Scan Recognition

Scan an item barcode to quickly update its stock quantity without navigating to the detail page.

Feature Overview

When items are already in your inventory and have barcode labels attached, you can use this feature to quickly stock in or stock out:

  • Scan and act: Scan a barcode and the quantity adjustment panel appears immediately
  • Quick stock in: Add item quantity, record incoming stock
  • Quick stock out: Reduce item quantity, record consumption or shipment
  • One-step operation: No need to enter item detail page — scan and done
Difference from Barcode Scanning

Barcode Scanning (in the add button menu) is used to create new items by fetching product info from the network.
Scan Stock In/Out is used to update quantity of existing items in your inventory.

How to Use

  • Open Scanner

    Tap the scan button (QR code icon) in the bottom right corner of the home page

    Point the barcode on the item toward the scan frame

Optional: add a note such as "restock" or "gift to friend."

Stock In/Stock Out Toggle

Use Cases

Warehouse Inventory Check

When you have many items in a warehouse with barcode labels:

  • Scan barcodes during stocktaking to quickly locate items
  • Directly adjust quantities and record stock changes
  • No need to enter detail pages one by one

Restocking

When new stock arrives:

  • Scan the item barcode
  • Select Stock In, enter quantity and price
  • One tap to update inventory

Item Checkout

When lending or selling items:

  • Scan barcode to find the item
  • Select Stock Out, enter quantity
  • Add a note for buyer or destination

Daily Consumption

Update stock after using consumables:

  • Used some items? Scan their barcode
  • Select Stock Out and reduce the quantity
  • Always know your remaining stock

Works with Printed Labels

Scan Stock In/Out works best when combined with printed item labels:

  • Print labels (with barcodes) from the item detail page
  • Attach labels to items or shelves
  • Later, scan barcodes to quickly stock in/out
Recommendation

For items requiring frequent quantity updates (warehouse management, inventory checks), we recommend printing barcode labels and attaching them to items. This makes scan operations most efficient.

When Item Not Found

If the scanned barcode doesn't match any item in your inventory:

  • You'll see "No matching item found"
  • The barcode may not have been added to your inventory yet
  • Use "Barcode Scanning" to create a new item entry

Share Code Recognition

The scan feature also recognizes share codes (starting with maozla):

  • Scanning a share code directly opens the item detail page
  • Or opens a filter view to see related items
  • Useful for receiving item info shared by others

Common Issues

Can't scan?

Try these solutions:

  • Ensure sufficient lighting, avoid shadows
  • Hold phone steady at a moderate distance
  • Make sure barcode is flat without creases
Why show multiple items?

If several items in your inventory share the same barcode (e.g., you bought the same product multiple times), a list appears after scanning so you can choose which one to operate on.
