Not necessarily! CodeREADr's barcode scanner works with barcodes in any form, including: - Small, dense, damaged, or partially obscured barcodes - Poorly printed or angled barcodes If you're having trouble scanning, our [SD PRO advanced scanning engine](https://www.codereadr.com/knowledgebase/sd-pro-scan-engine/) improves accuracy. Alternatively, if you'd like to create digital IDs, we recommend using [ID123](https://www.codereadr.com/blog/scannable-digital-id-cards/). No barcode? No problem! With the Lookup feature, you can search an associated database and create scan records without physically scanning anything. ### Can CodeREADr create ID credentials for students or employees? While you can generate barcode values and images on CodeREADr, most users opt for [a third-party ID creation service](https://www.codereadr.com/blog/announcing-zapier-integration/). Here's why: - CodeREADr focuses on verification rather than credential provisioning. - You can [manually create a database](https://www.codereadr.com/knowledgebase/creating-a-database/) or [automatically upload a database of ID values](https://www.codereadr.com/knowledgebase/auto-import-data/) for seamless integration. ### How can I track who is accounted for and who isn’t? The [Lookup tab](https://www.codereadr.com/knowledgebase/scanned-unscanned-data/) in the app makes it easy to sort individuals by their scanned or unscanned status in real-time. ### How do I prevent duplicate check-ins? Enable [Duplicate Checking](https://www.codereadr.com/knowledgebase/validate-barcodes/) to alert users if a barcode has already been scanned, ensuring accurate attendance records. ### Can I display photos or emergency contact info with ID scans? Yes! Using our [Webify feature](https://www.codereadr.com/knowledgebase/how-to-use-webify/), you can associate a photo and additional details (like emergency contact information) with each ID. These details will display when a barcode is scanned. ### Can I manage separate groups or roles in the app? Absolutely! Organize your data in several ways: - [Create separate databases](https://www.codereadr.com/knowledgebase/creating-a-database/) for different groups or roles. - Assign unique services for each list of participants. - [Set up separate user accounts](https://www.codereadr.com/knowledgebase/creating-a-user/) for each teacher, manager, or location. - Alternatively, you can use one database and export segmented data to a spreadsheet for organization. ### Can I customize the app’s appearance? Yes! You can: - [Personalize the response screen](https://www.codereadr.com/knowledgebase/customized-scan-response/) (e.g., [change the message](https://www.codereadr.com/knowledgebase/alter-response-value/) for invalid IDs). - Add your company logo with free or paid [white-labeling options](https://www.codereadr.com/knowledgebase/branding-and-customizing-the-app/). ### Does pricing depend on the number of IDs? No, [pricing](https://www.codereadr.com/knowledgebase/paid-plan/) is based on the number of devices used, not the number of IDs scanned. Key details include: - Unlimited scans on all paid plans. - A device is counted as billable when a user signs in on it during a billing cycle. - The count resets monthly, and unique device logins are counted toward your plan limit. ### Do I need special hardware for scanning? CodeREADr works seamlessly with most devices, including: - iOS and Android smartphones - Mobile computers While CodeREADr doesn’t sell hardware, you can choose devices that best suit your needs. [Check the device requirements for CodeREADr here](https://www.codereadr.com/knowledgebase/device-requirements/). ### Can I use the app without an internet connection? Yes, [CodeREADr supports both online and offline functionality](https://www.codereadr.com/barcode-scanner/work-offline/): - Online: Enables conditional validation and cross-device duplicate checking. - Offline: Allows you to download a database and verify IDs without an internet connection.
