The same station scan field changes purpose while an item is being checked. Read its current label before entering another value. This reference supplements [Scan components](/manuals/kitproof/scan-components) and [Serials, lots and quantities](/manuals/kitproof/serials-lots-and-quantities).

## Scan and capture fields

| Field or control | What to enter | Checks and limits | If it is refused |
| --- | --- | --- | --- |
| Scan or type a component barcode, then Enter | An exact part alias admitted by the frozen kit plan, or its permitted bin card. | At most 128 Unicode characters, non-empty, with no ASCII control characters. Matching does not trim, change case or convert a number. Each accepted allocation counts one item. | Check that this component is required in this kit and at this point in an ordered plan. A similar alias or a component whose required quantity is already filled does not count. |
| Serial number for the named component | The actual serial label for the component just offered. | The same 128-character bound and exact spelling apply. A component alias in this kit plan or a bin-card code is not a serial. The same component-and-serial pair cannot be owned by another kit at this site, or have a second active allocation in this attempt. | Check the physical serial and ask the Supervisor to investigate an existing claim. Do not add a suffix or remove leading zeros. |
| Lot number for the named component | The actual lot label, separate from the component barcode. | The same 128-character bound and exact spelling apply. Component aliases in the plan and bin-card codes are refused as lot values. A lot may repeat across items. | Check which label you are scanning. The component does not count while its required capture is still missing. |
| Choice of requirement after an ambiguous component scan | The displayed requirement that this physical item is intended to satisfy. | The offered component must be eligible for the selected outstanding slot. A slot selection does not change the component or create another item. | Read both requirement names and remaining counts. If neither describes the intended use, ask the Supervisor rather than selecting a convenient slot. |

A bin card encodes KP1:BIN: followed by its exact component identifier. It counts only where the frozen plan explicitly permits that bin scan and records bin-scan evidence. A KP1: kit reference other than a bin card belongs to opening a kit; it cannot be used as a part scan in the current kit. Finish or pause the current kit before opening another.

## Finish each trace capture

A serial or lot capture waits for up to five minutes. If both are required, KitProof keeps the captured serial while asking for the lot. The item counts only after the necessary captures have been accepted. If the prompt expires, scan the component again and supply the requested values; do not assume an unfinished prompt has allocated it.

For example, a slot needing four clips starts with four outstanding. Two accepted component scans leave two. Entering a required lot after a scan finishes that item; it is not an additional component scan. Read the updated remaining quantity before presenting the next item.

## Request an exact exception quantity

Where Request exception is available, choose the permitted kind. If both kinds are offered, the prompt asks for exactly manual_quantity or waiver. Enter a positive whole number in How many, no greater than the displayed outstanding quantity, then give a non-blank Reason for the supervisor of at most 500 Unicode characters. Cancelling a prompt sends no request.

Manual quantity is unavailable for a serial-required slot. A pending or approved request of the same kind for the same slot prevents another such request. Read the existing request before trying again. An approved manual quantity or waiver is retained as an exception disposition; it does not invent scans. An approved alternative instead requires the component to be scanned again. Continue with [alternatives and exceptions](/manuals/kitproof/alternatives-and-exceptions).
