Upgrade in our PC/SC SDK (release 1.20)

The release 1.20 of SpringCard PC/SC SDK is now available in the Download section of the website (direct link to latest version : http://www.springcard.com/download/find.php?file=pcsc-sdk). This SDK is meant to be used with our products in the SpringCard CSB6 Family (CSB6Prox’N’Roll PC/SCEasyFinger and CrazyWriter).

People working in the 'emerging' NFC field will be glad to discover the updated versions of NFCTool, a .NET based application (written in C#) that makes it easy to create or to read NFC Tags compliant with the SmartPoster specification (as published by NFC Forum). Command-line nfc_create utility is also very useful to encode batches of NFC Tags.

The Desfire support library (pcsc_desfire.dll on Windows) has been upgraded; it now fully supports all the new features of NXP Desfire EV1 smartcards: AES and Triple-DES with 3 keys (3KDES), ISO 7816-4 compliant directories and files, card-level configuration. NXP Mifare UltraLight C chips are supported easily thanks to a new library (pcsc_mifulc.dll). Also, we've added in the SDK the Calypso support library (pcsc_calypso.dll) and its related sample software. All those libraries come with C source code.

New command line utilities have also been written for the ones who want to master PC/SC from its very basis, or have portability in mind. Most our C examples now run on Linux without any modification.

Create and read NFC tags with SpringCard NFC Tool and NFC Decoder

NFC Tags in a nutshell

An NFC Tag is a regular ISO 14443 card (either a memory card or a microprocessor-based smartcard), holding a specific content. Depending on this content, the "reader" will perform automatically a predefined action. Typical actions are :

  • open a URL (Internet address),
  • dial a number or send an SMS (if the reader is a mobile phone),
  • launch a software,
  • etc...

NFC tags are for instance embedded in Smart Posters, a new media for advertisement. Users seing the poster and touching its NFC tag with their NFC-enabled mobile phone or smartphone they may receive easily coupons or detailed information, or be prompted to buy online the advertised goods.

NFC logo : identifies NFC Compliant devices

The NFC Tag logo has been designed by the NFC Forum to identify NFC Tags.

NFC Forum, the organisation in charge of NFC standardization, has registered 4 types of NFC Tags :

  • NFC Type 1 tags :  Innovision Research & Technology TOPAZ chips (proprietary communication protocol on top of ISO 14443-A modulation)
  • NFC Type 2 tags : NXP MIFARE Ultralight and Ultralight C chips (proprietary communication protocol on top of ISO 14443-A modulation)
  • NFC Type 3 tags : Sony FELICA chips (proprietary modulation and communication)
  • NFC Type 4 tags :  standard ISO 7816-4 smartcards using ISO 14443 A or B up to layer 4

NXP and Nokia also support using NXP MIFARE Classic (1k/4k) tags. Visit NXP's website for more information on how to make NFC tags using their chips (including MIFARE DESfire as Type 4 tags).

The format on the content stored in the tags is specified by NFC Forum in NDEF standard (NFC Data Exchange Format).

Getting started with NFC Tags thanks to SpringCard readers and software

SpringCard has developed a set of software -with sources included in the new release of the SDKs- to demonstrate how NFC tags are encoded and processed by SpringCard contactless readers.

Customize your tags using NFC Tool

NFC Tool is a desktop application (Windows) to encode and read common NFC tags. NFC Tool works with PC/SC readers (Prox'N'Roll, CrazyWriter or CSB6 namely).

NFC Tool allows you to read/write NFC content on your cards

An example of use of NFC Tool with a Mifare UltraLight Card

Easily read and write NFC content in your cards using NFC Tool : Choose between SmartPoster, Text or URI ; fill in your URL or Text ; encode it to generate the NDEF and write it to your card.

At the date of writing, NFC Tool supports the following tags :

  • MIFARE Classic cards (standard 1K/4K)  as NFC Type 2 tags ;
  • MIFARE UltraLight (MF0ICU1) and UltraLight C (MF0ICU2) cards as NFC Type 2 tags ;
  • TOPAZ by Innovision cards as NFC Type 1 tags.

NFC Tool can be found in our PC/SC SDK (C# application for .NET framework).

Read NFC tags on your Pocket PC using NFC Decoder

NFC Decoder is a lighweight application for Windows Mobile (Pocket PC) that allows you to open an URL from an NFC tag card. NFC Decoder works with either SpringProx-CF, SpringProx-CF UP or SpringWAP through SpringProx API. It supports MIFARE 1K, MIFARE 4K and MIFARE UltraLight or UltraLight C as NFC Type 2 tags.

Contactless ticketing and pre-payment using Mifare UltraLight C and Prox'N'Roll

Last saturday, SpringCard Prox'N'Roll PC/SC was the core component of the access control and payment system during the annual gala of french high-school École Centrale d'Électronique (ECE) located in Paris. NXP Mifare UltraLight C chips were embedded in the disposable wristbands (featuring the SpringCard logo) that were worn by 3000 attendees.

Starting from SpringCard SDK, ECE students working on the project have written in only a few days a dedicated cashier software (in C# for .NET). A clever use of UltraLight C security capabilities (3-DES authentication) allowed them to make sure that no money could be lost during the event.

The team appears in a short video that aims to promote the concept :
