There are even books about Android + Arduino. In your case you don't need Arduino if that RFID/NFC reader is the only device you want to plug in. USB/Bluetooth UART dongle is all you need (for serial communication). hm......... if you use NFC enabled phone or tablet then you won't need that RFID/NF...

I see serial RX/TX on it. If it has all the features you need you can handle it even with the tablet using USB or Bluetooth UART adapter if you want to write an Android app... if on Raspberry then you can VNC the desktop to laptop or use something like Atrix Lapdock (HDMI screen, touchpad, keyboard...

It would be quite simple to create an application that could accept a pin from the user to allow access.

Thanks for the suggestion, however I'm looking for something a little bigger, perhaps a 7 inch screen.

Basic RFID readers emulate keyboards. If you keep focus on a form field reading the tag will print its ID into that field and submit the form. Backend web application can then check if the code is valid and can be granted access :) Thanks riklaunim, I had already purchased the Adafruit PN532 NFC/RF...

It isn't too clear what you have in mind but have you looked at WebIOPI? I came across WEBIOPI awhile ago, but can it be integrated with RFID door tags? Basically instead of a physical hard keypad to punch in a PIN number, I would like to use a touchscreen keypad that will interact with the Pi for ...

Tablet can SSH into RPi, or use another serial connection via USB or Bluetooth UART. Then you would get the terminal on RPi. Some VNC application would allow getting desktop on RPi. This is an option, thanks. I thought about this and wanted to be sure when someone looks at the tablet they don't kno...

Hi, Suggestions, comments are welcomed. [joke mode on] Your message reminds me to a local leader of a political party - he talks something, you don't know what and why, but you feel that he doesn't know much about the subject and is afraid this to be found out. The worst thing is that he expects yo...

Hi all, I'm trying to see how I can go about interfacing a robust soft keypad to the Raspberry Pi for pin access. I'm open to suggestions, but thought a $125 Android tablet would be a robust choice. I will be using the RPi as a master and Arduino as a slave. I am using an RFID scanner connected to t...

Did you ever get this to work?

Out of curiosity, did you get your solution configured?

Hey All, First time post here. I have an entryway that leads to 32 rooms. My idea is to have either a RFID key fob entry or hand print scan (I think the hand print will be overkill so for the explanation lets stick with RFID). On top I would like to have a display such as an iPAD or other LCD screen...
