Small science mobile phone contact with the bank card will really erase it-wh60a

Small science: mobile phone contact with the bank card will really erase it? The rapid development of the Internet from the Pacific computer network has opened a new door for people to acquire knowledge. However, the network of knowledge of mixed, people will not be careful, will be fooled by rumors. As early as the "hot" mobile base station radiation rumors, leading to a group of collective residents to "rights", strongly asked to remove base stations. And as soon as the discovery of gravitational waves in the near future, there is news that gravitational waves are late, so they are more powerful than electromagnetic waves. At the same time, X treasure also quickly follow up, less than a day, anti gravity radiation suit made out. These rumours might seem ridiculous to us. But most of the elders in the family do not touch this field, so they believe in the news. For us, how to recognize rumors and crack rumors becomes a top priority. Recently, Apple Pay landed in China, successfully set off the boom of mobile phone electronic consumption. At the same time, some people say that mobile phone binding bank card is very good. After successfully tying the card, you don’t have to go out with a bank card. But considering the family elders mostly do not understand mobile phone payment, not to speak of what Apple Pay, cash and bank cards is that they bring to the "wallet", so the question is, will let mobile phone bank card degaussing? Let’s take a look at it. Rely on the bank card magnetic particles store personal information to explain the problem, it is necessary to introduce the working principle of magnetic card and magnetic card. In general, a magnetic card is a card loaded with a magnetic card to store information. From the substrate (plastic) is different, the card can be divided into PET card, PVC card and card three. If it is classified according to the magnetic structure, the magnetic card is divided into two types: magnetic stripe card and full magnetic card. The vast majority of bank cards are magnetic cards, the magnetic stripe on the back of which is evenly distributed with many ferromagnetic particles. You can imagine these small particles into a a small compass. When the directions of these small compasses are random, the magnetic stripe does not exhibit magnetism. But when all the small compasses are in the same direction, they show magnetism. If the surface of the magnetic stripe is divided into many small compartments, and the magnetic properties of each cell are controlled individually, the magnetic stripe has information on it. When the bank card factory, write head card will be issued a changing magnetic field, the magnetic change of each small lattice magnetic field, to write the card number and other information to the magnetic. The bank connects the account you set up in the bank computer system with the card number stored on the bank card. So you can use this bank card to access your account. High temperature and strong magnetic fields, external impact will cause the so-called "degaussing" degaussing, refers to the magnetic particles on the magnetic loss of the magnetic. Generally speaking, degaussing has three kinds of inducements, one is external impact, two is high temperature, three is strong magnetic field. What the elders say is not to put bank cards near the phone, which refers to the interference of the strong magnetic field. Mobile phones do not radiate outward in the form of a strong magnetic field. We all know that the cell phone is working (the radiation of the signal).

小科普:手机接触银行卡真的会消磁吗?   本文来自太平洋电脑网   互联网的高速发展,为人们获取知识打开了一扇新的大门。然而,网络上的知识鱼龙混杂,人们稍不留神,就会被谣言所蛊惑。如早先很“火爆”的手机基站辐射谣言,导致一众住户集体去“维权”,强烈要求撤掉基站。又如近期引力波的发现,立马又有消息表示,引力波发现的晚,所以比电磁波辐射更加厉害。同时,X宝也迅速跟进,不出一天,抗引力波辐射服就做出来了。   这些谣言我们看来可能会觉得比较可笑。但家中的长辈大多数少接触这一领域,所以会对这些消息深信不疑。对于我们而言,如何认清谣言,破解谣言,就成了当务之急。   近期,Apple Pay登陆中国,成功掀起了手机电子消费的热潮。于此同时,又有部分人表示,手机绑定银行卡非常好。成功绑卡之后,就不用带银行卡出门了。但考虑到家中长辈们大多不懂手机支付,更不要说什么Apple Pay了,现金和银行卡才是他们带上街的“钱包”,那么问题来了,手机会让银行卡消磁吗?下面一起来看看。   银行卡依靠磁性小颗粒存储个人信息   要想解释这个问题,就有必要先介绍一下磁卡以及磁卡的工作原理。一般来说,磁卡就是卡片装的,利用“磁”来存储信息的卡片。从基材(塑料板)的不同,磁卡可以分为PET卡、PVC卡以及纸卡三种。如果根据磁性结构来分类,磁卡则分为磁条卡与全磁卡两种。   绝大多数的银行卡都是磁卡,其背面的磁条上均匀分布着许多铁磁性物质小颗粒。可以把这些小颗粒想象成一根一根的小指南针。当这些小指南针的方向杂乱无章的时候,磁条不表现出磁性。但是当所有小指南针的方向全都一致的时候,就会表现出磁性。如果将磁条的表面分成许多个小格,单独控制每一格的磁性,这个磁条上就带有了信息。在银行卡出厂的时候,写卡器的磁头会发出变化的磁场,改变磁条上各个小格的磁场,从而向磁条上写入了卡号等信息。银行则把你在银行计算机系统中建立的账户与银行卡上存储的卡号联系起来。这样你就能使用这张银行卡访问自己的账户了。   高温、强磁场影响、外力撞击才会造成“消磁”   而所谓的消磁,指的就是磁卡上的磁性颗粒失去本该有的磁性。一般来说,消磁有三种诱因,一是外力撞击,二是高温,三是强磁场。而长辈们所说的不要将银行卡放在手机附近,指的就是强磁场的干扰。   手机工作时不以强磁场的形式向外辐射   我们都知道,手机在工作时(信号的辐射)主要依靠的是电磁波。然而,在手机工作的频率区域内,其主要能量形式是电场而非磁场,这就导致磁场强度不足以使银行卡消磁。更重要的是,目前的磁卡都有一定的抗磁能力。所以没有必要过分担心银行卡被手机消磁。   又有网友表示疑惑,尽管手机工作产生的磁场能量很小,但手机中其他部件在工作时不产生磁场吗?其实,手机中的确还有其他零件可以直接产生磁场,如震动马达,扬声器等等。然而,这些零件产生的磁场强度同样非常低,不用担心银行卡靠近手机导致的消磁问题。   芯片卡正逐渐取代磁卡   这几年,磁条银行卡正逐渐被芯片银行卡所取代。在我们的生活中,无论是公交卡,饭卡还是身份证等,这些卡片大多都是芯片卡。其信息全部存储于特定的芯片之中,依靠射频技术进行识别,完全不用担心消磁的问题。   由此可知,所谓的手机会使银行卡消磁现象是无需担心的。但在生活中,小编还是建议您将银行卡远离手机。毕竟我们并不能保证所有的手机质量优秀,电磁辐射都能保证在一个合理的水平上。而且,各地的银行卡质量可能不同。若是将手机和银行卡放在一起发生摩擦,则有很大的可能使银行卡造成机械性的损伤。   生活中总是充斥着各种各样的谣言,能正确地辨别谣言,给他人传播科学知识,是每个人应尽的义务。如今您已经知道了手机并不会使银行卡消磁。想必下次有人聊到这个问题的时候,您一定会给出科学的解答。相关的主题文章:
