This NFC tag has the contacts on the chip exposed.
I was thinking it may work similarly to OneWire, which if true should be doable
The standard for contactless smart card communications is ISO/IEC 14443. It defines two types of contactless cards ("A" and "B") and allows for communications at distances up to 10 cm (3.9 in). There had been proposals for ISO/IEC 14443 types C, D, E, F and G that have been rejected by the International Organization for Standardization. An alternative standard for contactless smart cards is ISO/IEC 15693, which allows communications at distances up to 50 cm (1.6 ft).
