I have an inconsistent internet connection . as well as I have nearly 15 transaction per hour . having that inconsistent internet connection is customer losing . Since I can do nothing about the connection , my best solution as far as I can see is to make the module partially offline . Same as what is used in POS . but I have really no Idea how to implement such function to my module since it is never been done before as far as my research told me at least for the projects that are available to be accessed .
So , What are your thoughts ?
thank you for your time
