No, CodeREADr does not generate ID credentials. You must create and distribute your digital or printed IDs independently. Once created, you can [upload your ID database](https://www.codereadr.com/knowledgebase/creating-a-database/) to our server via our website, directly through our API, or by [integrating with a third-party service](https://www.codereadr.com/blog/announcing-zapier-integration/). You can also choose to create QR codes from CodeREADr once a database is uploaded. ### Are physical ID cards necessary, or can I scan a barcode from a phone? Our technology scans all types of barcodes and [RFID/NFC credentials](https://www.codereadr.com/knowledgebase/track-validate-rfid-nfc/), whether on physical cards or digital displays. This includes handling small, dense, damaged, or poorly printed barcodes, and even those at extreme angles. Our [advanced scanning engine](https://www.codereadr.com/knowledgebase/sd-pro-scan-engine/) enhances accuracy, especially in challenging conditions. ### What if I want to control vehicle access in a parking lot? [Parking permit validation](https://www.codereadr.com/blog/scan-parking-permit-barcodes/), a common scenario for access control, operates similarly to people access management but may involve additional considerations specific to vehicle access. ### What is the "Lookup" feature and its uses? The Lookup feature allows users to manually create a scan record for a barcode without scanning it. It’s useful if someone forgets or loses their ID. For added security, you can [disable this feature to prevent database access](https://www.codereadr.com/knowledgebase/service-advanced-settings/) by app users. ### Can I display a person's picture when scanning their ID? Yes. You can incorporate photos hosted remotely into your database using [Webify formatting](https://www.codereadr.com/knowledgebase/how-to-use-webify/). The scanned ID's response can display any associated personal information. ### Do I need someone physically present to scan IDs? Not necessarily. Our [kiosk mode allows for self-scanning using iOS and Android devices](https://www.codereadr.com/knowledgebase/kiosk-mode/), leveraging the front camera to enable hands-free ID verification. ### How can I manage re-entry with your app? For re-entry management, you can allow unlimited duplicate scans or use our [Check-In/Out service](https://www.codereadr.com/knowledgebase/check-in-out/) to track entry and exits, helping monitor attendee presence effectively. ### Can the app control entry based on specific conditions? Yes, [conditional validation](https://www.codereadr.com/knowledgebase/conditional-validations/) can customize access based on time, day, or other criteria, requiring internet connectivity for real-time data processing. ### Is it possible to add notes or ask questions post-scan? Absolutely. Enable our [Questions feature](https://www.codereadr.com/knowledgebase/collect-data-with-questions/) to collect additional information like names, addresses, and emails, or even capture photos during the scanning process. ### Can we generate detailed attendance reports? Yes, our [Scans page](https://www.codereadr.com/knowledgebase/filter-scan-records/) allows you to [filter, view, and export detailed reports](https://www.codereadr.com/knowledgebase/creating-export-templates/) on check-ins and check-outs, which can be further analyzed in [Excel or Google Sheets](https://www.codereadr.com/knowledgebase/direct-to-external-databases/). ### Can I customize the app's appearance and functionality? You can [personalize the response screen](https://www.codereadr.com/knowledgebase/customized-scan-response/) and[include your company’s logo](https://www.codereadr.com/knowledgebase/branding-and-customizing-the-app/) through our customization options, available in both free and paid plans. ### How is pricing structured? [Our pricing](https://www.codereadr.com/knowledgebase/paid-plan/) is based on the number of devices used rather than the number of scans. Each device signed in during your billing period is counted, with the total resetting monthly. ### What equipment is required for scanning? CodeREADr is [compatible with most iOS and Android devices and dedicated mobile computers](https://www.codereadr.com/knowledgebase/device-requirements/). No special hardware is sold by us; you can use commercially available devices or personal devices of app users ### Does the app work without an internet connection? Yes, [CodeREADr functions both offline and online](https://www.codereadr.com/barcode-scanner/work-offline/), ensuring reliable performance regardless of internet availability.
