Abstract:
A drawer assembly, a financial transaction terminal and a method for manipulating the drawer assembly with respect to a financial transaction terminal. The financial transaction terminal uses a merchant card to record information pertaining to transactions between two parties, e.g., a customer and a merchant. The merchant card is held within the drawer assembly such that the merchant card is automatically inserted into the terminal when the drawer assembly is inserted into the terminal. Additionally, the merchant card is automatically removed from the terminal when the drawer assembly is removed from the terminal. The drawer assembly is removably connected to the terminal via a movable tab member. Depression of the tab member both releases the drawer assembly and applies pressure on the merchant card to thereby facilitate removal of the merchant card from the terminal. The drawer assembly and the merchant card can thus be inserted into and removed from a bottom side of the financial transaction terminal without requiring that the terminal be flipped over.

Description:
FIELD OF THE INVENTION 
     This invention relates generally to a point of sale financial transaction terminal and more particularly to a drawer for facilitating insertion and removal of a merchant card (smart card) and a method for manipulating the drawer and merchant card with respect to the terminal. 
     BACKGROUND OF THE INVENTION 
     A merchant card, i.e., smart card, is typically a credit-card sized plastic card with an embedded computer chip and a physical connector on the surface of the card. The chip may either be a microprocessor with an internal memory or a memory chip with a non-programmble logic. The use of smart cards (hereinafter “merchant cards”) has gained widespread acceptance as evidenced by the number of existing applications as well as those currently being developed, especially in the financial industry. One such application for the merchant card is a recordation of financial transactions between two parties (e.g., customer and merchant). 
     Point-of-sale (“POS”) financial transaction terminals are one type of device in which the above-described application may be transacted. In these types of terminals, a merchant card is typically housed within the terminal and collects information pertinent to financial transactions between a merchant and various customers. In this respect, POS financial transaction terminals possessing a merchant card are used, for example, to record the amount of the purchase made with a customer card (e.g., debit or charge card) and credited directly to the merchant card. In other words, the transaction amount is debited from the customer card and credited to the merchant card. Thus, the merchant card may be a useful tool to for a merchant to collect payment from his or her customers. As such, the merchant card may also be potentially valuable and thus a target for would-be criminals. 
     It is thus advantageous for the merchant to remove the merchant card for safe storage and/or deposit into a financial institution after the merchant card has recorded a sufficient number of transactions or at the end of a business day. In this regard, the merchant card may be removably placed within the financial transaction terminals. However, in an effort to deter would-be thieves, merchant cards are generally positioned in relatively hidden and inaccessible areas of the terminals. For example, merchant cards are typically positioned on a bottom side of the transaction terminals. As an added measure, merchant cards are typically housed within the terminal with a cover threadably fastened to the housing of the terminal. 
     Although these types of terminals may provide some level of protection against theft, they suffer from a variety of drawbacks and disadvantages. For instance, due to the positioning and fastening of the merchant cards, an increased possibility of merchant cards becoming damaged exists. That is, to remove the merchant cards, the entire terminal must be flipped over and a tool (e.g., screwdriver) is required to remove a cover member. Thereafter, the merchant card is manually removed from its connection to the terminal. This series of maneuvers can be quite cumbersome and the likelihood that the terminal and/or the merchant card will become damaged arises. 
     Known transaction terminals of this type also typically include a number of multi-Security Access Module (“SAM”) connectors, as well as, the SAMs inserted within the connectors. Additionally, these terminals include a merchant card connector and a merchant card. In certain situations, all of the above-cited components of the terminals must be accessed by the merchant (e.g., when the SAMs or merchant card must be replaced). In order to allow access to these components by the merchant, known terminals of this type are typically rather large. These types of terminals are rather disadvantageous because they require a large amount of counter space, which merchants generally require for other devices (e.g., cash register, scanners, etc.). 
     Moreover, in known transaction terminals of this type, the merchant card is normally inserted directly into the merchant card connector of the transaction terminal. This type of connection is disadvantageous because it positions the merchant card to a greater possibility of damage. For instance, because the merchant card is directly inserted into the merchant card connector without any outside support, the physical connector of the merchant card is susceptible of suffering surface damage. 
