Barcode Web Scanner Web Barcode Scanner runs on Android and iOS phones without needing installation of any Apps. It scans only on the phone ensuring maximum privacy.

1. Barcode Format

1D Barcode formats currently supported:

  1. Codabar
  2. Code 128
  3. Code 39
  4. Code 39 VIN - use for Vehicle Identification Number
  5. Code 93
  6. EAN-8
  7. EAN-13
  8. EAN Extended - use for serial books EAN13 + UPC5
  9. Interleaved 2 of 5
  10. Standard 2 of 5
  11. UPC-A
  12. UPC-E - compressed UPC-A

Default barcode format is EAN-13.
The older UPC-A format, still in common use, is automatically converted to EAN-13 by adding a zero "0" in front.

2. Barcode Size

For trouble free scanning, barcodes should follow the relevant standards e.g. EAN-13 barcodes should have the following:

  1. Minimum Width 26mm
  2. Minimum Height 19mm
  3. Minimum Left and Right Clearance 3mm
  4. Top and Bottom Clearance 3mm is preferred but not required.

3. Camera Use

Barcode images should be

  1. Landscape Mode (image width longer than height)
  2. Large and Clear (imaged zoomed in and sharply focused)

If the phone camera performance is poor, the web scanner can alternatively accept images from other sources (e.g. SMS, Bluetooth, AirDrop etc.) uploaded from the phone's file system.

Rapid Antigen Test

There are many Lateral Flow Test (LFT) or Rapid Antigen Test (RAT) available e.g. 18 with very long and confusing names in Australia and there are different types under the same brand (e.g Oral, Nasal, Saliva), it is very difficult to enter the correct one when taking the tests - especially if you are travelling overseas.

The Virtual Vaccine web app:

has integrated web barcode scanner:

So the correct rapid antigen test type used can be recorded accurately every time.

The default UPC-A barcode format is used for Rapid Antigen Test, but it can be changed on a per country basis.
