Here is an NFC reader app using Cordova/PhoneGap based on ChariotNFC. I am using it to read tags from TouchATag.
I made it for the Samsung Nexus S. I updated it to Ice Cream Sandwich Android 4.0 via an Over The Air update through Sprint.
To see more how you can use NFC, check out this Adobe MAX Video.
Here are some pics:
