They took photos of us, but no fingerprints. We both received our cards. I wouldn't worry. If the officer let you in and processed your files, then it should be okay. They don't use the fingerprint nor the photo from the airport for producing the card. I suppose you had your fingerprints taken at the consulate.Is there anyone who already entered the US for the activation but neither had your photo nor finger prints taken at the airport?
I started to worry as the officer who was in charge seemed to be an apprentice.
He said it was the first time for him to stamp on a passport page..
If you are still worried. You can try calling USCIS and tell the robot, that you need infopass appointment. That will connect you to an agent. Then you can ask the agent, if he sees that your documents arrived to USCIS properly and if everything is okay with your cases, they are able to check this for you. If the agent doesn't want to help because of whatever reason, I would try again to get a different agent. Mine was very helpful.
Also, when you logon to Myuscis it should have a Submitted on: xxxxxxx line, just under your case Subject. If that date is a date after your entry, then most probably your documents have arrived to USCIS properly on that date.
