Bwang,
We will try and answer each of your questions.
First, Yes GETLinked Software will enable you to extract daily sales data from Micros 3700. With the POSLink module (Daily Sales Summary) GETLinked Software specifically imports the "Definitions" created within the Micros 3700 64 Tracking Groups (ex. Dining Room Sales, Room Service, Bar, Visa, MasterCard, Discounts, Sales Tax, etc.) and the transaction dollars that correlate to these Tracking Groups.
Second, we did email you information on "data polling" as well as some links here with related Forum topic discussions:

A common way customers copy data between their point of sale and timeclock systems to their financial systems are free programs such as "Dropbox". You can read more about it here:
Data Polling Overview.
There are many other similar programs such as SugarSync , ShareFile, Syncplicity, Qbox and more.
Thank you for the post.
