Once uploaded, scans can be deleted via the[Scans page on CodeREADr.com](https://www.codereadr.com/knowledgebase/filter-scan-records/). ### Allow users to edit answers saved on-device Enable this feature to let users modify data collection answers saved on their devices. Note that data cannot be edited after uploading. ### Allow users to view other users’ scans - Share scan data across users in real-time. Scans will appear in the History tab of the app. - Privacy Considerations: Enabling this will make all scans visible to all users, and they can edit or delete scans regardless of ownership. ### Allow users to edit online scan Grant users the ability to edit scans after uploading them. For maximum flexibility, combine with allowing users to Edit Answers Saved on Device. ### Forbid users from backing up scans on-device when connectivity fails Prevent users from saving scans when connectivity is lost. This forces users to maintain connectivity or contact a manager. ## Service Duration ### This service should only be active for a limited duration Limit scanning access to specific dates. Useful for events or time-bound projects. Users will not see the service outside the defined duration. ![Set Service Duration](https://www.codereadr.com/wp-content/uploads/2016/02/service_duration_normal.png) ## On-Device Features ### Duplicate scans on-device are INVALID Enable this option to prevent duplicate scans on the same device. Ideal for offline scenarios. ### Manual Sync Users manually upload scans and refresh the database. ### Auto Sync Automatically upload scans every two seconds and update validation databases every two minutes. Requires active internet connectivity. [Learn more about Auto Sync here](https://www.codereadr.com/knowledgebase/auto-sync/). ### Email me when on-device scans are uploaded Receive emails containing records when scans are uploaded from on-device services. ### Postback each on-device scan uploaded to a specified URL For developers: Send each scan to your server or validate against a custom database. [Learn more about Postback URL services](https://www.codereadr.com/knowledgebase/postback-url/). ## Capturing Settings ### Alter Scan Value Extract and record specific parts of scanned data using predefined patterns. Ideal for driver’s licenses, IDs, and asset tags. [Learn more in our article about Alter Scan Value.](/knowledgebase/alter-scan-value-and-response-text/) ### Alter Response Value Customize the displayed response after scanning based on patterns. Useful for tailored user experiences. [Learn more in our article about Alter Response Value.](/knowledgebase/alter-response-value/) ### Auto-Next Scan Streamline scanning by automatically reopening the camera or advancing fields after valid scans. Configure delays or stop for invalid scans. - Single-Line Mode: Auto-advances to the next field. - Multi-Line Mode: Requires manual navigation for multiple entries. ## Camera and Scanning Options ### Do not automatically reopen camera after each scan Prevent the camera from reopening after scans, directing users to the Tap to Scan screen instead. ### Disable Camera Scan, Manual Scan, and/or Lookup Disable camera scanning, manual entry, or [database lookup](https://www.codereadr.com/knowledgebase/scanned-unscanned-data/) as needed. Perfect for using external scanning accessories. ### Enable Kiosk Mode Lock the device to a specific service. Users can only scan within the designated service. Customize branding and instructions for an optimal user experience. [Learn more about the Kiosk mode for barcode scanning here](/knowledgebase/kiosk-mode/). ## GPS Tracking ### Collect or Track Device GPS Location without interruption as a property with each scan Track device location during scans for accountability. - Background Tracking: Records location automatically. - Appends a GPS data coordinate to scan record’s Properties Visualize scans on a map using tools like Google’s My Maps. [Learn more about importing scans to My Maps](https://www.codereadr.com/blog/google-mymaps-asset-tracking/). ## Display and Validation Settings ### Enable custom web view for lookup and history Customize the Lookup and History sections for tailored displays. ### Enable custom display configuration [Modify the appearance of response screens](https://www.codereadr.com/knowledgebase/customized-scan-response/) to enhance user experience. ### Enable on-device custom validation Use JavaScript to [create advanced validation rules](https://www.codereadr.com/knowledgebase/custom-validation/) based on barcode data, response text, or user inputs. ### Enable Hybrid Validation Hybrid Validation combines both online (cloud-based) and on-device validation to offer flexible data verification. [Learn more about Hybrid Validation here.](https://www.codereadr.com/knowledgebase/hybrid-validation/) ### Enable the PRINT option [Integrate printing capabilities](https://www.codereadr.com/knowledgebase/printing-from-app/) using Mobi Print for seamless workflows. By following this guide, you can fully optimize CodeREADr’s advanced settings to meet your scanning needs while enhancing usability and maintaining data integrity.
