Description

FIELD OF TECHNOLOGY

The utility model belongs to the class of devices used both in near field communications and in mobile communications.

BACKGROUND

The mobile subscriber identity module, commonly known as a SIM card, is used not only to provide communication services. A state-of-the-art SIM card, denoted by the term UICC in industry specifications, can be used in Near Field Communication (NFC) operations. Typical examples of NFC operations are payment for travel in vehicles, purchase of goods (services) at trade and service enterprises, and access to premises.

The GlobalPlatform organization has defined a security element (EB) - a component protected against hacking, used to ensure security and confidentiality, and to create working conditions for several applications to support various business models. EB can exist in different form factors, such as UICC, eSE, μSD, smart μSD and others. In particular, the Card Specification and its Amendments ^{1 are} known, (1 Technology Document Library - Secure Element (SE) // GlobalPlatform: The standard for secure digital services and devices. URL: https://globalplatform.org/ specs-library /? filter-committee = se (accessed: 11/15/2018)), defining the components of the electronic business card (cards), instruction sets, the order of transactions and interfaces, as well as the dynamic management of the card after issue; UICC Configuration and SE Configuration, which define the requirements for implementing Card Specification on the UICC platform and other security features, respectively.

On the one hand, the technical specifications of TS 102613 ² (2 TS 102613 // ETSI. URL: https://www.etsi.org/deliver/etsi_TS/102600_102699/102613/ (accessed: 11/15/2018)) and 102622 ^{3 are} known. (3 TS 102622 // ETSI. URL: https://www.etsi.org/deliver/etsi_TS/102600_102699/102622/ (accessed: 11/15/2018)) of the European Telecommunications Standards Institute (ETSI), defining the logical and physical interaction between the UICC and the external contactless interface (Contactless Front-end, CLF).

SD Association (SDA) documents are also known as the Advanced Security SD Extension Simplified Specification and the NFC Interface Simplified Addendum to the Physical Layer Simplified Specification ⁴ (4 Simplified Specifications // The SD Association. URL: https: // www.sdcard.org/downloads/pls/index.html (accessed: 11/15/2018)), which determine the basis of additional security systems on memory cards (SD cards) and the interface between the μSD card and the NFC controller, respectively.

The mentioned specifications assume the presence in the mobile device of a contactless interface external to the UICC or μSD card, including an NFC controller and an antenna.

On the other hand, we know about the devices, which are in the SD card form factor or (J.SD with built-in the NFC-capabilities: for example, NFC SD Card Toshiba's ⁵ (5 NFC SD Card Overview // Toshiba URL: . Https: / /pc.toshiba-asia.com/storage/memory-cards/wireless-cards/nfc-sdhc-card/overview.php (reference date: 15.11.2018)) and the LGM Card company SMK-Logomotion ¹ (1 LGM Card / / SMK-LOGOMOTION.

A device is known [Device with communication means and a socket for a chip: US Pat. 2625914 Ros. Federation: IPC Н04В 5/00, G06K 19/077 / WAN Jian (CN); patent holder CERTGATE GMBH (DE). - No. 2015141947; declared 04/02/2014; publ. 05/15/2017, Bull. No. 14], versions 14 and 15 of which include both communication means using wireless personal area network (Bluetooth) technology and near field communication (NFC) means designed to increase the communication range.

A product is known [MicroSD card combined with a SIM card: US Pat. 182209 Ros. Federation: G06K 19/077, H04M 1/725 / R.Yu. Andreev, E.L. Heikkinen, A.V. Sviridov, E.A. Zotov; patent holder LIGHT ELECTRONICS Limited Liability Company (RU). - No. 2017141389; declared 11/28/2017; publ. 08.09.2018, Bull. No. 22], intended for the simultaneous use of a SIM card and memory card in one telephone slot while maintaining operability and the possibility of replacing (removing) the product without damaging the product or phone slot.

With all the advantages of UICC that support near field communications, their disadvantages include the need to use a special class of mobile devices, usually called NFC phones, which are equipped with an external contactless interface. Although there are more and more NFC phones over time, it’s hard to expect all mobile devices to have an NFC controller and antenna in the near future.

Solutions based on the use of a μSD card with a built-in external contactless interface are free from the aforementioned disadvantages of UICC. However, these solutions ultimately limit the user of the mobile device, because they occupy the slot for μSD-cards, usually used to expand the memory.

The proposed utility model offers a solution to the above problems.

( ¹ TS 102221 // ETSI. URL: https://www.etsi.org/deliver/etsi_TS/102200_102299/102221/11.01.00_60/ (accessed: 11/15/2018))

IMPLEMENTATION OF A USEFUL MODEL

The technical solution can be implemented using the prior art. The case of the device can be made according to the technology used for the production of μSD-cards. The ability to integrate two microcontrollers into one small device and an external NFC non-contact interface can be demonstrated using the LGM Card as an example. Modern single-chip BLE systems are extremely small (for example, they can be packaged on a site measuring 2.66 by 2.56 mm), which makes it possible to place them along with other components inside a 4FF module measuring 12.3 by 8.8 mm.