     Accordingly, there is a need for a financial transaction terminal in which the position of the merchant card is relatively hidden from view and which can be inserted and removed from the terminal without requiring that the terminal be turned over. Additionally, a merchant card cover which can be removed without a tool is desirable. 
     In addition, there is a need for a relatively small financial transaction terminal having sufficient space to allow for rather easy access to the multi-SAMs and the merchant card as well as the their respective connectors. 
     Furthermore, it is advantageous to have a terminal which effectively protects the merchant card during insertion thereof into the terminal. 
     SUMMARY OF THE INVENTION 
     In accordance with one aspect, the present invention pertains to a drawer assembly for covering multi-secure access module connectors and a merchant card connector housed within a cavity of a financial transaction terminal. The drawer assembly includes a first member and a second member. The first member is connected to the second member to thereby form a space therebetween for receiving and holding a merchant card. The second member includes a movable tab member having an upper surface and a lower surface, the tab member extending from an end of the second member. The drawer assembly is capable of securedly holding and positioning a merchant card for insertion into and removal from the financial transaction terminal and the drawer assembly is capable of interconnecting with the terminal. When the merchant card is positioned in the drawer assembly, a downward movement of the movable tab causes the drawer assembly to become released from the terminal, such that removal of the drawer assembly causes the merchant card to disengage from the merchant card connector to thereby facilitate removal of the merchant card from the financial transaction terminal. 
     In accordance with another aspect, the present invention relates to a financial transaction terminal for transferring credit information from a customer card to a merchant card. The terminal includes a housing having an upper side and a bottom side, a cavity for allowing access to at least one multi-secure access module connector and a merchant card connector formed in the bottom side of the terminal. The cavity has a generally downwardly extending lip provided at a front part of the cavity. The terminal also includes a drawer assembly capable of being removably inserted over the cavity to substantially cover the cavity. A merchant card is securedly and removably held in a space formed in the drawer assembly, such that the merchant card is inserted into the merchant card connector when the drawer assembly is generally fully inserted into the cavity and the merchant card is removed from the merchant card connector when the drawer assembly is removed from the cavity. 
     According to another aspect, the invention relates to a method of manipulating a merchant card with respect to a financial transaction terminal. The financial transaction terminal having a merchant card connector positioned in a cavity located in a bottom portion of the terminal. In the method, a drawer assembly having a tab member is provided for substantially covering the cavity. A rear end of the merchant card is positioned into a space defined in the drawer assembly, such that the merchant card is substantially securely maintained within the drawer assembly. The drawer assembly and merchant are inserted into the cavity to thereby substantially cover the cavity, such that the merchant card is substantially simultaneously inserted into the merchant card connector.

     DETAILED DESCRIPTION OF THE INVENTION 
     For simplicity and illustrative purposes, the principles of the present invention are described by referring mainly to an exemplary embodiment thereof, particularly with references to an example of a financial transaction terminal. However, one of ordinary skill in the art would readily recognize that the same principles are equally applicable to, and can be implemented in, any device that utilizes a removable information storing card, and that any such variation would be within such modifications that do not depart from the true spirit and scope of the present invention. 
     Financial Transaction Terminal and Drawer Assembly 
     As illustrated in FIG. 1, a financial transaction terminal  1  includes a keypad  2  for inputting information (e.g., the amount to be debited and credited) and a power switch  4 . Also illustrated in FIG. 1 is a tab member  46  of the drawer assembly  10  (see FIG.  2 ). As can be seen from this figure, the tab member  46  is easily accessible without having to flip the terminal  1  over. Additionally, the tab member  46  is fairly indiscreet, thus making it difficult for an outside observer (e.g., a would-be thief) to determine its functionality. 
     FIG. 2 shows the drawer assembly  10  in its removed state from the terminal  1 . As illustrated in FIG. 2, the drawer assembly  10  can be removed without flipping the terminal  1  over. As also seen in FIG. 2, the drawer assembly possesses a first member  12  and a second member  14 , both of which are described in greater detail hereinbelow. 
