I would be interested to do these apps for you using NFC I read your requirement and have a fair idea on what you are looking for -something I did so many times.
I started with RFID and NFC way back in 2007 with Nokia NFC API, gradually adapted to new platforms. For the past 12 months, we had been delivering apps for Android and Blackberry using NFC API's from respective platforms.
I use Nexus S as an NFC Reader/Phone on Mobile applications and Omnikey or ACR122 series RFID readers for desktop applications using C++.
I am a developer with an experience of 12 yrs in coding, 5 years as Project Lead on various sizes.I have done work on iOS, Bada, Blackberry and Windows platforms.
I have the needed NFC NXP tags, Readers for the development and the IDE for coding. I use Nexus S with Android 4.01
I like to know a few things before I give you a quote.
1) Do you have special requirements on the UI or you have a UI designer who does the creatives ?
2) Any deadlines or milestones on the completion of the work ?
3) Does any of the apps need a back end service -do you have one or is it in the scope of this project ?
I am sending you a slide deck of screenshots from my previous work and also feedbacks received during these development efforts.
Please do get back to me on further questions.
Best Regards
