The outdoor sculpture show was held in Colorado in August. I began the following preparation about a month in advance.
1. Credit Card Process
A Colorado resident said Verizon would cover the area the best. I purchased an used smartphone and decided to get a one-month prepaid coverage a week prior to my departure. Two people recommended Square to process credit card transactions. I registered with the company, received a reader, and practiced processing with my own credit card.
*** Swiping a credit card through a Square reader can be tricky. I strongly recommend you practice with it. ***
2. Special Event Sales Tax License
I took care of the necessary paperwork in advance. Neither the city nor the state required the special event participant to carry the sales tax license with him/her at the time of the event, as long as he/she had a copy of the application forms.
*** The event organizer gave us wrong information about the sales taxes, and it was confusing. I found it was the best to contact the appropriate revenue department for questions. ***
