Q&A with Transactions app developers: Kyle Richter and Ian Baird

I recently had the opportunity to sit down (virtually) and have a chat with Kyle Richter and Ian Baird, two iPhone developers who have come up with the game-changing Handshake app for contact sharing on the iPhone (TUAW review), then released the credit card and payments app Transactions (TUAW review) which can transform any iPhone or iPod touch into a basic point-of-sale device. We talked about how they came up with the idea of their Transactions application, and they shared their experience of developing for the iPhone.

Cory: What was your vision behind creating Transactions, and why did you pursue this idea and turn it into an iPhone application?

Kyle: When working with a platform that is as new as the iPhone the goal is to try and find niches that haven't yet be filled or not properly filled. While I was out jogging with Ian one evening it hit me that a lot of businesses have a need to accept credit cards anywhere. It felt like a perfect solution for the iPhone so we started to research the feasibility.

Ian: One of the driving influences for us has been to take advantage of the "democratizing force" of the platform. We have Authorize.net for the higher end, more professional users who will use this app on a day to day basis. We also felt we needed to make this application accessible to the farmer who's selling his or her produce at the farmer's market. Or the craftsperson selling his or her wares at a trade show. That was the motivation for including the Paypal option. It doesn't require a merchant account. That's a *big deal*.

First Look: Handshake for iPhone



How many times have you been away from your computer and wanted to give someone your contact information? With a new app called Handshake [iTunes Link], you can send another iPhone (or iPod touch) user any contact information stored on your iPhone. The application works by using Core Location coupled with other technologies to send address book cards over the air.

When you first launch Handshake, it will attempt to find your address book card; if it can't, it will ask you to specify a card. Handshake will then connect to its servers, and you will be able to send either your card, a contact's card, or a picture -- just by tapping on one of the main three buttons. You can also change your default card by tapping the wrench in the top-right corner of the application and choosing the blue arrow under "My Card."

This is a very simple application, with a very simple idea, that just works. The application will send data over WiFi, 3G, and EDGE connections. Since the application uses Apple's Core Location framework, it relies on GPS, cell triangulation, or WiFi positioning. The lack of GPS on the iPod touch makes the app less reliable than the iPhone, but a new feature in version 1.1 hopes to fix this by allowing users to search for others who are sharing cards. Version 1.1 will also give users the ability to send industry-standard vCards through email to other people, regardless of whether they're using an iPhone or not.

Handshake is currently at version 1.0.1, and can be downloaded from the iTunes Store in two flavors: free or paid. The paid version removes the ads. Version 1.1 should be out sometime this week. You can look at our gallery of screenshots to see the additions to version 1.1.





Thanks to Kyle Richter and Ian Baird for the information, and their help!

Tip of the Day

To get an instant map to any address, just go to your Address Book and right click on the address field of any one of your contacts and select "Map Of." The address will then be revealed in Google Maps on Safari. You can do the same if a data detector determines there is an address in an e-mail in Mail.
