PC/SC on Linux and Mac OS X with Mono


One the goals of the Mono project is to make Microsoft .NET applications runnable on Unix systems. Using Mono, it is therefore now possible to maintain a single C#/.NET code base, that runs on Linux, Mac OS X and Windows.

In this context, SpringCard’s PC/SC SDK ( has been updated, so that it now enables developers to write PC/SC applications in C#/.NET, that can execute on Windows, as well as on Linux and Mac OS X platforms.

SpringField Colorado makes it easy to recognize the SpringCard smart reader you are using!

You know the scene in the movie where the support guys are desperately trying to help a customer configuring a very specific product, only to discover minutes after that the customer has a totally different product in hands? Since SpringCard offers a very wide range of products, and since most products look the same (well, there’s nothing that resembles more closely an OEM NFC/RFID device than another NFC/RFID device), we experience this frequently. Our customer’s technicians sometimes face the same situation, when they come to the field and don’t know whether a colleague has already upgraded a firmware, uploaded a new configuration, or not.

To ease the job of all support teams and maintenance technicians, we’ve introduced an exciting new feature in all the “smart readers” firmware (aka all /RDR and RFID Scanner products). Starting with FW version 1.69, the reader is able to communicate with an Android application (code-name “SpringField Colorado“) and sends its identifier, version, serial number… This application runs on Android 4.4 and later, provided that the smartphone supports NFC. It takes benefit of the NFC host-card emulation (HCE) mode.

HTTP client feature added to FunkyGate-IP/RDR

What is still possible: the Classical Access Control Architecture

SpringCard FunkyGate-IP/RDR is a network-attached wall smart reader, targetting physical Access Control and adopted by modern office buildings, airports, sensitive areas. The FunkyGate-IP+POE/RDR is the powered-by-the-network version. In a classical Access Control Architecture, the FunkyGate-IP/RDR acts as a TCP/IP server, and the Door Controller or the Access Control Central Computer connects to every reader as a client. The communication uses a custom client/server protocol, designed for reliability, security and speed.

SpringCard PC/SC solution for Android has been released

SpringCard R&D team is proud to release a simple software solution to add support for SpringCard USB PC/SC Couplers to Android tablets (or smartphone).


A Nexus 9 Android tablet, with a SpringCard Prox’N’Roll PC/SC reader on the USB port, and a Desfire contactless smartcard

The software is made of two parts:


The SpringCard USB PC/SC Service’s page on Google Play store

This software suite is compliant with all SpringCard USB PC/SC Couplers, for instance SpringCard Prox’N’Roll PC/SC, Prox’N’Roll HSP PC/SC, TwistyWriter HSP, CrazyWriter HSP, CSB HSP… Note that the current version of the Service and Library allows to work only with the Coupler’s contactless slot. Don’t hesitate to contact us if you have an interest into addressing the smartcard / SAM slots of the Couplers.

To communicate with a USB PC/SC Coupler -which is basically a USB device, the Android tablet (or smartphone) must provide a USB Host stack. This should be the case of all tablets running Android 3.1 and higher. We recommend Nexus 7 and Nexus 9 tablets, running Android 5.0 or 5.1, which are the reference platforms we use to develop and test the solution. An adapter cable is required to connect the Coupler if your tablet doesn’t provide a full-size USB host connector.

Tip: if you’re not sure whether your tablet supports USB Host or not, just install the Service and the Demo application from Google Play, and check that your SpringCard Coupler is correctly activated by your tablet’s system. Remember that the Coupler will be powered by the tablet’s battery. Some tablets could be powered (by their mains adapter) even when an USB device is present, but most don’t; choose your tablet accordingly if you’re designing a kiosk or public-use system that should be mains-powered 24/7).

New firmware for all SpringCard PC/SC couplers based on the H663 core

SpringCard has just released a new firmware version, tagged 2.00, for its H663 core.

The H663 core is a versatile contactless+contact module, which supports virtually all proximity/RFID HF chip cards (ISO 14443 & ISO 15693 standards, including Mifare, Calypso, etc), NFC-enabled mobile phones or other objects (ISO 18092, peer-to-peer in initiator mode, passive communication scheme), and could also accept up to 5 contact smartcards (ISO 7816, one ID-1 card and up to 4 SIM/SAM ID-000 cards).

