That is our issue also, we have one lane in and there are over 200 parent cars waiting for pick up bakcing up traffic down the street blocking buses from entering and exiting. The plan is to give each student a barcode for the car, the admin will scan each barcode using an app updated
Scan to Google Sheets which then populates to a view only google sheet that is shared with all teachers. As students pop up on the spreadsheet, they will be sent down to the pick up area. We have two pick up areas at this time and each can hold 20 cars in que so the plan is to send them in groups of 20, we can scan cars ahead of time and get students lined up much quicker. It isn't ideal, still some things to work out. Hope to implement this next week.
We used an array formula to create a url in the source sheet that will merge to autocrat to create an QR code that is scanned by the app. A new spreadsheet is what will be shared with the pick up groups.
Here is the array formula we used:
={"combined name";arrayformula(A2:A&" "&B2:B)}
To merge to autocrat I used an image field type and mapped it to the USE URL column. Works like a charm!!
