Just to add a bit of context ahead of the club communication about this...
The test event was only approved today by authorities not leaving much time to organise things. So time is against the club in that respect.
Also the same rules will apply to all test events, in that only paper tickets can be issued and they have to be posted out. This means any tickets need to be ready to post out by end of tomorrow.
With the above in mind, they have to put a process in place that can be implemented quickly as possible.
