So the teacher has to scan a physical qr code with their phone, and you need to scan them all at once? Maybe don't use qr codes? Rfid perhaps?

How scanning Multiple QrCodes at one time ?
I have students module every student has qrcode my snario in app is In order to track the movement of the student on the bus to and from the school, the QR code is scanned by the supervisor, and it is difficult for the supervisor to scan one student after another. What is the best way to scan all the students at once?

@ibtdi But that’s the point of QR codes? They’re scanned. You can’t just magically scan multiple QR codes in one go.

I think your scenario is something like this
- Student1's code is scanned.
- System does something
- System confirms the scan
- Student2's code is scanned
- System does something
- System confirms the scan
- And so on for each student.
You want it to behave something like this.
- Student1 is scanned
- Student2 is scanned
- Student3 is scanned
- Last student is scanned.
- System does something
- System confirms all scans.
If so you need to create some sort of array where you store each scan. Preferably in local storage in case something goes wrong. Then when every one is scanned you submit all of the values scanned to your backend.

@Tray2 I wouldn’t bother. They posted this on Laracasts and haven’t bothered to response to the replies there either.

@Tray2 I want till you the supervisor version app is only end-user so he has permissions to update students data

@ibtdi In proper English please. I have no clue what you mean.
Level 1
@Tray2 I mean the supervisor alone who has the authority to update the students' data and not the students themselves

@ibtdi Who said anything about students updating? The person scanning the cards sends the request when all scans are done. What you do with it after is up to you.
