On wednesday I am speaking at the Sim alliance event in Berlin ..
After a long time of discussing NFC there is a lot of optimism .. but today we have a situation that rather than the market not evolvoing at all .. it is taking off in (at least) 3 directions ..
SIM(Operators), handset vendors(including Google) and Credit card companies
see this link from the Register about the issue
Essentially NFC can develop for interactions(the easier use case) and / or transactions
If for transactions, then you need a ‘secure element’
There are three ways to manage the secure element
a) Micro SD
b) SIM and
c) embedded(on device)
I am looking for the pros and cons of each
For ex – one may argue that the SIM would mean giving control to Operator but it also means that credientials are mainatined across handsets (assuming you want to remain with operator)
I dont know much about the embedded space ie who is doing it(Intel?) any device vendors(other than apple)
There is also a wider issue of trusted service manager
So my qs is:
a) Given the consideration of NFC for transactions(and granted that its not the first use case), what are the pros and cons of the approaches?
b) I know least about the ‘embedded’ approach. any comments on that welcome
