Este sitio es no tiene nada que ver con las anteriores marcas, solo pretendemos difundir el Hardware Libre. i have readers 0 and readers 1, and two variables count0 and count1, remember the readers faces each others, so i put one tag in the middle of reader0 and reader1, if the reader 0 scan the tag, count0 will increase to 1 and if reader 1 scan the tag in the SAME TIME it wouldn’t be counting because the reader 0 has scan that tag.but in my case, the readers(0 and 1) didnt response if i put the tag in the middle of readers.and for this project the data count0 and count1 i send it to nodemcu using SoftwareSerial(5,6).Im new for using Arduino and i still learn about it(i dont understand too much)You could ditch the code for reporting to the serial monitor (so no debugging code and no interaction with the serial monitor on the PC) and only use the LCD for displaying information.
Anybody can answer The Overflow Blog It only takes a minute to sign up.i have a project that use two RFID Reader, the project for counting tag from conveyor belt, in this case the reader will placed in the middle of the conveyor belt and the reader faces each other.So i have question, can two RFID Reader reading one or many tag simultaneously?

This would be my preferred way.mfrc522 is not as common any more, but if you want to use them rather then rdm6300 (more expensive device, but cheaper tags), then you can by Søren Thing Andersen (from It has been extended with functionality to alter sector 0 on Chinese UID changeable MIFARE card in Oct 2014 by Tom Clement (from Maintained by miguelbalboa until 2016.
