Without question, the way that e-tickets are being defined right now (electronic tickets that can be done via sending over a cellular phone) to replace the usual ticketing mediums we have traditionally heard of is something that may take some time to iron out. While it is quite commendable to address the usual ticketing procedures that events make use of for control, using technological devices such as cellular phones seems to be far off from happening.

For one thing, people will always find a way. Loopholes in addressing these methods are certainly something that any geek would try to overcome. Text-messaging is a great recourse but unless you develop a proper medium to avoid fraudulent acts such as fabricating messages to look like authentic e-tickets, it is doubtful to be used soon.

Paperless tickets are an eco-friendly, new version of the electronic ticket. Soon, tickets will be delivered via cell phones. Several problems regarding this new technology are still being smoothed out.

A panel of executives addressed some of the merits and disadvantages of using hard vs. paperless tickets. While paperless tickets would definitely be the environmentally progressive way to go, hard tickets will never actually disappear forever. Some people without computers and cell phones or those who want a copy of their tickets as a souvenir ensure the continued use of hard tickets for the future.
