I did enough research on reading RFID tags using Android phones(smart phones).

My understanding of this is that for NFC-enabled smart phones (Nexus S) it is possible to read RFID tags, but there are restrictions.

For non-NFC-enabled Androids we need a RFID reader to which we can communicate from Android using Bluetooth.

My question is:

  1. What are the SDK which we use for reading RFID tag from Android Phone(NFC enabled)?
  2. If I have to read using Non NFC enabled phone, is there any standard reader available who provides SDK for development purpose?

You can hijack your Android audio port using an Arduino board like this. Then, you have two options (as far as I'm concerned):

1) Buy another Arduino Shield that supports RFID. I haven't seen one that supports UHF so far.

2) Try to connect your Arduino hijack with a USB RFID reader and build some embedded hardware kit.

Right now, I'm working in the second option but with iPhone.
