Custom On-Device Validation

With our ‘Custom On-Device Validation’ (COV) feature, you can write your own JavaScript to validate based on the scanned barcode, the response text and the app user’s answers to in-app prompts. The service type must be a Record On-Device or Validate On-Device with manual upload to our server or auto-sync to our server (or yours).

• Decryption of encrypted barcode data, where app users can see the decrypted result in the response and becomes part of the scan record.
• Offline ‘A/B Compare COV’, where it alerts the app-user when two barcodes scanned in a row match or don’t match. To enable this, on the Advanced step when creating or editing a Service, copy and paste the A/B Compare COV script into the form field for ‘Enable on-device custom validation’. Also, this script allows comparing an ‘answer’ scan to the response text.
• Validate an answer to a pre-submit question against the response text in the associated database. Sample script here.
• Validation statuses over-written when certain criteria are met. For example, a normally valid scan can change to invalid based on:
  • the answer an app-user submits to a prompt (a “Question”);
  • when it detects certain text within the scanned value;
  • when it detects certain structured text within the standard response for the scanned value.

Please contact support@codeREADr.com with your specific requirement. For some applications, we will quote writing the script for you.
