I am designing a vending machine-like product, and need to identify an
expert in electronic sensors.  The expert must be well-versed in a
variety of sensor technologies, from pressure sensors to RFID.  The
purpose of the sensor is to trigger a transaction each time an item is
withdrawn from the machine.

Just to let you know that possible help is at hand but I reserve my
services for a day or two to give researcher a chance to get paid.

Experienced in virtually every kind of sensor and at present working
on ATMs. Not, I confess, an authority on RFID -- just another
electronics app though.

Well researchers aren?t biting so would you like to post some details?
I shall have a look tomorrow.

Unless of course you mean you wish to physically employ a sensor expert.

Yes, I want to actually engage a sensor expert.  The question was
simply designed to identify one or more qulaified candidates, not to
get the end result.

Thanks

Ah, I read this wrong -- possibly others did too. So it?s really more
along the lines of specialist employment agencies. Can I suggest that
if no one answers, you cancel this query and re-phrase, including
country just to narrow it down.

Great point.  Thanks.
