The new smart wallets hold at least 12 cards but users can have instant access up to six cards with the click of a button using the card access mechanism. For security, Ekster wallets block out all signals with its aluminum cardholder, keeping users fully protected against any data theft from RFID or NFC hijackers.

However, the proposed scheme only considers channel estimation errors in a fixed communication link, which ignores the multi-link channel estimation errors caused by open access mechanism in dense HCNs.

Groups have called on the European commission to investigate the company's tax affairs and Shell hit back saying, "No tax is levied on dividends from B shares, provided that they are paid via the so-called dividend access mechanism.This solved the problem for the shareholders in the British parent company and made it possible for Shell to unify in one headquarters location, The Hague.

In 802.11ah standard, the RAW mechanism that can allocate large numbers of stations with alternate channel time access can become an issue The channel access mechanism can make a station change into sleep mode and a packet should wait its turn when it's not time to access the channel, whereas real time services such as VoIP need quick access with low delay in its packet delivery.

In addition, the direct memory access mechanism allows overlapping data transfer with computation, thereby, reducing overhead in data transfer among memory hierarchy.
