Definitely, compared with engineering one in at the start.
National has a chip that will do half an amp, and can be fully kitted out

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.
