Some credit cards may add a foreign fee on your passport photo purchase. In some cases, a $0.04 foreign fee was charged.
Why? The app is based in the USA but our partners are global (which gives us the ability to ship anywhere in the world).
During the checkout process, you have two options to process your payment
1) Credit Cards processed by Stripe
2) Paypal
Haven't heard of Stripe?
Stripe is a credit card processor backed by companies like Visa and American Express (see article). Stripe processes credit card transactions for many large companies like Twitter, Kickstarter, and more.
If you were charged a foreign fee, please let us know which credit card you are using via email us a support @ passportbooth.com.
