Netcom is a Chinese company which is trying to carve out a niche market for themself by developing a NFC [Near Field Communication] chipset inside a microSD card.
The technology gives the microSD card the ability to communicate via NFC as well as provide memory storage for the user.Â The NFC chip sits inside the microSD slot of the host.
The idea is bringing NFC technology for payment terminals to older phones which don’t have the NFC chipset or technology currently in them.
The Netcom solution does require a bit of attention to make it all work.Â First, the microSD slot of the host must be made of plastic.Â Most are, but it’s worth noting to look before you buy.
Next, the NFC chipset does require a small app loaded on the host so that communication can take place between the NFC chip itself and the host it’s sitting in.Â Which makes sense, as typically that app is embedded on the phone RAM when spec’d out during production for a “certified NFC” device.
Last, is the antenna coil required to sit inside the microSD card might be a bit small/short for communication of a distance more than 20mm from the terminal receiver.Â Again, not a big deal as we are talking about NEAR field communication, but worth noting before buying.
