Hi, I'm an electronic engineer with more than 5 years of experience in Arduino programming. Actually, I have decided to apply for this project because I have previous experience in using the same RFID reader with Arduino and I also came up with the same problem of working with multiple RFID readers. At the time, I had to use 4 RFID readers and it didn't work in the same SPI line. SO I had to develop a bit banging SPI library to connect multiple RFID readers. So I can help you with this project using my solution. Actually this solution will use more pins on Arduino, and more wires, but it is the only solution I can see with this RFID reader. I have the library implemented, and I can make the code work with this. I'm available to work on this project right away and looking forward to hearing back from you. Thank you Anusha

Hello We have been an engineer for more than 8 years in the market and have already developed projects for several companies using microcontrollers like PIC, AVR, Arduino, ARM, NXP, Nordic, Texas among others. Using the general description of your project is possible to make a generic estimate, but the refinement of the total amount of work and the value of it will depend very much on the quantity and complexity of the features to be implemented, so I look forward to your contact for more details. Thank you. Elton Vieira

I already played with multiple RFID and the issue is that if you put more than 3 module at the same time it’s going unstable. The easiest solution I found is to put 2 arduinos handling all the RFID and exchanging information between them. I’m on mobile right now so I don’t have access to your png or zip but everything could be done easily.
