求翻译：传统一卡通采用M1（Mifare one）卡，随着应用领域的扩展和深入，M1卡难以满足更高的安全性和更复杂的多应用需求，尤其是在M1卡的安全被攻破的情况下，对IC卡的安全性显得尤为重要和紧迫。传统的方式需要携带卡片，不方便且容易忘记携带，一张卡只限在一家单位使用，是一张“盲卡”，用户看不到卡内信息，也无法对卡进行操作。因此，发展非接触CPU卡技术正成为非接触IC卡技术更新换代的重要趋势。是什么意思？

Traditional card M1 (Mifare one) card, with the expansion of application areas and in-depth, M1 cards difficult to meet a higher level of security, and more complex applications, particularly in the case of M1 card security is compromised, to IC card security is particularly important and urgent. Traditional way to carry a card, not convenient and easy to forget to carry, a card is restricted to a unit, is a "blind card", the user cannot see the card information, or operations on the card. Therefore, the development of contactless CPU card technology is becoming an important non-contact IC card technology replacement trend.
