The document discusses using smart microSD cards as an approach for near field communication (NFC) services. It proposes that smart microSD cards, which have a built-in secure element and optional NFC antenna, allow for contactless services and security tokens while giving end users control over apps and services. This approach offers benefits like the largest reach across devices, business independence for service providers, and a consumer-centric model focused on creating value for all parties involved. Specifications and underlying hardware for smart microSD cards are already available.
