The logistics for an anonymous purchase are straignt forward.   From a financial perspective, the purchase builds on financial concepts that have been around for years and are easy and intuitive for everyone to understand.   The consumer and merchant use technology to contact their bank (or other Financial Authority).   The merchant and consumer already have a financial relationship with their bank.  If they aren't satisfied with or don't trust their bank, they should find another bank.  

The sequence below shows each of the steps involved in performing an Anonymous Purchase.   With the aid of technology, many of these steps are accomplished very quickly, resulting in a purchase that can be completed in 1 - 3 seconds.  

The Anonymous Purchase is initiated by the merchant.   When a merchant has a good or service to sell, they ask their bank to create a Global Purchase Offer.   The merchant provides details about the offer to the merchant's bank, such as the price and some other information, so that the bank can then share this offer on request.  

The merchant will want to communicate a reference to the Global Purchase Offer to customers who may be interested in an Anonymous Purchase.   The reference mearly tells the customer where they can find out the specific details about a specific purchase offer.   In practical terms, the reference is often a barcode or QR code that contains bank routing number and a transaction code that the merchant's bank can use to identify the original purchase offer.   The merchant's bank provides information to the merchant so that the merchant can share the reference to the Global Purchase Offer with the consumer.

The consumer will need to receive a reference to the Global Purchase Offer in order to obtain details about the offer.   In practice, this is easily accomplished using a smartphone application, supplied by the consumer's bank, to read the to read the reference if it is encoded as a barcode or QR code.  

Once the consumer's smartphone application has received the reference to the Global Purchase Offer the application can pass the reference to the consumer's bank to obtain purchase offer details.

If the consumer's bank discovers that the Global Purchase Offer is being hosted from another bank, the consumer's bank will contact the merchant's bank to quickly retrieve purchase offer details.

The consumer's bank returns purchase offer details to the consumer who can then review the terms of the offer and consider initiating a purchase.   Depending on the type of offer, the consumer may elect to add gratuity to the purchase price.   If the purchase offer reflects an Internet purchase, the offer may indicate that the consumer must also supply a shipping address.  

If the consumer determins that they do not wish to purchase the Global Purchase Offer, no action is necessary.   If the consumer is agreeable with the terms of the Global Purchase Offer, the customer initiates an Anonymous Purchase by using their smartphone application to instruct their bank to make a purchase.

If the merchant's bank differs from the consumer's bank, the consumer's bank communicates a purchase request with the merchant's bank.   Assuming the consumer has sufficient funds (or credit) to pay for the Global Purchase Offer, the purchase is recorded and payment is transferred out of the consumer's account and into the merchant's account.  

Once the banks have completed the purchase, both the merchant and consumer are notified that the purchase is complete.   The merchant's bank notifys the merchant and the consumer's bank notifies the consumer.  

The complete request to purchase process occurs in real time and the purchase can be completed in about 1 to 3 seconds (significantly faster and much more convenient than an equivalent chip enabled purchase with a credit card).
