The card doesn’t come with, say, Pret A Manger’s wireless payment capability pre-loaded. But G&D said that its Micro SD is nonetheless a platform for implementing such features, whether that be to provide London Underground Oyster-style wireless entry into your workplace or simply as a cash alternative.

When slipped into a mobile phone, for example, the card will establish a secure communication link as soon as it comes within a few centimetres of a reader.

An availability date or price for the Mobile Security Card Micro SD hasn’t been given yet.
