The invention relates to a design and application method for a 4D
digital business card, which comprises the following steps that 1) firstly, a
business card generation
client side logs in a
digital business card storage
server, registers an account, establishes a personal file, and obtains business identity (BID) number information of the
business card generation
client side; 2) the
business card generation
client side automatically generates the
digital business card and a two-dimensional code business card pattern according to personal business card
public information input by a user, the BID number and a digital business card acquisition
password; 3) the business card generation
client side logs in the digital business card storage
server again, and the digital business card generated in the step 2) is uploaded; 4) after the two-dimensional code business card pattern generated in the step 2) is stored, the business card generation
client side prints the two-dimensional code business card pattern on the papery business card of the business card generation
client side; 5) the business card generation client side notifies a business card reading client side of BM (BID+MM) encoding in various
modes; and 6) the business card reading client side downloads the corresponding digital business card by the BM encoding. Compared with the prior art, the design and application method for the 4D digital business card, which is disclosed by the invention, has the advantages of high information transmissibility, high information
accommodation rate, high updating speed and the like.
