Barcode Plotter

Barcode Plotter — POS Item Plotter Barcode Plotter is a fast, offline barcode generator and on-screen "plotter" built for retail, point-of-sale (POS) testing, inventory checks, demos, and training. Load a list of codes from a simple text file and the app renders crisp, scannable barcodes right on your screen — one after another on a timer, or on a single tap — so you can test scanners, POS terminals, and workflows without printing a single label. Whether you're a developer validating a checkout system, a store owner testing a new scanner, or a trainer running a demo, Barcode Plotter turns your phone or tablet into an instant, reusable barcode source. ✨ Key features • 13+ barcode formats — Generate EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, ITF, Codabar, QR Code, Data Matrix, Aztec, and PDF417 from the same data file. Switch formats any time from Settings. • Plot from your own data file — Pick any text file of codes (one value per line) using the system file picker. A built-in sample data set is included so you can start instantly. • Auto-cycle or manual — Press Start to automatically cycle through your codes at a configurable interval (default 5 seconds), or tap the barcode to plot the next one on demand. Pause and resume anytime. • Sequential or Random mode — Plot codes top-to-bottom in a continuous loop, or pick them at random — perfect for varied test runs. • Crisp, scannable rendering — Barcodes are drawn at full resolution so real scanners read them reliably straight off the screen, with proper quiet zones. • Export to PDF — Generate a clean, paginated A4 PDF of all your codes with one tap. Each page includes a titled header with date, a 3-column table (serial number, value, barcode), neat separators, and page numbering — saved straight to your Downloads folder. • Modern, distraction-free UI — A sleek dark dashboard puts the barcode front and center, with live value, barcode type, status, and a running counter. • Helpful feedback — Optional sound cues for refresh, clicks, and errors. • Always up to date — Built-in Google Play in-app updates keep you on the latest version. 🛒 Great for • Testing POS systems, checkout software, and barcode scanners • Validating inventory, warehouse, and stock-control workflows • Generating printable barcode sheets (PDF) for labels and reference • Product demos, QA testing, and staff training • Developers building or debugging scanning features 🔒 Privacy first Barcode Plotter works entirely on your device.
