The codes are just representations of large numbers but to make them friendlier we decided to use letter codes to encode them. I selected a collection of letters for these codes - they were picked as most clear when read out over the phone. Thought thinking back I do not know how S and F both made it into the final selection.
The letters are: acdefhjkqstuxyz
Each order code has only one credit code that will work with the order and they are generated using the unique hardware dongle that is attached to each clients machine.
We have had to send this to a client to complete their order...
TFDUJQ - AFUCKF - FXST
So, what other words can people make out of the letters? The letters can be used more than once. There is at least one ten letter word.
Next time, must remember to not include any vowels.
