Abstract: A card having an antenna, one or processors, and memory having stored thereon a first application and a second application configured to receive an input of the card and determine a request associated with the input. The card is further configured to activate, responsive to determining that the request is consistent with a contactless EuroPay-MasterCard-Visa (EMV) data standard, the first application. The first application is configured to communicate, via near field communication (NFC), data to the communicating device via the antenna based on the EMV data standard for payment purposes. The card is further configured to activate, responsive to determining that the request is consistent with a near field communication data exchange format (NDEF) standard, the second application. The second application is configured to communicate, via NFC, data to the communicating device via the antenna based on the NDEF standard for verification/identification purposes.

Abstract: A turbine includes an inner casing to which at least a stator vane of a turbine section is mountable, and an outer casing arranged around the inner casing in such a way that an outer cooling channel is formed between the inner casing and the outer casing. The outer cooling channel includes a fluid inlet through which a cooling fluid is injectable from an outer volume of the turbine into the outer cooling channel. The cooling channel includes a fluid outlet such that the cooling fluid is exhausted into an inner volume of the turbine. The fluid inlet is located with respect to the fluid outlet such that the cooling fluid inside the outer cooling channel includes a flow direction which has a component that is orientated in opposite direction with respect to a main flow direction of a working fluid of the turbine.
