A digital business card is the modern way to exchange contact information. Also known as virtual and electronic business card, digital business cards are highly customizable, interactive, simple to share, and cost-effective alternatives to physical cards.

Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devises over a distance of 4cm or 1.57 inches or less.

It the same technology that is used for “Tap-&-Go” transactions and central to every contactless mobile action is a little microchip and a radio antenna. This is near field communication (NFC).

An NFC business cards enable you to share your contact information with a single tap of your business card on a new friends smartphone.

NFC business cards have an embedded microchip and a radio antenna to allow them to communicate with other NFC devises.

YES, digital business cards are absolutely worth it. Beside being eco friendly and the “last business card you will need” this virtual networking tool ensures that people you meet have your contact in their mobile from the time you meet.

Your contact information, photo and business logo can be updated (via your profile) and even on the move.

NO, the cards use Near Field Communications (NFC) this is the same as your ‘Paywave’ bank card.  There is a thin wire antenna and a chip embedded in the card.  When it is near an NFC device, it is powered by the radio waves.

YES, the cards are sealed during manufacture (weather it is bamboo or carbonfibe/PVC).  But they can be damanged by bending!

Contactless cards use Near Field Communication (NFC) to enable transactions, a subset of Radio Frequency Identification (RFID). Compared to RFID, NFC works for smaller distances in the range of ten centimeters, while RFID technology can transmit data up to 100 meters.

Different manufacturers put the antenna (sensor) in different places.

Android, is usually on the back (but location can vary) see here NFC Location 

Apple, put thiers on the front at the top.