SpringCard H663 is the foundation of the largest family of RFID/NFC USB PC/SC readers on the market:

  • The H663S and H663A “bare” modules (designed respectively for either a Symetrical – balanced or an Asymetrical – unbalanced antenna)
  • The H663-USB OEM PC/SC ready-to-use contactless coupler (H663 core + antenna)
  • The CrazyWriter HSP, a complete multi-slot contactless+5 contact PC/SC coupler made for OEMs
  • The TwistyWriter HSP, a contactless+ID-000 PC/SC coupler made for OEMs
  • The CSB HSP, a desktop PC/SC coupler featuring contactless, 1 smartcard slot and 3 ID-000 slots
  • The Prox’N’Roll HSP, a brand new version of SpringCard’s best selling desktop contactless coupler.

This new firmware version provides only a few new features, but introduces a new software architecture based on FreeRTOS which dramatically increases the device’s performance for a better transaction time – particulary when accessing numerous slots in the same transaction.


How to upgrade

To upgrade your H663-based product with this new version, please refer to our H663/H512 Firmware Upgrade Procedure.

The 2.00 firmware file is here: uc3b0256_rc663_h663_2-00.hex

(note for future readers: please always use the latest firmware version using this permanent link).

From 30/04/2015, all H663-based products will ship with this version (instead of earlier 1.81).

Some new feature

Adding the reader’s serial number to the slot names under Windows

Starting with version 2.00, the H663 family is able to insert the reader’s serial number in the name of the PC/SC readers as exposed by Windows’ SCardListReaders API call. On machines with numerous readers attached, this makes it possible to know which physical reader is actually bound to a logical slot without querying the reader through a SCardControl call.

To enable this feature, download the latest version of MultifConf; create a new project for the H663-product you own (CrazyWriter HSP typically), and in this project scroll down to “Misc. tricks”. Then find the “Insert the serial number in the name of the slots” entry and turn it ON. apply the configuration to the reader(s) (Project -> Write Configuration into Reader), restart the reader, and enjoy!




Using Mifare Classic EV1 with SpringCard PC/SC readers

NXP has recently started shipping a new generation of Mifare Classic chips, called Mifare Classic EV1 (part numbers MF1S50yyX/V1 for Mifare Classic EV1 1K and MF1S70yyX/V1 for Mifare Classic EV1 4K).

The chips are 100% compliant with earlier Mifare Classic 1K and 4K, with 2 subtle differences:

  • the kind of protocol-level ID to be used must be configured once for all during the pre-personalisation step. Possible choices are 7-byte UID, 4-byte fixed but non-unique ID, and 4-byte random ID,
  • the load modulation level could be set to ‘high’ or ‘low’.

In this short article we’ll show how to configure both the kind of ID and the load modulation.

Personalize UID usage

This command can be only issued once. The choosen configuration is then locked forever. If you have ordered Mifare Classic EV1 with a specific configuration, the command has been issued in factory and will always fail adterwards.

The Mifare Classic EV1′ “personalize UID usage” allows to select one of four different modes:

  1. UIDF0 (value 0x00): anti-collision and selection with the 7-B UID
  2. UIDF1 (value 0x40): anti-collision and selection with the 7-B UID plus a possible shortcut (select only the 4 first bytes and read block 0, bypassing the second step of the selection)
  3. UIDF2 (value 0x20): anti-collision and selection with a 4-B random ID
  4. UIDF3 (value 0x60): anti-collision and selection with a 4-B non-unique ID (calculated out of the 7-B UID)

The command code is 0x40 and must be sent in a CRYPTO1-ciphered stream, after a successfull authentication on sector 0.

To do so, here’s the sequence of commands that must be send to the reader in a SCardTransmit stream (you may for instance write a script for csScriptor). We assume that the card is in transport condition, i.e. that the key A of sector 0 (as well as all other sectors) is the transport key FF FF FF FF FF FF and gives full access to the sector.

# Load the transport key in the reader's volatile memory
FF 82 00 00 06 FF FF FF FF FF FF

# Get authenticated over sector 0 using the transport key as key A
FF 86 00 00 05 01 00 03 60 00

# Check that the authentication is OK by reading block 0
FF B0 00 00 10

# Send the 'personalize UID' command within an ENCAPSULATE APDU
# P1 = 0x01 -> ISO 14443-3
# P2 = 0x08 -> timeout = 125ms
# The last byte is the value to be set, here we choose 0x60 for UIDF3
FF FE 01 08 02 40 60

The reader returns 90 00 if the card acknowledges the command.

If you receive 6F 02 instead (CRC error), it is likely that the card has sent a NACK, meaning that the configuration has already been set and is therefore locked.

Set modulation strength

The Mifare Classic EV1’s “set modulation strength” command allows configuring the chip for either the strong modulation strength (default, value 0x01), or the weak modulation strength (value 0x00).

