CodeREADr is an enterprise-grade barcode scanner and data capture app used by businesses and integrated by developers for capturing, validating, and tracking data (AIDC). Ideal for ticket validation, access control, inventory, asset tracking, logistics, attendance, security patrols, lead retrieval, coupon/voucher/loyalty programs, retail price audits, scan-to-order services, and more.

You can collect data with form fields, secondary scans, multiple-choice answers, drop-down menus, photos, GPS locations, and signatures. You can record and validate the data embedded in each scanned barcode and know who scanned (app usernames), what they scanned (i.e. barcodes, RFID/NFC, and OCR data), when they scanned (timestamps), where they scanned (GPS), how they scanned (capture type), and why they scanned (your configured workflow). Connect to 4,000+ apps to automate the flow of data to and from our servers. Connect to secure server in real-time with APIs and webhooks (Postback URL). Real-time and scheduled data transfer to third-party databases (e.g. Google Sheets, Excel, etc.).
