For every person carrying on the business of money lending or operating a pawnshop,
an annual business tax in accordance with the business tax rate schedule shall be
charged; and each person is required to keep a book in which shall be entered at the
time of purchase, written legibly in the English language, a true and accurate description
of every article purchased, pledged with, or received by him; the name, residence,
and an accurate description of the vendor or person from whom received; the amount
paid for such articles; and the date and hour of purchase or receipt. Such books shall
be preserved intact for the period of one year from the date of the last entry therein;
and shall be exhibited upon request to any police officer of the city. The city council
shall have the power to revoke any such pawnbroker's license without notice, and the
money representing the unused portion of such license shall be forfeited to the city.
