how can i store the output of arduino in cloud using bluetooth connection

how can I store the output of Arduino in the cloud using Bluetooth connection to an android smartphone?
what I want to achieve here is I want to scan for RFID tag, I want to read only its uid and with respect to that, I want to store some data in the cloud. can I connect it to a smartphone and then receive the data from Arduino.

You should ask this question in an Android forum as it's almost unrelated to Arduino. The only thing from the Arduino world you have to know is the USB2Serial chip that is used. As you failed to tell us the Arduino model you're using we even cannot help you with that topic.

By attaching an Ethernet Shield to it and following one of the many tutorials you find on Google.

You might have to think about what "the cloud" means for you as that has implications on the search terms you have to provide to Google.
