Cardful is an app that is part of the Evernote series. Meaning all the information on it would be also available on all devices and computers sharing the same account.
Very much like the app CardMunch which I had a post on in the past on this blog, Cardful has very much the same features. With the added benefit of having access to the business card you have collected on all your devices.
Another feature that I really enjoy is the Tag List. You can set up a list of tag words you can later assign to the business card. This feature is perfect for creating your contact database. At the same time as you receive a business card and take a picture of it with your phone. You can ask the person handing you the card what kind of real estate investor they are. You can then quickly add if they are wholesalers, hard money lenders, if they concentrate on Buy/Rent/Hold, lease option, commercial properties. Or do they go for single family homes, multi unit. Are they Rich Dad Education students or are they part of REIN.
The one draw back is that this app does not link with LinkedIn.
If you have used CardMunch and liked it, you may want to also try this one and see which better suits your need. At this time, I'm not sure I have a preference, except maybe that since Cardful is available to all device and computers, loosing your phone or having a malfunction does not mean you have lots all your contacts.
