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.

NFC Antenna Systems

We will help you with selection of the micro coil NFC antenna size and NFC antenna module specification, design and tuning. We can make prototypes NFC antenna modules tuned for your NFC products using particular NFC controller (and SE) – respecting your choice and the best performing NFC solution.
We have developed various combinations of micro coil NFC antenna modules. These NFC modules passed EMVCo (CE), MoNA and NFC Forum Power transfer (R/W) criteria in various environments – plastic, glass or metal.

NFC antenna design selection

We recommend to use micro coils in one of two basic designs:

  • A single antenna design uses one coil antenna for both RX (receiving) and TX (transmitting). Choose the size from our portfolio
  • Dual antennas design uses one coil as RX antenna and the second coil as TX antenna (to improve the isolation). For NFC controllers with very low isolation or to reach a specific criterion the coil used as TX antenna can be substitute by a miniature planar antenna.

NFC performance measurements

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.
