I have some clarification questions regarding the “transaction_intermediary” variable listed in the spending data those questions are:
What does the value of “No intermediation” represents? Does it mean the transaction was completed by paying cash, or does it mean that the intermediation information is not available for those transactions?
The online description states: “The number of transactions at this POI is based on the intermediary through which the transaction was made, if any. Transactions can have multiple intermediaries, in which case the number of transactions will be incremented for each intermediary.” Can you please clarify what exactly this variable measures? For some intermediaries, it is pretty clear what it measures. For example, a transaction intermediated by GrubHub was probably placed through the GrubHub app. However, what does it mean to have a transaction intermediated by Visa? Does that mean the consumer used a Visa credit card? Similarly, what does it mean to have a transaction intermediated by Square? Does that mean the store has a Square POS system?
For the transactions having multiple intermediaries, for example, if the transaction was completed through DoorDash at KFC, and paid with a visa credit card(or Apple Pay) within the DoorDash app, under such case, is the transaction counted both under the DoorDash and Visa(Apple Pay) category when counting the number of transactions?
Thank you for the help!
