So I am about to get the Nexus S 4g when it releases on Sprint and I was thinking. Would a HID security card (the kind you would use to open security gates and doors at work or appartment complexes) be able to be theoretically loaded into the NFC chip on the Nexus? Just wondering if this has been thought of or not, but it would eliminate having to carry 3 of the cards on my person for work and to get into my apartment complex.
