One solution might be to install a pullup resistor on the processor's MISO pin, then connect that pin to the SD and RFID pins through diodes - oriented so that either module can bring the line low, but neither can force it high.

One solution might be to install a pullup resistor on the processor's MISO pin, then connect that pin to the SD and RFID pins through diodes - oriented so that either module can bring the line low, but neither can force it high. I found a solution for using both RFID and SD card module, I simply put a 330Ohm resistor between MISO line of SDcard and they are working. Another solution is to use second Arduino and communicate with Softwareserial to send command and .
In this project you’re going to build a time attendance system with MFRC522 RFID Reader and Arduino. When you swipe an RFID tag next to the RFID reader, it saves the user UID and time in an SD card. It also shows if you are late or in time accordingly to a preset hour and minute.
Learn how to use RFID NFC RC522 with Arduino, how to connect RFID-RC522 module to Arduino, how to code for RFID/NFC, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on .
In this project, we will make RFID MFRC522 based Time Attendance System Using Arduino Board. When you swipe an RFID tag next to the RFID reader, it saves the user UID and time in an SD card. It also shows if you are late or in time accordingly to a preset hour and minute. For this, we are interfacing the MFRC522 RFID SPI module with Arduino.
Upload the code to your Arduino Uno. Once uploaded, open the Serial Monitor (set the baud rate to 9600) to see the RFID card's UID when you scan a card. Step 6: Testing Your Access Control System. Power up your Arduino, and scan an RFID card. If the card's UID matches the known UID, the LCD will display "Access Granted" and "Welcome!". An RFID system needs tags and a reader: Tags are attached to the object to be identified, in this example we have a keychain and an electromagnetic card. Some stores also use RFID tags in their products’ labels to identify them. Each tag . This blog post shows a simple example on how to use the MFRC522 RFID reader. I’ll do a quick overview of the specifications and demonstrate a project example using an Arduino.
can't figure out how to wire up the RFID and SD card module to an Arduino Mega! This would be the RFID that you "have the RFID reader and keypad working together"? SD cards are read from/written to using SPI. Arduino IDE. Project description. Why did we decide to make it? Attendance in University is generally paper based which may sometimes cause errors. Taking attendance manually consumes more time. So, In this project we have designed RFID Based Attendance System using Arduino and RFID MFRC522 Module.

But this does not work. I think it doesn't work because the script used for different .Using this, a pass in Passkit can emulate an NFC Card. BUT: You can only use this with an NFC Pass Type Identifier or what it is called like. I am from germany and know skidata and their way of thinking and love it! This technology of using a pkpass is very nice - but you need that nfc .
