RFID EXPLAINED: HOW TO WRITE DATA TO RFID CARDS WITH ARDUINO

[@eddiemendoza7353]

How would you turn those numbers in the 02 line as alphabet letters when you scan that card - like it would show what 74 means when translated into an alphabet?

[@MikaelAbehsera]

its been a bit since this video but if I remember correctly its hex code, so the program just converts our indivitual characters into hex code and inputs that into the card storage (if its not hex its some other method but same idea)

Hello, how to run power down mode in both Arduino and RC522? By bringing the card close to the RC522 module and using the interrupt mode in both modules, the system is started and after running, it goes into power down mode twice to extend the battery life. If this is not the case, the battery will run out in two weeks. set_sleep_mode(SLEEP_MODE_PWR_DOWN); in arduino and mfrc522.PCD_WriteRegister(MFRC522::CommandReg, 0x10); in rc522

My RFID isn't compactible with the arduino uno. It always gives communication error. what might be the cause?

[@rlclips9497]

​@MikaelAbehsera is there a way to write info on the 15th row block. If this is possible it would make the scanning process so mich faster

[@MikaelAbehsera]

Not sure actually, never tried

[@medmnoomane9126]

if possible code source thanks

where's the esp32 part?? the pins are different

[@MikaelAbehsera]

just check a pinout for esp, but most of the time its the same except for 1-2 pins

[@donotprikel]

No ive tried LOTS of cards and even the ones that come with arduino and they dont write but only read

[@icrosstheline6903]

Me too. I have wayyy too many tags and cards that were advertised as writable which are readonly

[@MikaelAbehsera]

hmmm, seems weird, check your wiring on the write cables, could be an issue there

How to encode picture in contactless chip?

[@MikaelAbehsera]

Well it had to be max 1000 bits

[@khalidmehmood6545]

@@MikaelAbehsera i have 4Kbytes contactless chip.

[@vijayprasad9850]

Can i read and write with my iPhone

[@MikaelAbehsera]

Maybe? If you can edit code on it

Please make a video on how the security and the authentication works on NXP - Mifare DESFire EV1

[@MikaelAbehsera]

I’ll take a look and see if it’s something we can cover

What’s the point of this video? You’re just showing default examples
