Credit card slips

[midnightcaller]

I collect many of these slips. But I never bother to read it carefully. I just look at the amount.

This is a credit slip from woolworths.
I curious to know what all these numbers mean and why is it printed for all transactions on the receipt.

APL
TVR
TSI
AID

Thanks
