Billing Credit Card Terminal

[spartadata]

Hi,

I hope it is ok to post about our own creations, projects and efforts. I hope to get some feedback and open dialog with others. 

It has been a little over a month now that my initial iphone app has been released. Apple has showcased it on both itunes main page and on their latest TV commercial for iphone apps. I feel this has all been a stroke of luck... 

So I wanted to share my work here:

The app is called: Billing Credit Card Terminal

It runs on all iPhones and iPod Touch and works on both WiFi and Carrier connectivity 2g, 3g...

The app uses the Authorize.net API to post securely via HTTPS and does not store any card holder data. There are already a hand full of similar apps however I made it a personal challenge not to copy any of them as such Billing has its own unique interface and workflow. The key features includes a touch based signature capture that allows customers to sign with their finger right onto the iphone or ipod touch. Additionally the app supports full merchant tip functionality and includes a robust receipt feature which includes the signature and transaction details. There is a lot more to the app then these features I just described however you might enjoy seeing it in action via YouTube. I have links on my site.

I am currently on queue to become certified as a solution provider on Authorize.net and hope this progresses soon.

Looking forward to that.

Hi Michael,

I'm currently stuck on iPhone authentication and wonder if you have come across similar issues.

The main issue is I keep getting a response "(13) The merchant login ID or password is invalid or the account is inactive".

My delegate methods do the following:

connectionShouldUseCredentialStorage:

- return NO;

canAuthenticateAgainstProtectionSpace:

- return YES;

didReceiveAuthenticationChallenge:

- creates NSURLCredential with account (not x_login) and password, then calls selector useCredential:forAuthenticationChallenge: on the sender property of the passed in challenge object

I feel like I'm doing those things correctly. The only thing I might be missing is using a credential with a certificate instead of just username/password. Any ideas?

The problem here is that authorize was a little late to the party to release their iPhone application where everybody else has had mobile credit card processing and it might have hhurt them as some included me defected over to paypal for one of my sports sites however, I may give it a shot and check it out but whats your honest feedback on it?
