The F502 adopts the traditional 5.5-inch industrial grade full 

screen design, with lighter and thinner sides. The overall weight 

is less than 300g. The shell adopts a professional anti slip pattern

 design, and the back uses gray as the background color, which is 

not only durable but also dirt resistant. The equipment conforms 

to ergonomic design, making it easy to operate with one hand

The F502 has optimized the camera, improving image 

quality and clarity by 13 million pixels in the rear and 

2 million pixels in the front (with optional 5 million pixels). 

The image quality is visible and delicate to the naked 

eye, meeting the photography needs of users.

Users can configure NFC read and write functions, support protocols such as 

ISO14443A/B15693, and facilitate the expansion of more application 

scenarios, such as identity recognition and employee management
