Continuity mistake: In the first movie, when Dylan and Alma first meet up with Thaddeus Bradley for lunch, he mentions that Lionel Shrike was a magician in the 1970s and one year later, attempted the safe in the river trick that killed him, but in the opening scene of this movie, it is shown that the safe in the river trick that killed Lionel Shrike took place in 1984. (00:00:35)
Continuity mistake: When Daniel is communicating with "The Eye", he walks over to a well and places his phone down around the rim of it. The phone is beside the edge of one of the blocks covering the rim, to its left. When Walter is explaining to Daniel later on in the movie that he was the voice, the scene cuts to a flashback, and Daniel is now shown placing the phone beside the right hand side of the edge of the block. (00:06:05 - 01:10:55)
Continuity mistake: When Walter is explaining to Daniel he was the voice he heard earlier in the movie, he mentions that he put his phone on a by-wave syphon pad, the scene flashes back to when Daniel was communicating with the voice and it is discovered there was a device planted inside the well, shown behind a grid. When Daniel visited this place earlier on in the movie, the grid inside the well was visible, but there was no sight of the device inside the grid. (00:06:05 - 01:11:00)
Continuity mistake: In Dylan's first scene, he walks into a meeting room at the FBI and requests a minute with the director. During this, Dylan has a mug in his left hand and a file in his right hand. There is a long shot in this scene, with the shot several meters from Dylan, where the file is suddenly in his left hand. Then in the next shot of Dylan after that, the file is suddenly back. (00:07:20)
Continuity mistake: When Dylan is showing the FBI director and Cowan the photo of who may be Merritt McKinney, he is standing next to the director turned to the right, but in the next shot, the two are suddenly directly facing each other. (00:08:15)
Continuity mistake: When Dylan is showing the FBI director and Cowan the photos of the Horsemen, just as the FBI director asks what it all means, she is looking at Dylan, but in the next shot, she is suddenly looking at the photos. (00:08:50)
Continuity mistake: When Jack is showing Merritt how to throw cards, just after he throws the last card, Merritt says "Not bad" looking straight forward at the card, but in the next shot, Merritt is looking at Jack. (00:12:40)
Continuity mistake: When Merritt fails to throw the card, Jack says "it's good to be positive despite having made zero progress in a year" whilst looking at Merritt. In the next shot, Jack's head is suddenly turned about 90°. (00:12:50)
Continuity mistake: The banana that Jack takes from the woman at the metal detector when he is posing as a security guard at the OCTA launch is different to the one he plants in the CCTV guard's pocket a few minutes later. (00:16:25 - 00:18:30)
Continuity mistake: When Dylan and the Horsemen are infiltrating the OCTA party, Daniel is carrying a tray with four different lines of sushi. Daniel then walks into the hallway still holding the tray and the four lines of sushi and their position on the tray have suddenly been reversed. (00:16:55)
Continuity mistake: When Atlas walks in to the Octa phone launch disguised as a waiter he has a silver tray. Someone rearranges something on it as he walks down the corridor and it is plainly a silver tray. He walks through after the rearrangement and the next shot there is a briefcase visible under the tray. The tray is supposed to be a tray that becomes a briefcase but is too thin to do that. When first seen there is no space for the briefcase part to be closed up against the tray. (00:16:55)
Continuity mistake: When Daniel is trying to take the OCTA CCTV guard's ID pass, he takes a picture of him with a Polaroid camera so that he can stick it onto a tag to prove that he is from a mental hospital. When the picture prints out from the camera, all that is shown is shown is the image of the guard against a white background, instead of the wall seen behind him. Also, when Daniel takes the picture, the guard has his head turned to the right to face Daniel, but when the picture prints, the guard has his head positioned completely forwards. (00:17:40)
Continuity mistake: When the security guard at the OCTA launch finds the Evans Mental Facility wristband on the CCTV guard's wrist, the wristband and wrist are pointed away from the CCTV guard's face, but in the next shot, the wristband and wrist is directly facing the CCTV guard. (00:18:10)

Continuity mistake: When the Horsemen are exposing Owen Case at the OCTA party, as Lula says "He's mocked your privacy. He scorned it", she is standing facing the audience and is mostly covered in stage light. The shot then cuts to Daniel talking, and Lula, visible to the right of shot, is now standing facing Daniel and only half covered in stage light. (00:22:40)
Continuity mistake: When the Horsemen are onstage at the OCTA party, Dylan opens his iPad and notices a tarot card on it. In the close-up shot, when the tarot card is first shown, it can be seen slightly passing over the edges of the iPad, but in the shot previously, Dylan is opening the iPad, but the tarot card is nowhere in sight. It would have been visible even from the camera angle that was shown. (00:22:45)
Continuity mistake: When Walter begins hijacking the Horsemen at the OCTA launch, Dylan says "let's go to the back", and the FBI director tells him to stay here. There is a bald FBI agent standing in front of him to the right, but in the next shot, the FBI agent is suddenly behind him. (00:24:15)

Continuity mistake: When the Horsemen land inside the baskets in the Chinese restaurant, in the shot focusing on Merritt, Daniel is seen beginning to stand up, but in the next shot, he is suddenly lying back in the basket. (00:26:10)
Continuity mistake: When Merritt is explaining to Daniel, Jack and Lula that they are in China, he starts saying "I think where we are right now, they don't refer to it as Chinese food." In this shot, he is standing beside Lula, maybe a few inches ahead of her, but in the next shot, Merritt is suddenly a couple more feet ahead of her. (00:27:20)
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.
