How it works right now
In my introductory posts about this project, I noted my frustration with the flow through conducting a credit/debit transaction. The image below formalizes the steps I drafted earlier into a flow chart. If you’ve not encountered flow charts before, the rectangles represent process and the diamond shapes represent decisions.
I want to call out the “Enter Payment” box in the lower right. One of the specific difficulties of using the app is entering payment details. The payment screen requires:
- Credit card number
- Expiration date
- Buyer’s name
- Buyer’s zip code
- Buyer’s email address
These are standard payment inputs. The complication here is that it requires handing the phone back and forth between seller and buyer as they complete fields. That interaction forces both parties to be vulnerable in handling private information; the seller because they hand their phone over and the buyer because they hand their card over.
*Note: An important UX principal is to ask questions about why we are asking for our users’ information and what are we going to do with it? An email address is required to complete the transaction. I would question how else the email will be used.