The command code is 0x43 and must be sent in a CRYPTO1-ciphered stream, after a successfull authentication on sector 0.

To do so, here’s the sequence of commands that must be send to the reader in a SCardTransmit stream (you may for instance write a script for csScriptor). We assume that the card is in transport condition, i.e. that the key A of sector 0 (as well as all other sectors) is the transport key FF FF FF FF FF FF and gives full access to the sector.

# Load the transport key in the reader's volatile memory
FF 82 00 00 06 FF FF FF FF FF FF

# Get authenticated over sector 0 using the transport key as key A
FF 86 00 00 05 01 00 03 60 00

# Check that the authentication is OK by reading block 0
FF B0 00 00 10

# Send the 'set modulation strength' command within an ENCAPSULATE APDU
# P1 = 0x01 -> ISO 14443-3
# P2 = 0x08 -> timeout = 125ms
# The last byte is the value to be set, here we choose 0x00 for weak strength
FF FE 01 08 02 43 00

rfidscan-tool : driving your Prox’N’Roll RFID Scanner’s LEDs and buzzer

The rfidscan-tool command line

The rfidscan-tool command line application is available for any OS that supports libusb, HID-API or hidraw.

We’ve tested it on:

  • Windows XP / Vista / 7 / 8
  • Mac OS X
  • Linux (Ubuntu, Debian, etc)
  • Raspberry Pi (on Raspbian distro)

rfidscan-tool has been inspired by blink1-tool, the command-line application that controls the blink(1) USB notification light. Most of the source code comes from this application. and therefore we use the same licence model.

Note for Mac OS X: currently the tool is able to send commands to the RFID Scanner, but fails to receive its response (IOHIDDeviceGetReport always returns a timeout error — without waiting). This issue is under investigation.

Binary download

To get rfidscan-tool for your machine, visit our github releases page, and search for a version supported by your OS / target CPU.

Here’s 4 direct links to the first public version (v14.11):

Source code download

To compile your own version of rfidscan-tool, just checkout the rfidscan project from github and compile the rfidscan-tool subproject. Something like the below will work 99% of the time:

# git clone
# cd rfidscan-tool
# make

For a Windows target, we provide .SLN projects to be opened with the (free of charge) Microsoft Visual C++ 2010 Express IDE.


On Windows, you may invoke the binary from any command line box without restriction.

On MacOS X and on most versions of Linux (including on Raspberry Pi), you will need to either run as root (sudo rfidscan-tool <...>) or install udev rules as described in

When running rfidscan-tool without any argument, it will print a help page like the one below.


Here’s the detail of all commands:

rfidscan-tool <cmd> [options]

rfidscan-tool list

List all connected RFID Scanners.

rfidscan-tool version

Show the RFID Scanner’s firmware version.

rfidscan-tool test

Perform a routine test on the RFID Scanner(s).

rfidscan-tool leds <red>,<green>,<blue> [–during <time_ms>]

Drive the RFID Scanner’s LEDs. Allowed values for the red, green and blue parameters are

  • off : the LED is switched OFF
  • on : the LED is switched ON
  • slow : slow blinking
  • fast : fast blinking
  • heart : “heart beat”
  • slowinv : slow blinking, inverted
  • fastinv : fast blinking, inverted
  • heartinv : “heart beat”, inverted

The during parameter is optionnal ans specify how long (in milliseconds) the specified value remains active, before the RFID Scanner goes back to the default sequence.

If this parameter is missing, the LED command lasts forever (at least until another LED command is issued).

rfidscan-tool leds-default

Let the RFID Scanner drives its LEDs itself as usual.

rfidscan-tool beep [during <time_ms>]

Switch ON the RFID Scanner’s buzzer for the specified time (in milliseconds).

rfidscan-tool read <addr>

Read the configuration register at the specified address.

rfidscan-tool write <addr>=<value>

Write the specified value into the configuration register at the specified address. Leavevalue empty to erase the register.

rfidscan-tool dump

Dump all the configuration registers.

Note: the “sensitive” registers (keys for the Master Card and password) are hidden by “XX” chars.

rfidscan-tool write-conf <filename>

Write the configuration registers from the specified file (use a file produced by MultiConf software).

Usage options

Values for [options] are

  • -d <device num> --devices <device num> : perform the command only to this device (from --list), default is all devices (same as -d all)
  • -q --quiet : suppress most output messages
  • -v --verbose : verbose debugging messages
  • -r --reset : reset the RFID Scanner (to apply the new configuration)
  • -p --password <password> : to access a RFID Scanner that is password-protected
