Module Introduction:

 This module adopts HID technology, foreign trade quality, driver, and comes with an application program in the download materials, plug and play. Supports WIN7, XP 32-bit, and 64 bit systems, making it easy and convenient to use. We provide application programs and C++secondary development library code. There is no VB code, but they are all DLL files. Therefore, whether it is possible to operate on VB requires friends who are familiar with VB to try it out themselves. Due to engineers pursuing further studies abroad, we are unable to provide you with technical support. Therefore, please review the information before taking photos,

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
