NFC Business Card


NFC (near field communication) is a wireless technology which allows for data transfer such as text, number or any VCARD info between two NFC enabled devices.

  • NFC Business Card is combination of Traditional Business Card + NFC build inlay inside.
  • All V-card data can be encoded into NFC cards via data programing software/encoder.
  • Just a simple TAP with NFC Business Card to the phone, all data will be into the phone. So simple!
  • Phone with NFC has no need to install any App. Read NFC Card’s Data immediately. So easy!

NFC Business Card Concept:

  • A New generation of Business Card 
  • A New Fashion of Social Contact Tool
  • A New Weapon for Business Development 
  • A New Carrier for e-Marketing and Promotion
  • A New Business to Card Player who wants to make innovation

    Why Play It?

    • Card players wants to find more practical directions for RFID card application
    • More phones have been deploying NFC embedded, especially to Android and coming iPhones
    • Traditional business card is NOT convenient for people to type & input all data into the phone.
    • Business Card is able to bring more fun in social contacts. Impressive meeting is a good start!
    • URL data (web, video) can be easily encoded into NFC card. Amazing experience for marketing! 





Java Card refers to a software technology that allows Java-based applications (applets) to be run securely on smart cards and similar small memory footprint devices. Java Card is the tiniest of Java platforms targeted for embedded devices. Java Card gives the user the ability to program the devices and make them application specific. It is widely used in SIM cards, Banking IC cards, various ID cards etc.

Java Card is an industry-standard technology platform that was developed by Sun Microsystems (now Oracle) to enable Java-based applications - applets - to run on smart cards that support this standard.

Java Card Open Platform (JCOP) is an operating system for smart card or security sensitive embedded system environment. The functional architecture can be partitioned into 3 parts:

          1. Java Card, for development of applications, i.e. API and structure of card applets similar to class files
          2. Global Platform, for administration of applications and operating system, i.e. loading and access control
          3. JCOP proprietary features, mainly Java Card API extensions, i.e. ECC primitive calculation or MIFARE DESFIRE management

We RealSmart Technologies proudly provides following Java based smart card chips and even final cards with personalized. The chip forms cover from Contact, Contactless and Dual Interface.
