Advanced Options

This page covers advanced features and options for ID Bolt that help optimize performance and handle specific use cases.

Keep Alive​

When running ID Bolt multiple times in sequence (such as scanning multiple passports in a batch), you can improve performance by keeping resources alive between sessions:

// first scan
let idBoltSession = IdBoltSession.create(ID_BOLT_URL, {
  // other options...
  keepAliveForNextSession: true
});

// second scan

idBoltSession = IdBoltSession.create(ID_BOLT_URL, {
  // other options...
  keepAliveForNextSession: true
});

// more scans...

// When finished with all scans
IdBoltSession.terminate();

Benefits​

  • Faster loading times for subsequent scans
  • No need to request camera permissions again
  • Reduced resource initialization overhead

Important Notes​

  • Always call IdBoltSession.terminate() when done with all scans to release resources
  • This feature is most beneficial when scanning multiple IDs in quick succession
