For Hack Cambridge Monzo is exposing an API to allow you to send us receipt information for your transactions. This information will be displayed in the app in the details screen for that transaction. The challenge is to figure out a way of automatically getting useful receipts into Monzo! Some ideas: 1. Parse email receipts for purchases 2. Use OCR on images of paper receipts 3. Use an api of another company - Uber, Deliveroo, TFL? Talk to the Monzo mentors for help getting started!

TransferWise Hack

Borderless Account, also known as Balances, is our latest offering that allows our customers to receive and hold money in over 40 currencies with zero fees. It isn't just a traditional multi-currency account where one could only load money in a specific currency, it rather offers local bank account details for receiving USD, EUR, GBP, AUD and NZD. This allows our customers to pay (or be paid) in a specific currency immediately, without any foreign exchange conversion, as if they actually had an account in the country operating with the said currency. Moreover, our customers could also use their TransferWise Debit Card globally, without ever having to worry about converting currencies - we automatically use their balance from the currency that offers them best conversion rates to fund their spending! Build a solution that frees our customers from having to manually perform payments of repetitive nature from their Borderless Accounts. Imagine you are a freelance software engineer who takes up projects from clients globally, uses borderless account to get paid, and has direct debits set up with a local bank for paying all the bills. Or imagine you are an expat who needs to send a portion of their salary to their family in their home country. Or perhaps you are a traveller who is planning a trip abroad and wants to hedge funds systematically to prevent against dramatic fluctuation of exchange rates. Wouldn't it be awesome if TransferWise does all the work for you to perform smart conversions using your preferences?

We'd like you to come up with use cases that you'd like to solve, determine what user preferences would be, and build a solution that our users would love to use - we'd love to leave this problem a bit open for you to have room for innovation, and make your solution to be as smart as you want to make it.

TransferWise is a customer-centric company, and we always place our Customers at the core of all our decisions. We love to step into their shoes and think about their use cases, feedback, and experience to bring improvements to our systems and introduce new features. Your solution would be evaluated along the same lines:

  • Impact of your solution
    • • Capabilities
    • • Effectiveness
    • • Value to our customers
  • Ease of Use
  • Scalability

Integrate the Avast Secure Browser and CCleaner products to improve user privacy, prevent website tracking & reduce browsing footprints

Companies that rely heavily on advertising revenue are aggressively tracking and commercialising you while you’re browsing, searching, and shopping online.

For our challenge, you’ll explore the full possibilities of what can be done with with an integration between these two hugely popular products. We’ll give you access to custom builds of our CCleaner and Avast Secure Browser applications, so you can: Create an integration between CCleaner and Avast Secure Browser to clean user browsing data and report the results within CCleaner Build a CCleaner browser extension to clean Avast Secure Browser in real time, making use of custom browser APIs Explore new and innovative ways to improve user privacy online through cleaning, including making of use of other available browser features Just remember: reaching simple, elegant solutions can often help solve the most technical and complex challenges. We’ll judge competing teams based on teamwork, quality of the end solution, and creativity. We can’t wait to see what you come up with!

Medical Record Integration

TPP are excited to announce a competition for the Cambridge Hackathon. At TPP, we are revolutionising patient healthcare, both within the NHS and across the world. To do this, our Software Developers are always looking at improvements to our system and working on new ways to give patients more control over their own care. This year we want to give you a chance to test your skills by creating your own revolutionary design for the healthcare industry. TPP will be providing access to dummy patient data from SystmOne, one of the UK’s largest digital healthcare systems. You will be able to integrate with SystmOne, retrieving patient data and booking appointments. Access will be available to demographic data, appointment information, drug history, allergies and medical sensitivities. You will have free range to use this data, perhaps to develop an app or piece of software that could be used to improve patient care. You could create a revolutionary new appointment booking system or a personal healthcare application- the possibilities are endless.
