Kronegger NFC OEM Reader

Sometimes RFID needs to be integrated deeply with other functions and technologies. This can save costs and enable innovative formfactors that differentiate you

The typical options for embedded RFID are:

  • OEM modules
  • Deep integration based on reader ICs like NXP PN512, RC632 and controllers like 8-bit, ARM etc.
  • Very deep integration based on dedicated hardware designs

The choice depends on volume and special requirements like integration with other functions. We offer support for all those options . We care for issues like interoperability, conformity to radio laws, power consumption, special reading requirements, or firmware adaptations and we make your RFID project faster and more predictable.

Interoperability – Broad Tag Support

This is an incomplete list of the tags currently supported by our contactless readers:

  • Mifare 1k, 4k, Ultralight, Mini
  • New Mifare Classic with 7 byte UID
  • Mifare Desfire, 2k, 4k, 8k, EV1
  • ISO 7816 commands for Mifare Desfire
  • Mifare Plus, Plus-S, Plus-X
  • Smart MX
  • 14443A Smartcards including T=CL
  • 14443B Smartcards including T=CL
  • SRT512
  • Inside Micropass
  • 14443B Prime (GTML, Calypso)
  • ISO 15693
  • ICODE UID, SLI, SLI-S, SLI-L, EPC
  • MyD 01P, 02P, 10P, 10S (security not supported)
  • Legic Advant (14443A mode, ID only)
  • Felica

The list ist constantly growing and evolving to keep you up to date even in the future.Bottom line is, that you do not need to care about interoperability because our readers are multilingual.

Secure RFID Readers

Applications that need to be resistant against fraud and manipulation frequently use secure elements, SAMS or contact smartcards. We provide interfaces for ISO 7816, T=0 and T=1. Simultaneous support of up to 4 SAMs is provided upon request.

Examples of supported SAMS are:

  • Infineon Easy SAM
  • Desfire AV1 SAM
  • Mifare Plus AV2 SAM
  • S9TST SAM
  • Calypso C SAM
  • Flashcos SAM

Additional interface types like SWP, DCLB etc. are available upon request.

Paypass – The Heart of Contactless Payment

Paypass devices need to be certified according to EMV Contactless Specifications for Payment Systems.

In order to prepare your device for certification we take care of:

  • RFID frames, sequences and commands
  • Polling, anticollision and detection
  • Half duplex block transmission protocol
  • An overall design that performs within the specified operating volume

The last item is tricky for small antenna designs like on mobile devices or on compact terminals. We speed up your RFID project.

NFC

Start getting ready for embedded NFC using our OEM modules!

Typical options for embedded NFC are:

  • Reader Writer Type A,B,F,V and many nonstandard types
  • Card mode
  • Peer to Peer mode initiator or target
  • High level interface for exchanging NDEF records
  • Compatibility to range of standard NFC phones

50 Ohm Antennas

Whenever antennas need to operate remotely from a reader, 50 Ohm connections are prime choice . Reader and antennas are connected through an off-the-shelf 50 Ohm cable. 50 Ohm is frequently combined with multiplexing antennas. So one reader can drive several antennas sequentially.

Typical applications are:

  • ticketing machines offering several reading zones
  • checkin and information kiosks
  • printers with serious space constraints
  • applications where a broad range of antennas needs to be supported

Conformity to Radio Laws

As well known RFID and NFC devices need to conform to radio laws . Depending on the country different emission limits and measurement setups apply.As a preparation for a certification we offer pre-measurements during our development process to ensure rapid convergence to applicable norms and limits.

We speed up your RFID project.

High Power Antenna Fields

Special situations may require very strong antenna fields:

  • tags with small antenna coils like RFID tokens, coins or stickers
  • power consuming contactless smartcards like secure credentials, ID cards or passports
  • a combination of both small antenna and contactless smartcard

Just amplifying the field will not work. The challenge is that conformity to radio laws and receiver performance is adversely affected. Using our proven reference designs, a system approach and conformity testing a fast convergence to your design goals is ensured.

Low Power Readers for enduring Battery Operation

Typically RFID readers can drain a battery quickly. Our low power reference design reduces the idle consumption of a reader down into the microampere (!) range. This is the same magnitude as the self discharge of a battery . At the same time our smart sensing technologies will detect a card and power up the device immediately if a card is presented. The bottom line is that the battery of your RFID application will last very long.

Kronegger Chipsets

Chipsets provide a low cost option at high volume or at special integration needs such as very compact designs. However, for lower volumes usually OEM modules are preferable due to less integration effort.
