Issue material by scanning, not typing

A handheld app that lets operators issue material to work orders and move stock between locations by scanning, with first-in, first-out lot control and a full audit log.

The problem

What was getting in the way

  • Issuing material to a work order meant walking to a terminal and keying the work order, operation, part, quantity and lot.
  • Each keystroke was a chance for a wrong lot or a wrong work order, which undermines first-in, first-out and traceability.
  • Transfers between locations had the same problem, and there was little record of who moved what.
  • Work order travelers differ from site to site, so a one-size-fits-all screen did not work.

How we solved it

What we built

  • A handheld app where the whole happy path is scanning: badge, work order traveler, part, then a rescan to confirm.
  • The traveler barcode carries the work order, lot, split and, at one site, the operation, so the app can jump straight to the correct requirement line.
  • For traced parts the app shows a first-in, first-out lot list and requires a scan of each lot label, so the wrong lot cannot be issued.
  • Transactions post to the ERP through its API, and every scan is written to a log table for audit.
  • A location transfer flow follows the same scan-first pattern.
  • Each site runs the same code with its own connection and traveler format settings.

How it works

Zero taps on the happy path

Badge

The operator scans their badge to sign in.

Traveler

Scanning the work order barcode loads the job.

Part

Scanning the part finds the requirement line.

Confirm

A rescan confirms the quantity to issue.

Lots

For traced parts, scan each lot label in first-in, first-out order.

Screens

On the handheld

Large targets, one action per screen, and a scanner button as the main input.

What changed

The difference on the floor and in the office

Nothing to key

Scanning replaces typing, which removes a whole class of keying mistakes.

First-in, first-out enforced

The lot list is ordered for the operator and rejects the wrong label.

Full audit trail

Who issued what, to which job and from which lot is recorded for every transaction.

Faster at the point of use

Material is issued at the shelf or the machine instead of at a desk.

Fits each site

Traveler formats and system connections are configuration, so a second site reuses the same app.

One app for issue and transfer

Operators learn a single scan-first pattern for both jobs.
