This looks like a very nice option for the iPad. Would Linga work with these since you already work with other Magtek readers?

The option to remove included modifiers from displaying on the CDS. Feel that it takes up space especially since there is no cost for an included modifier. Only time the included modifier should appear is when it is selected to display the "NO" of that ingredient and or if a prefix is added such as "Extra." It shouldn't be removed entirely as some may want their ingredients to appear, but many do not. I am aware about the kitchen printer setting that removes included modifiers, which is good, this request speaks more to the CDS and or POS screen.

Have the ability to start a membership at any month, and have the renewal be monthly, quarterly, semi-annually, etc.

For example, if John Doe starts his membership in July, have it auto-renew October 1st (For quarterly).  Right now we are having to manually do the math to prorate memberships for when a new customer joins. 

I have customers using Facebook Pixel and Google Analytics and have suggested they would love to be able to track their customer bounce rate, their average page time, their click rate, and other metrics on their online ordering page. Combining this information with the new marketing campaign feature would really help drive engagement and sales. Maybe we could add a form field for the Google or Facebook campaign ID.

Ability to send messages directly to the Front of House iPads/Android devices from back of the house that can alert users with messages. 

We noticed lately that a customer can place an online order at 6:24pm to be picked up at 6:30pm. Because that is only 6 minutes that should not be allowed. The ‘rolodex’ clock should therefore default to ‘6:45 pm’ and allow us time to prepare the meal. There has to be a way to set your behind the scenes programming for the clock that when the time they are ordering is less than 15 minutes the clock should not allow them to order unless they select a later time frame.

We recently ran into a POS that was semi integrated with Pax S300 like Linga and they were able to auto populate the IP address of the Pax devices directly from the POS software. This would be a HUGE time savior and would make remote install and support much easier. 

When we asked about if they knew any additional info as to how this was done, they advised that what they do know is that the Pax file has to be build in Paxstore with "POS Auto Register" enabled under Communications. 

We are unable to print, evenly split checks, BEFORE being paid. It is only possible to print when splitting a check manually, and dividing each separate item on the check. This is very very time consuming.

An example of a guest interaction. 4 people say .. "Can you split this check evenly". So we can not do it and print. We can only present the check as it is and pick up 4 credit cards or cash.
If we have them on their own seat it is ok and we can print. The problem again is with an even split. Thats in half, thirds whatever. Our old system from 1932 was able to do this. Please please help
