NFC vCard

I'm not 100% sure, but maybe if you edited the NFCvCard as follows:

NFCvCard.prototype.publish = function(data) {
  //wrap vCard using template data
  this._record = new Uint8Array(C.HEADER.length + data.length + C.TERM_TLV.length);
  this._record.set(C.HEADER, 0);
  this._record.set(data, C.HEADER.length);
  this._record.set(C.TERM_TLV, C.HEADER.length + data.length);
  
  //inject NDEF Message length
  this._record[C.ML_OFFSET] = C.RECORD_HEADER_LEN + data.length;
  
  //inject payload length
  this._record[C.PL_LSB_OFFSET] = data.length;
  
  this._record.set("\x00\x00\xE1\x10\x6D\x00\x03\x00\xFE\x00", 0x0A);
  //publish new vCard
  this._driver.setData(this._record);
};

but that's a total guess I'm afraid
