Current Situation for NFC Application Growth
• Attributes
─ Proprietary Vendor Solutions – Evolving from Card Market
─ Card Applet, Reader Firmware Pair for each Scheme
─ Multi-App Smart Card Paradigm Evolution to TSM
─ Chip Based Application and Credentials
• Scaling Challenges
─ Drives greater secure chip capacity requirements
─ Slower, less flexible, more expensive, less open
─ In short, tech-centric (old paradigm) drivers

The Future of Secure NFC Applications
• SE: Multi-applets, multi-credentials
• Storage: Drives increased SE capacity
• Auth: Multiple, different schemes
• Interop: Fragmentation, lack of standard
• TSM: More complex, heavy
•SE: One user credential
•Storage: Minimizes storage requirements
•TSM: Simplified SE Administration
•Flexible: Credentials in eSE or UICC
•Flexible: Fast to market for developers
