Why do I need a credit card on file to list tickets for sale and why do I see a pending authorization on my credit card?

We run an authorization on the credit card on file to make sure every seller has a valid card when listing tickets for sale. In the unfortunate event that there was an issue with an order such as tickets not being delivered or were invalid for entry, a fee can be processed to secure replacement tickets for buyers or compensation in the form of TickPick credit.
