• Example code to read vcard data from a file and produce a qrcode image

   func main() {
  
      file, err := os.Open("vcard.txt")
      if err != nil {
        log.Fatal(err)
      }
      defer file.Close()
  
      b, err := ioutil.ReadAll(file)
      if err != nil {
        log.Fatal(err)
      }
  
      str := string(b)
      qrFname := "vcard-qr.png"
  
      err = qrcode.WriteFile(str, qrcode.Medium, 256, qrFname)
      if err != nil {
        log.Fatal(err)
      }
  
  }
