In order to be able to issue tickets (paper or electronic - it doesn't matter in this case) you need to go through a very extensive application - about 20 pages long if I remember correctly, get bonding, have an extensive background check, etc. Probably not worth it unless you would be doing higher volume ticketing than even a few tickets a month for yourself. There is a cost to maintaining the bond and an annual fee you must pay, not to mention needing to report your ticket sales (or lack thereof) every week.
