In this era of rapid digital development, small QR code modules are quietly changing the way we interact with technology. These small and powerful QR codes can not only store a lot of information, but also connect seamlessly across multiple platforms. Next, we will take a deeper look at how small QR code modules work and explore their wide range of applications in various fields.

Small QR code modules are two-dimensional barcodes that can be read by smartphones or other devices equipped with cameras and QR code scanning software. Its functions are as follows:
1. Fast scanning: The small QR code module has the ability to quickly identify and decode, and can achieve high-speed scanning even in complex environments, ensuring that users can quickly obtain encoded information.
2. Error correction: The QR code module has powerful error correction capabilities. Even if the QR code is partially damaged, defaced or blurred, the data can still be accurately decoded to ensure 

3. High-precision decoding: The module can read high-density encoded QR codes, and the decoding is still accurate even if the QR code is small in size and contains a lot of data.

4. Low power consumption: The small QR code module is designed to be energy-saving and suitable for application scenarios with strict power consumption requirements, extending the service life of the device.

Small QR code modules have been widely used in various industries due to their excellent flexibility. Here are some common application areas:
1. Retail and e-commerce:
