The SyncSign APP version was created for the purpose of small business owners using SyncSigns digital signage panels to change the panel location and change product information (out of stock/price change, etc.) through the APP.The purpose and function of each screen are as follows.(1) On the login screen, you can log in through the issued ID/PW. However, there is no membership registration function (because the master issues a member ID/PW at the time of becoming a customer of Commerce Lab), only the ID/PW search function exists.(2) On the My Panel screen, you can check the screen being broadcast from the logged-in users store, and the key function of the screen is to change the content location of the installed panel in the store. (Example: Move position from panel 1 to panel 3)(3) The purpose of the product management screen is to change the product image displayed on the panel, out of stock processing, and option values (price, tag, etc.).
