Abstract: A stand-in payment and transaction facilitator system is provided. A merchant registers their details with a transaction facilitator and is assigned a merchant identifier. When a mobile user transacts with the merchant, the merchant identifier is communicated to the user's mobile device. At the payment step, the transaction facilitator uses the merchant's details referenced by their identifier to complete the payment portion of the transaction using any non-cash payment mechanism or service of the users choosing. The transaction facilitator offers for-purchase items from the merchants. The merchants use preferred payment providers. Communication devices are used to select for-purchase items from the transaction facilitator. The transaction facilitator communicates payment information received from the communication device to a financial transaction network for payment in the transaction to purchase the for-purchase item.
