put the start and end dates in the url and then sign the url Then encode this as a barcode
This will probably result in a string that is too long for a 1D barcode but would be ok for a qr code

Generate QR code which expire after specific date
I am using PHP and creating a project where I need the barcode, I want to make it available at a specific time. I want to add a date picker where I add the starting date and ending date, when the due date is passed, the barcode will not be able to read again. (expire).
I already generated the code but I want to make it expirable, any idea how can I do this. If there is any lib, please suggest it to me.
