Hi:

I am attempting to do the following project.  If anyone has done a
similar project or part, there of  I would appreciate any advice or
suggestions you may have.

I need to do a cheap bar code reader, compare the code with some data
previusly stored in a EEPROM (may be serial EEPROM 96LC54),ask a code
password altrought a 3x4  keypad, compare bar code id with password
and if its rigth, open a door (don't forget first how store the
initial values for bar code id's), Im thinking in use the
PIC16C84-04/P

Thanks in advance

Use one of these cheap readers that go between your keyboard and the PC.

The reader does all the work and spit out characters.
