Kingtech QR code display is used for dynamic generation and display of QR code. It adopts 3.5 inch 480x320 IPS full-color screen display. Users can send QR code data to the display according to the agreed protocol through the USB port or serial port and display. The screen will be automatically generated and displayed (the QR code display position is left/right/center selectable, and supports English/symbol and Chinese character display).
The refresh rate of the QR code on the display screen is fast, and it can support batch updates of the QR code in turn. Built-in RTC in the system can provide an automatic time stamping function and digital signature authentication function to ensure that authorized users can update the QR code data. It can be widely used in WeChat QR code collection, hotel QR code unlocking, electronic business card display in exhibitions, etc.
Kingtech Display, one of the most famous LCD display panel manufacturers in China, has achieved great progress in the field of LCD production. Kingtech promises that we will provide the customers with qualified standard LCD display and satisfying one-stop services. Any requests will be welcomed.
The aim of this project is to create a QR Code Displayer using the Dot One. QR codes enable you to share information such as Wi-Fi credentials, URLs, contact information or just simple plain text with anyone that has a camera on their phone.

Lately I have been scanning a lot of Quick Response (QR) codes required because of government check-in/out during the COVID pandemic. I was curious to understand what this barcode was and whether it was feasible to generate one using simple MCU hardware and display it on an ePaper display.
QR codes were invented in 1994 by the Japanese automotive company Denso Wave (who still retain the trademark) to track vehicles during manufacturing and allow high-speed component scanning.
Because it could be read quickly and could contain more information than a standard UPC (one dimensional) barcode, it quickly became popular outside the automotive industry . The advent of cameras on consumer devices like mobile phones helped to further spread QR codes as convenient a method of encoding and accessing information.
A QR code can encode just over 4000 alphanumeric characters in a square grid of black squares arranged on a white background. This makes them relatively easily recognized by an imaging device such as a camera. The data is extracted from patterns that are present in the horizontal and vertical components of the image. The pattern encodes data using Reed-Solomon error correction code and up to 30% of the message can be reconstructed using this encoding.
The Arduino qrcode library by Richard Moore is a derivation from a code base maintained by Project Nayuki, who seems to have a real passion for these codes.
The library was able to convert arbitrary data into a QR code on an Arduino Uno much faster than I had expected, given how complex the task actually is. The generated data is stored in an internal data structure and accessed through the class interface.
The next step was to display this data on an ePaper display. I already owned a WaveShare 2.9″ ePaper display. This display uses an SPI-like interface (CLK, DATA, SELECT) for communications and has a resolution of 128 by 296 monochrome pixels. My version runs on 3.3V and needs a level converter between the Arduino Uno I/O pins and the display. More recent versions (labelled v2) have a converter built into the display.
The library I used for the ePaper display is GxEPD2, which works with many different type of modules and uses the Adafruit GFx libraries to generate text fonts and graphics.
The sketch became a matter of ‘gluing’ the two libraries together. I decided to allow the user message to be encoded to be typed at the serial monitor to make it easier to test different messages.
The core code for the sketch used can be found below, excluding the standard hardware selection header for GxEPD2 (GxEPD2_display_selection.h) which follows the template in the library examples, and will depend on your specific hardware.

The elegant touch screen self service ticket collection digital signage kiosk is another man-machine interaction station, super thin metal housing design with several components inbuilt orderly under the screen, it looks very smart, the postion of those spare parts can meet human body very well, user can use smart phone to scan the payment QR code to pay, and the automatic touch screen kiosk with print ticket automatically for him or her to take away, it just need several seconds to finish the payment process, no need anybody else to help, also user can use the membership card to pay via the NFC card reader, which has ACR 122U model, support ineract with database of any software which support this function.
he new QR code "rMQR Code", which enables printing in long, narrow spaces, can also be read. This expands the range of applications. (To read rMQR, update the firmware to the latest version.)
In May 2014, we set up Everbest Photoelectric, which is the predecessor of Jinjia Optoelectronic Dongguan factory, specializing in the production of TN / HTN / STN / VA LCD products. Mainly to undertake overseas customers export orders.
The RT400 is a 2D (QR code, pdf417, Datamatrix,...) barcode reader which readable bar codes from phone screen and other LCD display, readable from paper, too. Ideal for mobile ticket(e-ticket, e-coupon ) bar code reading.Electrical
