T-Mobile Embedded SIM

SIM cards may be small but they’re often not small enough to be embedded into certain devices. Fortunately T-Mobile has come up with a new embedded SIM system which will make it possible to build smaller connected devices like hospital monitors which can report back to the server. The use of silicon instead of plastic enables these SIMs to be about the size of a pinhead, making it a lot more space efficient. You can expect to see devices that use these SIMs in as little as 6 months, with the first being an energy meter from Echelon.
