Companies such as Ticketcorner that supply admission tickets to entertainment and sporting events increasingly rely on Internet-based ordering systems. Ticketcorner has developed its own automated ticket checking system in conjunction with OPAL Associates. This is based around Dolphin® 9500 mobile computers from Honeywell. The Dolphins recognise all types of tickets—from classical paper tickets through to print@home tickets. They also support the latest RFID (radio frequency identification) technology.
