Hello all.... I have been given a number of gift vouchers for my birthday (lucky me!)..... They are in the form of a 7 digit alphanumeric code. For example:
Now there does not seem to be anything else needed and they last a year.
What's to stop some turnip from guessing and getting lucky with some kind of code generator and stealing my voucher! I know that probability is low of guessing but without knowing how the numbers are generated (digit increments or randomised etc) slightly wary of letting them sit for any length of time...
Overly cautious? Nothing to worry about? Or buy something quick!
