Why doesn't scanning work or why does the scanning screen close automatically?

If your scanning functionality isn't working or the scanning screen closes automatically, it’s likely due to an incorrect license key configuration or trial mode limitations. App ID mismatches and improperly formatted keys are two common configuration issues: 

  • Application/Bundle ID Mismatch: Make sure your application's application ID (Android) or bundle ID (iOS) precisely matches the ID you registered with your license key. Licenses are tied to the specific application identifier provided during key generation. 
  • Exact Key String Input: Enter the license key string into your application exactly as we provided it. This includes all line breaks, special characters, and trailing characters. Even a minor deviation invalidates the key, impairing or terminating the SDK's functionality. 

If you're not using a full license, you may be encountering trial mode limitations. 

  • The examples in our API References run in a 1-minute trial mode without a license key. All SDK functions are active during this minute.
  • Once the 1-minute trial period ends, SDK functions stop working. UI components, like the scanning screen, may also close. To resume trial functionality, simply restart the application for another minute. 

Extending Your Trial

Need longer scanning sessions for evaluation or development? You have several options. You can generate a free, no-strings-attached 7-day trial license from our website for extended functionality. Or reach out to our Sales team to request an extended Proof of Concept (PoC) license, which offers a longer evaluation period tailored to your specific needs.
