The power trends parts use a couple "turns" of track on the PCB, with an
RM-4 core clamped over them. IIRC they operate at about 1MHz.

Got a need to read Bar codes?  http://www.barcodechip.com
Bi-directional read of UPC-A, UPC-E, EAN-8, EAN-13, JAN, and Bookland, with
two or five digit supplemental codes, in an 8 pin chip, with NO external parts.
