I do not believe that it will work ANYWHERE contact payments are presently accepted. Note this text from the Revel POS press release about Apple Pay:
" There are currently six companies that work with Apple Pay, including:
Authorize.Net
Chase Paymentech
CyberSource
First Data
TSYS
Stripe
To begin utilizing Apple Pay, Revel clients are required to create an account with Chase. This will work independently from the customer's merchant account unless he or she wishes to use Chase as their merchant account as well."
Not all retailers are going to have done this, or are even going to be willing to do so. I do system work for some retailers who I can say with out a doubt are not going to be willing to bring in another provider or switch their accounts to say a Chase.
