Answer: Walter thought the chip was real because he placed it under a scanner and the scanner confirmed that the chip was real. However, given the fact that later on it was revealed that the whole plane sequence was a set up, it is probable that the device used to scan the chip was actually a fake that was used to make Walter believe the chip was real, most likely throw him off guard.
