Credit card security device having card invalidating electromagnet
First Claim
1. A credit card security device, comprising:
- a case having an access door for storing credit cards,locking means for releasably locking said door to secure the credit cards therein,detection means within said case for determining an entry into said case when said door is locked,invalidating means within said case for invalidating the credit cards,said detection means operating said invalidating means upon said entry,said detection means comprising;
a normally open electrical circuit for providing a current flow to operate said invalidating means;
switch means in said circuit and in at least one wall of said case for providing said current flow through said circuit to operate said invalidating means upon said entry, said switch means being normally open to preclude said current flow and closes upon said entry to said case through said wall, whereby to provide said current flow.

Abstract
A credit card security device which prevents credit card and bank card fraud. The device includes a case with an access door secured by a lock for storing the cards and a detection member within the case for determining an entry into the case when the door is locked. The detection member operates an electromagnet within the case upon the entry. The electromagnet scrambles the code within each credit card'"'"'s magnetic strip and thereby invalidates the credit cards for future use. The detection member comprises a normally open electrical circuit when the door is closed and locked and includes switches for providing a current flow to the invalidating electromagnet upon the entry. At least one such switch is a normally open pressure switch mounted in wall of the case which closes when the entry to the case is through the wall, thereby providing the current flow to the electromagnet. Another switch is associated with the lock and is open when the lock is unlocked, thereby precluding a current flow through the circuit, and which closes if the door is forcibly opened while locked, thereby providing the current flow to the electromagnet.

9. A credit card security device, comprising:
-
a case for storing a plurality of credit cards having an access door, a lock to secure said case, a circuit for providing a current flow to an electromagnet upon an entry into said case when said door is locked, and said electromagnet rendering the cards invalid for future use upon receiving said current flow, said circuit including a normally open pressure change detection member within a wall of said case, which closes said circuit when said entry into said case is through said wall whereby to provide said current flow. - View Dependent Claims (10, 11)

12. A credit card security device, comprising:
-
a case for storing credit cards having an access door, a lock to secure said case, a detection member within said case for determining an entry into said case when said door is locked comprising a normally open electrical circuit when said door is locked, and an invalidating member within said case and in said circuit for invalidating the credit cards, said detection member operating said invalidating member upon said entry and including a switch member for providing a circuit current flow to said invalidating member upon said entry, said switch member including a first sensor associated with said lock, said first sensor being closed when said lock is locked, said switch member including a second sensor operably connected to said access door, said second sensor being open upon closure of said door and closed upon opening of said door whereby to provide said current flow through said circuit when said door is open and said lock is locked, said switch member further including a pressure switch mounted in at least one wall of said case, said pressure switch being in a normally open position and closing when said entry into said case is through said wall whereby to provide said current flow, said lock including a non-conductive surface which causes said first sensor to open when said lock is unlocked and a conductive surface which causes said first sensor to close when said lock is locked, said invalidating member including an electromagnet in said circuit, said current flow energizing said electromagnet for invalidating the credit cards within said case.
