I’ve just received my new Nitrokey 3A NFC.  
While the postal package seems to me untouched, the new Nitrokey has some traces of super glue (Sekundenkleber) and the housing isn’t completely closed, so you can see the pcb from the side.  
Is there any way to make sure the device hasn’t been compromised?  
Order-No: SO976405
