We recommend "Standard Edition" to those users who have less business (ex. end users, DIY users, repair shops with less business etc). Because this kind of user's have less business, when need to use advanced function, only recharge the corresponding "Credits Card", so as to easily ensure that each business can be profitable.

The "Credits Card" in your account no have time limit. Even if the balance of "Credits Card" in your accout is zero, it will not affect the use of your standard functions, because the standard functions are authorized once and are permanently free to use. In addition, any version of EMT can be updates synchronously.

TIPS: You can see functions detail of Standard Edition and whether the functions are payment via the "Function List"!
TIPS: The advanced function (Payment function) in the "Function List" will adjust at anytime according to the market!
