I had the same problem with the WiFi tabs I broke one of them and that was a bigger problem than nfc. My solution was to create a ball of solder on the connection for the tab and then stick the broken tab onto that ball of solder it took a bit of trial and error to get the height right as the tab will no longer spring. My WiFi now works but not quite as well as it used to. I think its because the impedance of the solder is greater than the bronze tab.
