A free ticket for one entrance at PLAST 2018 could be required at the receptions by:
TICKET PURCHASE (non-preregistered visitors)
Visitors not preregistered or who lost their ticket had to fill a registration form available in reception and released it to the counters for purchasing the ticket of their interest.
TICKET USE (preregistered visitors)
Preregistered visitors showed their ticket, with Qr Code or Bar Code linked to personal data submitted. The ticket allowed access through turnstiles showing “Fast Lane” logo, reserved to preregistered visitors only.
Improper use or duplication of the ticket had to be avoided: only the first ticket detected at the turnstiles is validated, further copies were voided.
