I just got done reading about DeviceFidelity (in a MobileCrunch post by Greg Kumparak)  a company that is producing a micro SD card that will allow your phone to act as a credit card using NFC (Near Field Communication) technology.  It’s called In2Pay.  I have spoken about this in the past and even got interviewed for a piece about it in a major news magazine (I can’t find the link right now).  I am a huge advocate and think this is the best inovation in mobile phone accessories since the car charger.  This will finally make it so I can go out and about without my wallet and buy anything I want.  I won’t need to worry about carrying credit cards any longer.  Personally I hope American Express will support this but if not this is enough to make me switch to what ever credit card company does.  Right now it looks like only Visa supports it but I truly hope it will catch on.  I know soooo many normobs (normal mobile users) who would use this let alone the huge number of techy folks.

If the mobile service providers like AT&T and T-Mobile or any of them around the world supported this I think it would cause a large boost in roaming as well from people who will just take their phones with them (when roaming abroad) and of course turn them on so they can use the In2Pay service.

What does this mean for the consumer in general?  Well most current mobile phones around the world use microSD as the standard memory card format.  In2Pay is integrated in a microSD card.  So if you pop an In2Pay microSD card into your phone, install any necessary software you should be ready to charge to your hearts content at any cash register that uses contactless payment.

To say the least I’m very excited.  If by any chance DeviceFidelity reads this then PLEASE send me one of these microSD cards.  If you really care then I also have a lot of thoughts on this and would really like to share them with you.

Are you interested in this kind of thing?  Are you willing to put your credit card in your phone?  Is security a concern for you?  Please comment below to let me know?
