This worked perfectly for me
Arduino uno r3 + Funduino RFID RC522
I bow down to the makers of this! Thank you so much!

[@Makecourse]

Thanks! Appreciate it! visit makecourse.com for more info!

[@Spix_Weltschmerz-Pucket]

Make Course BTW, I have a problem reading a card...it tells me the ID number, but in the dump shows PCD_Authenticate() failed: Timeout in communication.
Any clues?

I think this is the best video about rfid systems. thx for sharing :)

[@beehive808]

Great Video, Thanks for help me understanding the right way to program the Arduino and using other hardware.

[@tegumembra7528]

Very good job, it helped me so much. Thanks very much otherwise I wouldn' thave been able to succeed in it. With an ArduinoMega card you should match the :
MISO with 50
MOSI with 51
SCK with 52
SDA (SS) with 53

Thank you for your work, and the info, esp. with the source code link via Github.

Worked perfectly with my MF-22. Well done! Thanks. Cheers

Thanks you so much i made a multifunction lock that uses the MIFARE authentication instead of the serial number and it can learn or delete cards without using a computer and the authentication key can be set.

hi there, I'm new to this RFID stuffs. I'm using a msp430 microcontroller, any hints to the codes for the msp? Thx!

Hello...
can you help me please?
I want from RFID sensor to count five cards and after this condition is completed I want from the microprocessor(on Arduino board) to operate another task.
can you tell me please how to do this ??

[@NurulIslam-ij8ns]

may i use two diffrent white card as master and slave,the key ring tags are not available here.

[@ram_psara]

help me out...
how to find the 12 digit number of the rfid card...
i couldn't get that..
thank you...

[@okiook]

Where can i find the write / read code ?

[@isaaccavalcante]

Hello. Great work. This help me very much. I have a problem, please help me kkkk. I have made that in ReadandWrite code:
byte sector = 15;
byte valueBlockA = 63;
byte valueBlockB = 5;
byte valueBlockC = 6;
byte trailerBlock = 63;
So DumpInfo no longer works. I tried run the default ReadandWrite code, but still no longer works. What can I do?

[@kristerstudsgaard]

thank you so much for sharing!!

[@sagarsharma7265]

I am using a fresh card and in dumpfile not getting anything

[@newspapergames140]

I know the video is old, but I need help please. I have this problem PCD_Authenticate() failed: Timeout in communication. I Can't write in the tag. Can someone help me?

[@TLeonT]

same did you found any result ?

[@giahuy473]

try increasing the baud rate more than 9600

[@Xbox360addict1000]

Does this work for the Arduino Genuino Uno?

[@thomashvnmusic]

My RFID is the same as your but is missing the SS from it. Any help anyone?

[@leandro0gs]

Try using the SDA...

[@thomashvnmusic]

Leandro Gomes da Silva I found a work around so no worries but thanks anyway.

[@CLTsang]

Thomas Heaven can you share what the work around is? thanks

[@أحمدشلبي-ض3ث]

can i take the code please

[@darknesskillerpt4196]

Can you give me the arduino code plz man?

[@cortezscott2534]

Can someone build me one