     FIG. 3 is similar to the view illustrated in FIG. 2, however, in FIG. 3, the terminal  1  and drawer assembly  10  are illustrated from the bottom sides thereof. As illustrated in FIG. 3, a cavity  9  is formed within the casing of the terminal  1 . The cavity  9  houses at least one, and preferably four multi-secure access module (“SAM”) connectors (not shown) and a full sized merchant card connector  7 . Although the multi-SAM connectors are not shown, FIG. 3 illustrates four SAMs  6  connected to the multi-SAM connectors. It is to be appreciated, however, that the present invention is not limited to four SAMs  6 , but rather, any reasonable number of SAMs may be utilized with the present invention. The cavity  9  is illustrated in FIG. 3 as possessing a pair of tongue-like projections  40  located on the side edges of outer rim of the cavity to facilitate insertion of the drawer assembly  10 . Additionally, the cavity  9  has a downwardly extending lip  80  formed at the front of the cavity  9  to facilitate locking of the drawer assembly  10  to the terminal  1 . The manner in which the tongue-like projections  40  as well as the downwardly extending lip  80  operate with respect to the drawer assembly  10  will be discussed in greater detail hereinbelow. 
     As illustrated in FIG. 4, the drawer assembly  10  includes the first member  12  and the second member  14 . Both the first member  12  and the second member  14  can be made entirely from any known suitable material, including, any known suitable plastic material, ABS, and the like. As seen in FIGS. 4 and 5, the second member  14  is positioned on top of the first member  12  and interconnected therewith. In this respect, the first member  12  and the second member  14  may be fastened together by any known means, for example, with adhesive, ultrasonic welding, and the like. 
     As further seen in FIG. 5, a space  13  is provided between the first and second members  12 ,  14  in respective relative centers thereof, such that a merchant card can be inserted therein. In this respect, according to a preferred embodiment of the present invention, the gap is made to be only slightly larger than a merchant card  8  (shown in FIG.  18 ). That is, the merchant card  8  may be housed somewhat tightly within the space  13 . As still further seen in FIG. 5, a female connector section  38  is formed on two sides thereof. In use, the female connector sections  38  receive the tongue-like projections  40  of the cavity  9  (shown in FIG. 3) to guide and securedly hold the drawer assembly  10  over the cavity  9 . 
     Referring now to FIGS. 9-11, although the first member  12  is illustrated as possessing four first mounting pins  22  and two second mounting pins  24  (FIG.  10 ), the present invention is not limited to this number of mounting pins, but rather may possess any reasonable number of first or second mounting pins, including no mounting pins. Referring further to FIG. 14, the second member  14  is depicted as including first apertures  54  and second apertures  62  corresponding in number to the first and second mounting pins  22 ,  24 . However, the present invention is again not limited to the illustrated number of first and second apertures  54 ,  62 , but rather, the second member  14  of the present invention may possess any reasonable number of first or second apertures, including no apertures. 
     Referring back now to FIGS. 4 and 5, the first and second apertures  54 ,  62  possess respective diameters which are only slightly larger than those of the first and second mounting pins  22 ,  24  such that when mated with one another, a frictional fit is provided therebetween. Additionally, once the first and second mounting pins  22 ,  24  are mated with the first and second apertures  54 ,  62 , the first member  12  and the second member  14  become aligned with one another, thus facilitating connection thereof. 
     As illustrated in FIGS. 4,  6 , and  7 , the first member  12  is equipped with an opening  36  through which a tab member  46  of the second member  14  extends. As most clearly seen in FIG. 6, the opening  36  is configured to allow the tab member  46  to travel vertically from an uppermost position which is substantially horizontal to a lowermost position near the bottom edge of the opening. Accordingly, the width of the opening  36  as only slightly larger than the width of the tab member  46 , but the height of the opening as substantially larger than the height of the tab member  46 . 
     FIG. 8 illustrates the bottom of the first member  12  as possessing a gripping surface  32  having a plurality of ridges  34  extending from a bottom surface of the first member. The gripping surface  32  may be formed integrally with the first member  12  or it may be formed separately and attached to the bottom surface thereof by any suitable means. The gripping surface  32  is positioned such that the removal of the drawer from the terminal  1  with the use of only one hand is facilitated. In other words, the gripping surface  32  provides a grooved surface for the user (e.g., merchant) to obtain substantial frictional grip on the drawer assembly  10  while depressing the tab member  46  with his or her thumb. Thus, along with the gripping protrusion  48  of the tab member  46 , shown in FIGS. 6-8, the gripping surface  32  provides a surface upon which the user can pull the drawer out of the terminal. 
