一种具有单面刷卡功能的电子卡片容器的研制

Development of an Electronic Card Container with Single-Side Card Brushing Function

摘要: 学生时代，公交卡与饭卡(或校园卡)是学生经常用到的两卡，两卡往往放在一起。为了解决现阶段学生用卡不方便的问题，拟研制一种新型卡片容器，解决两卡不能同时叠放使用的难题。为了达到卡片防碰撞，市场上对于一些专用的读卡器通过卡片的时或位来进行判断，但这对于读卡器的更换成本较高，且对于如公交卡这类广泛使用的卡也有明显的数量限制，对此提出了利用一种具有单面刷卡功能的容器来解决这一暂时未得到合理解决的问题。初步产品是一款皮质双面卡套，中间夹层置有我们经过多次试验得出的定向屏蔽材料；使用时，卡套的两面分别对应两张IC卡，通过翻转可以得到两种不同的用途，解决了传统钱包、卡套中多张IC卡无法同时使用的问题，避免了在人群前反复翻找的尴尬。技术方面，本课题采用被动屏蔽的方式，无需电源、成本低廉、效果可靠，有效地为生活带来了便利。

Abstract: In student days, bus card and meal card (or campus card) are two cards often used by students, and they are often put together. In order to solve the problem of inconvenience in using cards for students at this stage, a new type of card container will be developed to solve the problem that two cards can not be overlapped at the same time. In order to prevent card collision, some special reader judges the time or bit of the card in the market, but this has a high replacement cost for the reader, and there are obvious limitations on the number of cards widely used, such as bus cards. To solve this problem, a container with one-sided card brushing function is proposed to solve this unreasonable problem. The preliminary product is a leather double-sided jacket with directional shielding material in the middle layer. When used, the two sides of the jacket correspond to two IC cards respectively. By flipping, two different uses can be obtained, which solves the problem that multiple IC cards in the traditional wallet and jacket can not be used at the same time and avoids the embarrassment of repeatedly searching in front of the crowd. In terms of technology, the pas-sive shielding method is adopted in this subject, which is power-free, low-cost and reliable, and effectively brings convenience to life.
