Abstract

This article presents the WOLF (Wallet Open Library Framework) platform which supports an original interface for NFC developers called SE-QL . SE-QL is a SQL-like interface which eases and optimizes NFC secure application development in making the heterogeneity of the Secure Element (SE) transparent. SE implementation could be embedded (eSE) in the mobile device, or inside the SIM Card (UICC), or on-host software-based, or in the Cloud (e.g. through HCE); every SE implementation has its own interface(s) making NFC secure-application development extremely cumbersome and complex. Proposed SE-QL solves this problem. This article demonstrates the feasibility and attractiveness of our approach based upon an original high-level API.
