At the recent Mobile Asia Congress, GSM Association made an announcement that read as follows “45 major telecommunications operators have committed to support the implementation of Near Field communications imbedded in SIM cards.
It’s not the first time NFC enabled SIM Cards have been rumoured to materialise, however this time the rumour has substance! Inside Secure is an established leading player when it comes to developing smart cards and mobile technology, and as promised demonstrated the NFC Circuitry at the Cartes show in Paris last November. If it proves reliable with consistent signals then it could bring NFC capability to any GSM phone, and, more important, hand some control back to the network providers.
A few concerns have arisen as to whether there is enough space on what is already a small piece of technology to cram more on top. There is also the small problem of projecting signal out the device as the SIM is generally sandwiched between the battery and the motherboard. Top of the worry list is SIM cloning, and the ease of which this is being achieved its needless to say a few questions have surfaced about fraudulent activity and NFC SIM cards.
The reason NFC is so hard to develop and implement is because of the need for an induction loop, so it can run unpowered, as well as an antenna with which to communicate. So, Inside Secure have decided to give up on unpowered use entirely: if the SIM can’t draw power from the the device then the NFC component simply won’t work. Speculate to accumulate!
This is not the end of the world in terms of battery power as it is aimed to be used on the lower end more basic device where the battery life is everlasting, not these modern day battery hungry smart phones!
