Bar code and OCR Trigger

IBM® Maximo® Visual Inspection Mobile can read bar codes or use optical character recognition (OCR) for use cases, such as reading serial numbers.

A couple of actions can occur after the bar code or text is read:

  • The bar code or text value can be sent over MQTT.
  • The value can then be compared to a rule that has a regular expression. If the bar code or text matches the regular expression, an inspection can be run by using the associated rule in the trigger string.

The bar code and OCR reader support multiple rules. Triggers can be sent to the same local device or to a secondary device by sending a trigger message over MQTT.

Note: When you use the bar code and OCR reader, the maximum image size that is uploaded is 1080 pixels.
The following bar code types are supported:
  • Aztec code recognition
  • Code 39 bar code recognition
  • Code 39 with checksum
  • ASCII Code 39
  • ASCII Code 39 with checksum
  • Code 93 bar code recognition
  • Code 93i bar code recognition
  • Code 128 bar code recognition
  • Data Matrix bar code recognition
  • EAN-8 bar code recognition
