Yes - it's called the Q-tag and you can find it on the QF website. As Piltdown Man says, the plan was for chipped boarding passes to replace the 'ATB' card but smartphones and the desire to save more money by having the pax print their pass/Smartphone pass took over very rapidly.
There are a number of companies now selling RFID and BlueTooth bag tags for the Pax but the e-tag is only really helpful to a carrier with a large domestic network - like Australia and the USA. Only then is it worth investing in auto tag readers at the airports. As always, it's the cost.
