HID sends scans as keyboard input. SPP provides a serial-style connection for compatible Android applications. BLE requires the application to support the scanner's BLE protocol. Confirm the supported mode for the selected model.

Can I connect a wearable scanner to an iPhone or iPad?

Use a supported Bluetooth HID or BLE setup. For BLE integration, confirm that the application implements the required protocol. Do not assume an Android SPP workflow also works on iOS.

How do I scan into a Windows application?

With a supported Bluetooth HID configuration, pair the scanner with Windows and place the cursor in an editable field. The scanned data is sent like keyboard input.

The scanner is connected but no barcode appears. What should I check?

Check the communication mode, the active input field and whether the barcode symbology is enabled. An SPP or BLE application must establish the required communication channel.

Can I configure Enter, Tab, prefixes and suffixes?

Use the settings in the exact model and firmware manual. Supported characters and configuration procedures can differ between models.

Can EF02, NS02 and T3 read screen barcodes?

Their 2D scanning configurations can typically read supported codes on phones, tablets and computer screens. Performance depends on the engine, code size, brightness and reflections.

How do I choose the scanning engine?

Match the engine to the barcode type, code density, label condition and working distance. Provide difficult sample labels and the required distance so the appropriate configuration can be tested.

How should I plan EF02 or NS02 battery changes?

EF02 and NS02 use a replaceable-battery design. Prepare compatible spare batteries for shift rotation. Runtime depends on the configuration and workflow; confirm whether a battery change interrupts the connection.

Are multi-slot charging options available?

EFFON offers multi-slot charging solutions. Confirm the charger that matches the selected scanner or battery. Do not assume charging while scanning is supported by every model.

What should I check if a charging slot does not work?

Check seating, power and charging contacts. Swap compatible scanners or batteries between slots to determine whether the issue follows the device or the slot. Contact support if it persists.

What should I do before cleaning an NS02 glove?

Remove the scanning module, battery and other electronic parts. Follow the supplied glove-care instructions and allow the glove to dry fully before reinstalling any electronics.

Can the NS02 glove be replaced separately?

The NS02 scanning module and glove are separate. Inspect worn gloves and replace them with compatible accessories. Glove life depends on handling, friction, environment and cleaning.

Why does my T3 stop sending data when the phone screen turns off?

Check the phone's power and background-app restrictions. For a compatible Android app, an SPP workflow may be suitable if the app supports background SPP communication. Confirm and test the actual setup.

What if the T3 does not charge or respond to the scan button?

Check battery charge and seating on the charger, clean the charging contacts as instructed, and restart the device. If the scan engine still emits no light or the controls remain unresponsive, contact EFFON support.

Why does the Bluetooth connection keep dropping?

Check battery level, range, nearby interference and host power management. Confirm that the scanner is not reconnecting to a previous host and that the app is allowed to run as required.

What customization and support are available?

Discuss logo, packaging, SDK and integration requirements with EFFON for the selected model. Provide the serial number and software details for technical support. Confirm warranty terms separately for the scanner, battery and wearable accessories.
