The patent point out that networked portable devices which employ infra-red or radio-frequency communication have limitations. Radio devices use a lot of power, and are prone to interference from others operating on similar frequencies. There are also fears that people might be able to hack into them or, at the least, listen in. Infra-red communication suffers the same problems, but has the additional limitation of requiring a direct line of sight between objects-as anyone who has tried to operate a television remote control with someone else standing between him and the television will know.

Microsoft claims that its approach of "near field intrabody communication"does not suffer from these problems, and provides a secure way to transfer data between devices.

    這個專利指出紅外線及無線電波的網路可攜式通訊設備有他的限制.無線電設備耗費很多電力,而且容易被同樣在附近頻段運作的服務所干擾.另外也有人因此而擔心他們會被駭客攻擊,或至少被竊聽.

    紅外線通訊也有一樣的問題,但他還多一項限制,就是兩個物體間必須保持可視的直線距離,就像電視遙控器和電視中間若有人的話,就無法傳遞信號了

    微軟宣稱"近場體內通訊"就沒有這樣的問題,而且他還提供了一個安全的方法來在設備間傳輸資料
