Business Card Two-dimensional code generation example

Description: This instance is an instance of generating a two-dimensional code card

1. Need Qrcode_swetake.jar

2. The next step is to introduce the jar package into the project so that the two-dimensional code can be generated

String content= "begin:vcard\n"

+ "version:3.0\n"

+ "FN: Name \ n"

+ "TEL; CELL; VOICE: Phone \ n "

+ "TEL; work; VOICE: Phone \ n "

+ "EMAIL; pref;internet: Mail \ n "

+ "URL: URL \ n"

+ "title: Position \ n"

+ "ROLE: Title \ n"

+ "ADR; work; POSTAL: address; \ n "

+ "ORG: Confidential \ n"

+ "note:qq:\n"

+ "End:vcard";