     As also illustrated in FIG. 8, the first member  12  includes a pair of support members  30  extending from a bottom surface of the longitudinally extending section  16  in a direction substantially co-extensive therewith. Although a pair of support members  30  are illustrated, the present invention is not limited thereto and may be practiced with any reasonable number of support members. In use, the support members  30  support the drawer assembly  10  on a surface (e.g., a countertop) and facilitate insertion of the drawer assembly into the terminal  1  by assisting in alignment of the female connector section  38  of the drawer assembly to a height corresponding to the height of the tongue-like projection  40  of the terminal  1 . 
     Referring again to FIGS. 9-11, the first member  12  possesses a longitudinally extending section  16  and an upstanding section  18 . The upstanding section  18  is positioned substantially perpendicularly to the longitudinally extending section  16  and at an end thereof. The longitudinally extending section  16  possesses a lower surface  20 A and an elevated surface  20 B having a smaller length and width than the length and width of the lower surface. Thus, a substantially L-shaped surface is formed by the lower surface  20 A and the elevated surface  20 B. The L-shaped surface, along with the bottom surface of the second member  14  forms the female connector section  38  as illustrated in FIG.  5 . The lower surface  20 A and the elevated surface  20 B may be formed from a unitary sheet of material or may include two separate sheets which are fastened together in any known manner. For example the lower surface  20 A and the elevated surface  20 B may be secured together by adhesive, ultrasonic welding, or the like. 
     Also shown in FIGS. 10 and 11 are two protrusions  26  upstanding from the elevated surface  20 B of the longitudinally extending section  16 . The two protrusions  26  are positioned on the longitudinally extending section  16  generally away from the upstanding section  18 . The protrusions  26  are generally tapered along its front and rear surfaces and include a generally flat portion between the tapered sections. The protrusions  26  may be made integrally with the first member  12  (e.g., integrally molded as a single piece) or it may be formed separately and attached thereto in any known suitable manner, e.g., adhesive, ultrasonic welding, or the like. Additionally, the protrusions  26  may be made from any known suitable material including plastic, ABS, or the like. 
     FIG. 10 additionally shows an icon  28  positioned on the upper surface of the first member  12  illustrating the manner in which the merchant card  8  is to be inserted into the drawer assembly  10 . 
     FIGS. 12-15 show that the second member  14  possesses a substantially planar upper member  42  and a lower member  44 . The lower member  44  includes two arms  56  extending generally away from the tab member  46 . The arms  56  are connected to and spaced from one another by the upper member  42  and each includes a free end. Each of the arms  56  also includes a plurality of first apertures  54  and a plurality of second apertures  62 . The first and second apertures  54 ,  62  are dimensioned and positioned respectively to correspond and mate with the first and second mounting pins  22 ,  24  of the first member  12 . Along at least a portion of the length of the arms  56 , the arms  56  each possesses an inwardly slanted section  58 , as seen in FIG.  12 . The slanted sections  58  are intended to facilitate insertion of a merchant card  8  between the arms  56 . In other words, if a merchant card  8  were to abut against the slanted sections  58 , due to the angle of the slanted sections, the merchant card  8  would be urged downward and into a correct position. 
     As shown in FIGS. 12-13, at the free end of each of the arms  56  is provided a generally upwardly extending section  72  and a notched portion  70 . The notched portion  70  is intended to facilitate insertion of the tongue-like projection  40  into the female connector  38  formed in the drawer assembly  10 . That is, the notched portion  70  provides an enlarged opening having a height substantially greater than the height of the tongue-like projection  40  of the terminal  1  to thus make insertion of the tongue-like projection easier. As also illustrated in FIGS. 12 and 13, a plurality of ribs  60  are provided at a bottom surface of the arms  56 . The ribs  60  are intended to provide facilitation of ultrasonic welding of the second member  14  onto the first member  12 . 
