Do customers pay with cash or credit cards?
We advertise that some vendors may be “cash only”, but most opt to accept credit cards. Many vendors use credit card “readers” (ie: Square or Paypal) --with an Ipad or smart phone.
If you choose to accept credit cards, you may want to post a sign in your booth stating “Credit Cards Accepted”. Also note, an ATM (w/ bank fees) will be available inside/outside the event hall.
