Look for a combination of clues

Start with the in-game Augmented Identification Guide and Mentor Note. They describe things to notice, not a single appearance that makes every customer an Aug. A walkthrough reproduces the handbook and customer encounters so you can compare the wording with the game. [1]

What to observe—and what the observation can tell you
Check Possible clue How to use it
Visible features A visible chip, unusual eyes or facial expression Compare several features with the handbook; do not turn a clothing style or one face into a permanent label.
Movement Unusual stillness or twitching Observe the visitor instead of deciding from one frozen frame.
Speech Mechanical or unusually formal phrasing Read it alongside the appearance and behavior.
Aug Scanner A scan result for the current visitor Use a powered scanner and read its output. Suspicion and a completed scan are different states.

For the visual reference itself, open the handbook and encounter images in the source walkthrough. The table above summarizes the checks; it is not a substitute for inspecting the actual visitor. [1][2]

Why “Threaten (Aug)” does not identify one

This is the most useful distinction to keep in mind: an available action says what you can try, while a scanner result says what the device reported. Seeing the action does not establish the customer’s identity.

Confirm before choosing a response

  1. Compare the handbook clues. Keep a suspicious visitor separate from a confirmed identification.
  2. Check your scanner. Follow its item requirements and power it before use.
  3. Scan the current customer. Read the result. If you have no functioning scanner, do not treat a guess as a scan confirmation.
  4. Use the actions available in that situation. A weapon shown in one encounter is not proof that it can be equipped at any moment. [1][2]

The Mentor Note warns that Augs can interfere with security communications and escape. Calling security should not be described as a guaranteed solution to every Aug encounter. [1]

This reference does not establish a fixed spawn day, a universal scanner energy cost or a guaranteed reward. Check the item and encounter you are actually dealing with.