     FIG. 14 further illustrates the second member  14  as possessing an ABS pad  90  molded on a bottom surface of the connecting member  82  for providing additional frictional contact with the top surface of the merchant card  8 . In a preferred embodiment of the present invention, however, the ABS pad  90  is not required but may be included to provide the additional frictional contact. 
     As illustrated in FIGS. 14 and 15, the tab member  46  of the second member  14  is connected to the upper member  42  and is preferably formed integrally therewith; however, the tab member may also be fastened to the upper member  42  by adhesive, welding, or any other known suitable means. In either instance, the tab member  46  is attached to the upper member  42  via a connecting member  82  which is separated from the upper member along its sides by a pair of slits  50 . The connecting member  82  is configured to resiliently maintain the tab member  46  in a generally horizontal position. Thus, when the tab member  46  becomes deflected, it is biased to return to the horizontal position. 
     As depicted in FIG. 13, an abutment structure  74  is formed on the tab member  46  such that the abutment structure extends above an upper surface of the tab member. The abutment structure  74  includes a slanted portion  76  and a substantially upwardly extending flat portion  78 . In use, the slanted portion  76  allows for the downwardly extending lip  80  to slide over the abutment structure  74  and the flat portion  78  provides a surface against which the downwardly extending lip  80  may abut. Once the downwardly extending lip  80  has passed completely over the abutment structure  74 , the downwardly extending lip  80  become essentially trapped between the flat portion  78  and the upstanding section  18  of the first member  12 . As described hereinabove, the tab member  46  additionally possesses a pair of protrusions  48 , each respectively positioned on the upper and lower sides of the tab member. 
     FIGS. 15-17 show the upper member  42  of the second member  14  as possessing a plurality of downwardly extending tabs  52  positioned and spaced substantially equidistantly in the transverse direction of the upper member. The downwardly extending tabs  52  are composed of a generally vertically extending section  64 , a generally horizontally extending section  66 , and an angled section  68  (FIG.  16 ). In use, the angled section  68  provides a surface upon which a merchant card  8  can abut to become positioned within the space  13  between the first and second members  12 ,  14 . Moreover, the generally horizontally extending section  66  is configured to apply a downward force on the top surface of the merchant card  8  when the merchant card is substantially fully inserted within the drawer assembly  10 . 
     Method of Manipulating the Drawer Assembly and Merchant Card 
     In order to insert the merchant card  8  into the financial transaction terminal  1 , the merchant card is initially inserted into the gap formed between the first and second members  12 ,  14  of the drawer assembly  10 . In this respect, a rear end of the merchant card  8  is positioned substantially over the upstanding protrusions  26  of the first member  12  and guided into the gap by the outwardly projecting arms  56  such that the physical connector  100  thereof extends beyond an outer end of the drawer assembly  10  as shown in FIG.  18 . In so doing, the downwardly extending tabs  52  of the second member  14  apply a downward force on the top surface of the merchant card  8  and the upstanding protrusions  26  of the first member  12  apply an upward force on the bottom surface of the merchant card. Thus, the merchant card  8  is maintained in a relatively tight manner within the space  13  of the drawer assembly  10 . 
     The drawer assembly  10  along with the merchant card  8  is then inserted into the cavity  9  of the terminal  1  while the terminal is in an upright position. In so doing, the female connector section  38  of the drawer assembly  10  is lined up with the tongue-like projection  40  provided on the edge of the cavity  9 . Once the female connector section  38  and the tongue-like projection are in general alignment, the drawer assembly  10  is inserted into the cavity  9  such that the tongue-like projection  40  is inserted into the female connector section  38  in a substantially tongue-and-groove fashion. According to a preferred embodiment of the present invention, the heights of the first and second mating sections  38 ,  40  are set at a predetermined value with respect to a common surface. This can be accomplished by varying the height of the support members  30  such that the heights of the first and second mating sections  38 ,  40  are the same when the drawer assembly  10  and the terminal  1  are placed on a substantially flat surface (e.g., a countertop). Thus, according to this embodiment, simply by orienting the drawer assembly  10  into the correct direction with respect to the cavity  9 , the drawer assembly will become automatically aligned with the cavity and thus insertion of the drawer assembly is easily facilitated. 
