Mobile NFC function can read the bank card information directly?

Speaking of security, I would like to ask, do not need a password, mobile NFC really easy to read the bank card information? How did this happen? Is NFC really going to be a hacker's self-service teller machine? With the NFC capabilities of the phone, it's easy to read information about a bank card, but note that unauthorized people using NFC phones to read bank card information will only lead to the bank card number, the ID number, the last 10 bills and the balance of the phone wallet being read. Although this part of the information is personal privacy, but this information can not directly lead to the theft of bank card funds. It is worth mentioning that, not all bank cards will be NFC acquisition of information, can be NFC mobile phone read information bank cards are IC chip bank cards, traditional magnetic stripe card can not read. Of course, this does not mean that the traditional magnetic stripe card is more secure, on the contrary, the old magnetic stripe card because it is easier to replicate, security is worse. Others worry that some shanzhai payment software or virus-infected mobile apps can use NFC to read bank card information, which is theoretically possible and does not need to worry too much. A few months ago, there was a security lab that counted, monitoring to the current hundreds of Shanzhai network of silver app can be phishing through the form of the user's personal information, through the simple inducement of fishing can be achieved, hackers do not have much need to increase this pair of mobile phone hardware has certain requirements of the limited function. So, mobile Trojans and Shanzhai Web apps are far more dangerous than NFC security, and given what we mentioned earlier, even if hackers can collect personal information via NFC, it will never cause your bank card to be stolen. In addition, NFC is limited by distance and it's hard for people to get information about your bank card from your wallet. For a streamlined answer, want to see extended friends can continue to read. Before the small series has not specifically introduced, today is a simple introduction to what is NFC Bar, NFC (Near-field communications, Near field Communication), also known as short-range wireless communication, is a short range of high-frequency wireless communication technology, Non-contact point-to-point data exchange between electronic devices is permitted. This technology is developed by contactless RFID (RFID), which is based on RFID and interconnect technology, developed by Philips Semiconductor (now-en-wisdom semiconductor), Nokia and Sony. Compared with our current use of more Bluetooth technology, NFC is more convenient, lower cost, lower energy consumption, establish a connection faster, just 0.1 seconds. But the use of NFC is much shorter than Bluetooth, some only 10CM, transmission rate is much lower than Bluetooth. NFC can complement Bluetooth technology, so it is widely used in the field of mobile phone, access control, card and Bankcard. For flash card under the traditional magnetic stripe bank card Well, small make up to admit that the top of a large section of nonsense are copied over, we do not look at all indifferent, just need to go straight to the theme of the good, first say what kind of bank card will be read to the information, ahead of ourmentioned that only the IC chip card will be read, such bank cards are generally with flashing signs. In cafes, restaurants using this chip bank card checkout only need to close the bank card reader, without the password to complete small payment. It is also because of this that we doubt the security of NFC. However, the previous small series has said that the mobile NFC can only read the information of the bank card, can not make payments and other operations, then mobile NFC can read what kind of information? Different bank cards can read information differently, using Alipay Client for NFC reading test, the results are as follows: In general, after reading the information, hand opportunity tip: can be opened fast payment, but because the opening fast payment only support real name account number and bank card belong to the same person, So you don't have to worry about your bank card being tied to someone else's account quickly. Finally come to the next distance, NFC mobile phone read information is extremely sensitive to distance, more than 5cm read out of the probability is greatly reduced, so as long as the bank card in the wallet, it is very difficult to read by a strange phone. Even in the subway crowded into photos, strange phone really read your bank card, you need to change the position and angle, it is more difficult than the direct theft of the wallet is much higher. So you don't have to worry too much about it.
