microSD card as micro HSM 

The secure microSD card is a physical platform on which you can develop a particular security modules. Two secure chips and external ISO 7816 interface of the secure microSD card can empower security and functionality of the security module and your end-to-end solution. Your solution features, functionalities and compliance with various certification schemas will depend on the choice of the secure chips, common properties of these secure chips, storage subsystem utilization and certified firmware of the secure chips. We will help to design customised secure microSD card or USB respecting needs for your further certification, e.g. CSP defined by BSI.

The secure microSD card hardware can be used in different applications as a hardware security module for – cash registers, FIDO U2F/UAF, (mobile) eID, ePassport etc.

USB Dongle – used as mPOS

NFC Secure USB dongle addresses segment of very small and small merchants with mobile phones irrespective of the mobile data connectivity they currently have. NFC USB dongle is quite independent on the phone itself. Phone’s OS is not required to provide security or operational features for payment acceptance. Payment functionality is inside the NFC USB dongle which has embedded NFC antenna and SAM module.
It is product for Acquiring bank, it supports existing POS infrastructures and it preserve all relations of current payment acceptance industry.

NFC USB Secure Dongle – used as Authentication device and contactless reader

NFC USB Secure dongle is a standard USB-A key that fits computer ports. It contains NFC antenna enabling contactless usage. It comprises SE that generates, stores and protects secure keys and certificates and performs cryptographic operations and store other sensitive data (passwords, logins, user’s identification etc.)

• a multi-purpose, hardware based authentication devicefor PC/notebook. As a possession factor it can be combined with knowledge factor (like password or PIN) and/or with inherence factor (typically biometric characteristics like fingerprints or face recognition). Because of its NFC antenna it can utilize inherence factor already used inside user’s NFC enabled mobile phone. This will enable highly secure and user-friendly two or three factor authentication.
• a contactless readerattached to user’s PC/notebook. By tapping a contactless chip plastic card to the NFC USB Secure dongle, sensitive data from the chip card can be securely transferred into the PC and used for various identification/authentication/authorization online use-cases.

Secure NFC microSD cards – used for mobile payments and transit 

We have developed a secure NFC microSD card with embedded two secure chips and NFC antenna – LGM Card.

NFC antenna for Mobile phones

One micro coil NFC antenna design starts with coil sized L:18mm x T:1,4mm x W:3,14mm. It fulfills performance criteria in CE and R/W mode.

Supported standards

• • ISO/IEC 14443 Type A, B, F (up to 848 kbit/s) with Active Load Modulation (ALM)
  • Compliant with NFC antenna performance requirements (RW mode) for India*: Power transfer at 0 and 1 cm in a position A – must pass both distances and in the rest of positions – B0, C0, D0 and E0 it must pass 2 out of 4 distances including card operation distance for DESFire EV2 tag – 18mm
  • RoHS compliant
  • NFC CE (EMVCo) and R/W mode (MoNA)

Miniature Paying Wearables

For miniature and metal (paying) wearables that contain a battery (e.g. NFC watches, key FOBS, rings, etc.) we recommend to use the smallest single coil antenna design (RX/TX), supporting NFC CE mode. For wearables without a battery we have patented solution using two miniature coil antennas that support a passive modulation.

Supported standards

• • ISO/IEC 14443 Type A, B, F (up to 848 kbit/s) with Active Load Modulation (ALM)
  • ALM and PLM
  • RoHS compliant
  • NFC CE (EMVCo)

Tiny devices

For luxury or miniature metal wearables with or without a battery and with size limits to place a standard NFC antenna – e.g. NFC enabled watches, bracelets, glasses, earphones, speakers, key FOBs, rings, USB dongles etc.; we recommend to use the smallest one coil antenna design (RX/TX), supporting NFC peer-to-peer mode.

Supported standards

• • ALM and PLM
  • RoHS compliant
  • NFC CE (EMVCo)
  • ISO/IEC 14443 Type A, B, F (up to 848 kbit/s) with Active Load Modulation (ALM)
    

NFC USB Dongle
Miniature NFC coil antenna can be embedded inside NFC USB dongle (see a prototype on the picture) and that will be connected to a mobile phone or PC/notebook – adding them a functionality of an acceptance device (merchant device).
NFC USB dongle can be attached to PC/notebook and support a multi factor authentication. It can comprise SE that generates, stores and protects secure keys and certificates and performs cryptographic operations and store other sensitive data (passwords, logins, user’s identification etc.)

Applications

• • Payments acceptance
  • NFC tags reading
  • HW token and multi-factor authentication enabler

Industry metal housed objects

The coil NFC antennas perform also in metal housing objects and in a complicated electronic environment.

Applications

• • Machine setting, locking or pairing over NFC

We have tested micro coil NFC antenna modules performance with various NFC controllers.

We have developed a specific measurement method for simulating micro coil NFC antennas performance in smartphones. We can compare NFC results of these micro antennas with NFC results achieved by the same original reference phones. Each measurement is performed in 5 positions – backside, display, up, left and right.

We use FIME Automatic RF test bench for EMVCo Level 1 Analog test.
For R/W mode performance we use reference MoNA tags and NFC SONY reader RC-S380.
We have experience from certification of the NFC secure microSD cards as a mobile payment product performed at FIME France and FIME India.

Below measurement results of micro coil NFC antennas are achieved while tuned with NXP chips PN80T or SN100.
