Shenzhen Xingtong IOT Technology Co., Ltd.
Barcode Scanner Manufacturer with development & Invention ability

Access control terminals increasingly use QR codes alongside cards and passwords. Visitors may receive a temporary QR code on their phones, while employees or contractors may use printed access passes.
The XT738M allows equipment manufacturers to add this scanning function directly inside the terminal.
XT738M supports QR codes displayed on mobile phone screens as well as codes printed on paper or access cards.
It can be used to read:
Visitor QR codes
Employee QR codes
Temporary access passes
Appointment and reservation codes
Printed entry tickets
The scanner decodes the code and sends its content to the customer’s mainboard. The access control system then checks whether the code is valid and decides whether to open the door or gate.
XT738M is supplied as a bare scanner board rather than a complete desktop scanner. It can be installed behind the scanning window of an access control terminal, visitor registration device or turnstile reader.
The compact board design allows the scanner to become part of the finished equipment without adding an external scanner housing.
XTIOT supplies the XT738M scanner hardware and communication commands. The customer’s software manages QR-code generation, identity records, access permissions and door-control logic.
For project evaluation, customers can send clear photos of their actual QR codes and information about the terminal’s installation space. XTIOT can test the codes and confirm whether XT738M is suitable before ordering.
Can XT738M read QR codes from mobile phones?
Yes. It can read supported QR codes displayed on phone screens.
Can it also scan printed access passes?
Yes. It supports QR codes and compatible barcodes printed on paper or cards.
Does XT738M control the door lock directly?
No. It outputs the decoded barcode data to the customer’s mainboard. The customer’s access-control system handles verification and door operation.
Does XTIOT provide access-control software?
No. XTIOT supplies the scanner hardware. The customer develops or integrates the system software.
