There's a thousand non-contact ways of doing this...

Why not just have a Barcode on a plate on the back of the Trailer which is scanned from inside the cab?

An iButton powered by RF tuned circuit or inductive loop?

There's lots of ways where the target (trailer) can have a device attached which can be powered by the source (cab) without the nescessity of any contact wiring.

But there's also lots of ways of reading Data from a distance without the target being powered in any shape or form anyway (ie like a Barcode, or Optical Character Recognition etc etc).

Thanks Mel

This sounds a good idea which means the details of the trailer would on the barcode

Would there be anyone whom can point me to a good tutorial about using
a barcode reader with the PIC (Complete Novice )

Hello Isaac,
Microchip has an eeprom with 1 wire interface ( data, ground, power) the 11LC160 avail. in SOT and PDIP. You could rig a circuit with a nicad, a to92 regulator, a couple of diodes etc to provide power, and charge off the running lights or even a solar panel.

U are right just need suggestions

Use an IR transmitter on the trailer and IR receiver on the cab. Have the transmitter output the information at some time interval that is acceptable and maximizes battery life for the transmitter. No wires, No RF.
