1616) Why would a company issuing credit cards use a code that is much larger than the minimum length?
- AA) to allow for expansion, since the customer growth may increase exponentially
- BB) because the numbers are assigned sequentially and the codes should not use all possible numbers
- CC) so that a person would not be able to guess a credit card number and illegally use it to purchase goods
- DD) because the codes use the alphabetic derivation format
- EE) since the codes are used to do inquiries on the data within them
1717) Codes are:
