Interaction of transactions

How should transactions be designed to take advantage of the change in interface?

CONSIDERATIONS FROM BRIEF:
1. The speed of transaction with the ability to simply touch a payment terminal with a mobile phone.
2. The ability to enter a pin number on one’s own device instead of using a terminal. With the ability to change the security level to suit individual requirements this should allow payment interactions to work more efficiently and to be more secure.
3. The ability to process more customers.

What kinds of interfaces would be ideal for transactions and how might they be implemented on the mobile phone? How might we add valuable new interactions, services or information into the transaction process that makes it more useful than simple payments? Might there be other significant downsides as we expose our phone for every transaction? What about keeping a phone concealed for safety or the perceived risk of disclosing personal data by touching un-trusted objects?

In collaboration with Alice Andreoli, I’ve studyed these emerging interactions, and looked upon how they can be implemented or designed around daily infrastructures, as we both want to look into how to design specific services with ideal use of “payment objects”

We want to look closer into relations between control/knowledge, visibility and trust.
We think the success of NFC depends on the usability of mobile payments and ticketing and wether or not the design of this experience is good /plesant /trustworthy.
What will provide the new payment history? How will we trust future systems? How might we as users act upon new opportunities in interactions of transactions?

I feel we need to find out more regarding trust and technological innovation and adoption. I want to look more into the intersections of technology, spaces and access / payment-culture.
