When connecting for the first time, look carefully at the encryption type. If it has the letters "AES" in it, you're safe. Even the NSA can't crack AES encryption with a decent password without dedicating several months of supercomputer CPU time to it. For nearly 15 years it was completely uncrackable. Nowadays some holes have been found, but you need access to some serious computer hardware and a huge chunk of time to pull it off. A private hacker would pay thousands of dollars to access the cloud resources needed to do it on his own.
If the password is something stupid ("p@ssw0rd"
, or if it doesn't contain the AES designation, it's best to consider the connection untrustworthy. Treat it as if everything you do is visible to everyone around you...because it just might be.
And you may want to look into that e-reader thing. Depending on the service, your credit card may not actually be stored on the device at all. It may be stored on the servers of the remote store, which is actually safer for you than typing it in every time you need it.
As to your question...no, you can't be tracked if you're not online.
