I Think it would be nice to have the actual Ticket/registration confirmation number
generated for every registrant of a group seperately
beeing able to create the barcode from variables e.g.
[EventID][Confirmationnumber]["Customfield"] could be helpfull
for entrance needs..
also a "Ticket as PDF-mail" funktion would be nice
it should, if you check it, instead of sending a plain HTML mail...
generate a PDF file from This confirmation-mail
(with barcode, infos, logos etc.), attache it to an e mail with basic Text
"Hello, please See attachent fo your ticket..."
wich is then be send out to the Registrants mail address -
but the PDF schould not be saved!or then be deleted after sending..
..if Registrant needs to get a 2nd mail - it is generated again
( Resend Mail Button on "Records" Page)
this would make the server environment safer as well, as you would not reveal a path into the system (by sending a barcodelink in the HTML mail) to the barcodefolder, wich then could be guarded as only accessible via Localhost.
(I Know It is barely impossible to get a valid barcode by typing a path in radomly
if you have a propper prefix that is changed frequently -
but as I sayd you would reveal your systems Idendity)
plus then , depending on the PDF library´s capability, Registration basded
watermarks ( With Registrant and Eventinfo ) could be generated and added to give the tickets a bit more security
