No.
Payers (your friends) DO NOT have to sign-up to PayUp Jack; they just need a valid email address.
We’ve made it easy for Social Organizers to get THEIR money! Only the Social Organizer needs to sign-up and be a member. The Social Organizer just needs the email address of all the friends (the Payers).
Your friends will receive a secure email with a link to make payment. The Payers select the link and make the payment with a Visa Card or VISA Debit Card, or a Debit card on the “Plus” Network (see the back of the card).
It’s all done with their email address!
