Configure receipt printing
Receipt printing uses the browser print path and branch receipt configuration; verify paper width and output before serving customers.Use receipt QR and invoice links
Receipts can include configured QR or invoice information, and public invoice links open through a tokenized route.Troubleshoot a barcode scanner
USB and Bluetooth scanners normally act as keyboard input and must send the full configured barcode terminator.Allow camera or microphone access
Camera recognition and voice notes depend on browser device permissions and remain optional POS capabilities.Use a scale with weighted products
A keyboard-output scale can fill the focused weight field; otherwise enter the measured value manually in the displayed sale unit.Understand terminal identity and heartbeat
TajerGo uses a stable local terminal identifier for shift and sync attribution, while current branch configuration controls enabled capabilities.Understand the POS device heartbeat
A configured terminal sends an automatic device heartbeat with online state, viewport, app version, and pending transaction count, using retry backoff when delivery fails.
