At present, the M1 (Mifare one) card is widely used in the application field of non-contact user identity authentication, but the dedicated undisclosed hardware logic algorithm adopted by it has been illegally cracked, and there are hidden dangers in user information, and the RFID with smart card swiping function -SIM mobile phone cards have gradually replaced M1 cards.
One card to achieve safe and multifunctional authentication
The RFID-SIM mobile phone card system is a new type of identity authentication and mobile payment business system that China Mobile is vigorously promoting. Each user can keep the original mobile phone number without changing the mobile phone. As long as a new RFID-SIM mobile phone card is replaced, on the basis of the original mobile phone communication functions, expansion functions such as access control, attendance, and small consumption can be realized. A mobile phone card in the true sense.
RFID-SIM card is a product that RFID technology penetrates into the mobile phone field. It is a brand-new mobile phone SIM card that not only has the mobile communication function of a normal SIM card, but also can be carried out through the antenna and RFID-SIM card sensor attached to it. Near-field wireless communication.
The RFID-SIM card supports two working interfaces, contact and contactless. The contact interface is responsible for realizing the application of the SIM card and completing the normal functions of the mobile phone card; the contactless interface can realize applications such as contactless access control, attendance, consumption, and identity authentication. Because the RFID-SIM card supports over-the-air download related specifications (such as OTA and WIB specifications), users can update the application in the mobile phone or recharge the account at any time, so that the mobile phone truly becomes an intelligent electronic wallet that can be used and charged.
The RFID-SIM card sensor is an RFID-SIM card reader, which can read user identity information from a mobile phone equipped with an RFID-SIM card and upload it to the corresponding server.
In terms of security, because the RFID-SIM card is a CPU card, the card contains an on-chip operating system (COS), which supports two-way authentication between the card and the sensor, which is safe and reliable. Thanks to the support of the mobile communication network, the mobile phone RFID-SIM card can realize the function of issuing and logging off over the air. At the same time, it can also provide users with value-added services such as attendance and consumption SMS bill reminders. The user can also check card information at any time through the STK menu in the mobile phone, and can perform corresponding operations on the card. Carrying a mobile phone can also effectively eliminate the phenomenon of lending others to use or taking the place of punching cards.
Access control system upgrade plan for base station/computer room
Solution 1: Dual card reader mode. Most of the existing base stations and computer rooms have built access control management systems, and M1 cards are generally used to open the door by swiping. On the basis of retaining the original access control system, Gosuncn has launched a system transformation plan for the RFID-SIM mobile phone card: an additional RFID-SIM single-mode sensor is installed at the place where the existing access control system swipes the card, and the user passes the RFID-SIM card The mobile phone swipes the card on the sensor to realize the door opening function. The user can also open the door by swiping the original IC card at the original IC card reader. This scheme protects the original investment through the compatibility transformation of the original system. The system composition is shown as in Fig. 1.
After the original access control system was reformed, the dual card reader mode was used, the original IC card reader and the newly added RFID-SIM single-mode sensor were retained, and the door was opened by swiping the IC card and the mobile phone with RFID-SIM card at the same time, and the center The card issuer is replaced with an RFID-SIM dual-mode card issuer, which supports the issuance of IC cards and mobile phones with RFID-SIM cards. It is particularly recommended that RFID-SIM cards also support over-the-air card issuance and over-the-air cancellation, which greatly increases convenience and efficiency.
Scheme 2: Single card reader mode. In response to the inconvenience in management and maintenance caused by the simultaneous presence of two sets of swiping systems, Gosuncn has also launched a more integrated system transformation plan—single card reader mode, which is still shown in Figure 1. The system is integrated with the newly added RFID-SIM card, and the original IC card swiping access control/attendance card reader is replaced with an integrated access control/attendance sensor that supports both IC card and RFID-SIM mobile phone swiping modes (ie RFID-SIM Dual mode sensor).
After adopting the single card reader mode, the RFID-SIM dual-mode sensor is adopted, and it supports both IC card and mobile phone swiping with RFID-SIM card. The central card issuer is replaced with an RFID-SIM dual-mode card issuer to support the RFID-SIM mobile phone card issuance.
For China Mobile’s newly built base stations and computer rooms, it is necessary to install an access control system that can support mobile phone card opening. Based on the consideration of one-step investment, we recommend that users adopt a single card reader mode.
Single/dual mode sensor meets access control/attendance/consumer system upgrade
During the transformation of the RFID-SIM mobile phone card in the China Mobile office building, we retained or replaced the original access control/attendance system according to the actual needs of customers, and upgraded with dual/single card reader modes to realize IC Card and RFID-SIM mobile phone card swipe the card to open the door and record attendance.
In addition, in response to China Mobile’s need to increase consumer functions in office buildings, Gosuncn launched its self-developed RFID-SIM consumer machine. The user only needs to select the corresponding product and swipe the mobile phone with the RFID-SIM card on the consumer machine to easily and conveniently consume.
Gosuncn independently researched and developed RFID-SIM card single/dual-mode sensor, which supports mobile phone RFID-SIM card swiping. The product has high sensitivity, strong anti-interference ability, stable performance, and can be well compatible with existing various An access control/attendance system that supports RFID-SIM card swiping in all areas of the sensor, which is very convenient to use. The system supports Weigand 26 and RS485 data output formats. Users only need to replace the card reader in the existing access control system to add RFID-SIM access control and attendance functions on the original basis. The matching access controller has a built-in SMS module and a 3G TD-SCDMA module based on China Mobile. It has a variety of ports and supports multiple transmission networking modes of IP, E1, SMS, GPRS, and TD-SCDMA.
The RFID-SIM mobile phone all-in-one card solution has been well applied in the new or upgraded access control systems of China Mobile’s office buildings, base stations, and computer rooms, and has been well received by users.
Through upgrading or directly building a new RFID-SIM mobile phone card system, the Internet of Things applications have been introduced into our daily work and life to realize identity authentication, small consumption, electronic passes, etc., and truly achieve “multi-card integration, one machine Pass”!
