It can be a number of reasons why you are getting a declined message from your card!
Here's a few reasons it might not be working:
I'm using a visa/mastercard debit
Certain organizers are unable to accept visa/mastercard debit. During checkout, you will see this message 
. That means you will have to use another type of credit card!
I'm using a prepaid credit card
Please ensure the credit card has a greater amount on the card than the total amount you are trying to charge to it!
You will also have to register the card online before you are able to use it. Follow the instructions on the card to register online!
It's saying its not going through
Your bank may be blocking this purchase if its not a normal purchase for you. Please double check with you bank whether they can allow this purchase or not. If you are still having troubles after doing this, send us an email at support@showpass.com and we can look into what is going on!
It says my expiry date is wrong
Please check that you have entered in your credit card number correctly!
