13 teams participated in our Frictionless Urban Payments challenge, where the idea was to make paying in the future easier, even unnoticeable. We will now present our winners!
1) CUP-CUP-GO – Take your cup, fill it in and go!
“In a busy world, there is no time for standing in line to wait for your morning coffee, or for your beer in the bar. With cup-cup-go you can just fill your cup and go!”
This team won both our challenge and the whole Data Economics -track with their smart coffee cups. They built a functioning prototype of a coffee maker and a web-app, where the transactions can be seen. They used Raspberry Pi, RFID tags, IoT-concept and Amazon cloud services for this solution.
The idea is that the payments are conducted automatically through the RFID tags in the cups. Users can order tags and attach them to their favorite cups, or just grab tags from the tag-dispenser next to the machine.
What we really appreciated in this solution was its entirety. Even though the team was put together in Junction, they worked together seamlessly. The whole package from design to functionality was built in a detailed fashion. Also, their demo was superb. You can check it from Junction’s stream (2:20:18-).
2) POP IN – Just Pop In
“Do you like queuing to validate your ticket when you get on the train? Do you like having to look for your HSL card when you don’t know where it is? Neither do we.”
Pop In was a team of two, and they amazed us with their solution for the public transport. They used Bluetooth for detecting people’s phones, and the system then automatically validated the ticket. A Raspberry Pi checks for the presence of the phone on-board, and a Node.js application on the RPi retrieves the latest data automatically via WebSockets from the HSL API.
This team really understood the customers’ problems: The validation of tickets (sometimes you just forget, right?) and the issues with knowing what kind of ticket is needed (do you need a regional ticket or not?). From the HSL’s side, the solution provided more accurate statistics.
“Simplicity and better user experience for both ends.”
3) CHECK-OUT – Checking out every item you buy? Paying with cash or phone? What? Is that 2010?
The third place went to a team of three. They built a prototype shopping cart with integrated RFID sensors that will read the products, a fingerprint sensor which recognizes users and a screen to interact with the user.
The system stores the objects placed in the basket and calculates their total, thus eliminating the checkout process at a cashier at the end of the purchase.
When the user has finished choosing the products and is headed to the exit, he/she will be automatically charged on his/her associated card. This solution really improves the user experience of the buying process.
So, here was our TOP 3. However, all the solutions we saw were amazing. We’ll surely discuss about those later on here in the blog.