     As the drawer assembly  10  travels over the cavity  9 , the downwardly extending lip  80  travels over the slanted portion  76  of the abutment structure  74  thereby causing the tab member  46  to become somewhat deflected downwardly. Once the abutment structure  74  has substantially passed the ridge  80 , the tab member  46  returns to its original position due to the resilience of the connecting member  82 . Thereafter, the downwardly extending ridge  80  becomes substantially seated within the gap  84  formed between the upwardly extending flat portion  78  of the second member  14  and the upstanding section  18  of the first member  12 . Thus, the drawer assembly  10  is fully inserted and substantially entirely covers and is also releasably connected to the terminal  1 . During this process, the merchant card  8  becomes inserted into the merchant card connector  7 . Thus, the merchant card  8  can be properly connected without requiring that the card itself be independently inserted without any outside guidance. Moreover, it is unnecessary to flip the terminal  1  over to insert the merchant card  8  since alignment and insertion of the drawer assembly also causes the alignment and insertion of the merchant card into the merchant card connector  7 . 
     In order to remove the merchant card  9  and the drawer assembly  10  from the terminal  1 , the transaction terminal  1  is maintained in an upright position. Initially, the tab member  46  is depressed by applying a downward force on the upper surface of the tab member such that the abutment structure  74  is positioned slightly lower than the downwardly extending lip  80 . The drawer assembly  10  is then pulled away from the terminal  1  by simultaneously applying a downward force on the tab member  46  and an upward force on the gripping surface  32 . As indicated in the Tables shown hereinbelow, because the amount of force necessary to pull the merchant card  8  out from the merchant card connector  7  is less than that required to pull the merchant card  8  out from the drawer assembly  10 , by pulling the drawer assembly out of the terminal  1 , the merchant card is also removed therefrom. In this respect, therefore, it is unnecessary to independently remove the merchant card  8  from the terminal  1  after the drawer assembly has been removed. Moreover, it is unnecessary to flip the terminal  1  over to remove the merchant card  8  from the merchant card connector  7 . 
     The information contained in the Tables appearing below will now be discussed in greater detail. At the outset, it is relevant to note that all of the measurements enumerated in the following tables were taken with an IMADA™ force gauge FS-1 model no. 74242 for the measurements in kilograms (Kg) and a SHIMPO™ force gauge MF-50 model no. 40312 for the measurements in pounds (lbs). Separate force gauges were used to measure in pounds and kilograms to improve the accuracy and confidence in the readings. 
     In addition, in obtaining the force measurements enumerated in the Tables, the tab member  46  was not depressed and thus, no additional force was applied to the merchant card  8  during the force measurements. Accordingly, had the tab member  46  been depressed during the force measurements, a greater difference in the insertion and extraction measurements between the values enumerated in Tables 1 and 2 and Table 3 would have been noted. 
     Referring now specifically to the Tables appearing hereinbelow, Table 1 sets forth the insertion and extraction forces measured in kilograms in inserting and extracting a merchant card  8  into and out of the merchant card connector  7 . The results cited in Table 2 refer to similar force measurements as those recited in Table 1 except that these readings were taken in pounds. Both sets of measurements cited in Tables 1 and 2 were taken at or around room temperature. As can be seen from these Tables, four measurements were taken with each of the force gauges and an average value was determined for each set of readings.

     Table 3 enumerates the force measurements obtained in inserting and extracting the merchant card  8  into and out of the drawer assembly  10 . All of the measurements were obtained at or around room temperature. Reference is also made to FIG. 19 which illustrates the relative position of the trailing edge of the merchant card  8  with respect to the drawer assembly  10  during the force measurements. Accordingly, the reference designations appearing in the following tables (A, B, and C) correspond to like reference designations appearing in FIG.  19 . Additionally, in a similar fashion to the measurements enumerated in Tables 1 and 2, four separate measurements were taken with each of the force measuring devices for measuring both insertion and extraction forces.

     In comparing the results enumerated in Tables 1 and 2 with those cited in Table 3, it is rather apparent that the amount of force necessary to insert and remove the merchant card  8  from the merchant card connector  7  is substantially less than that required to insert and remove the merchant card from the drawer assembly  10 . Accordingly, when the drawer assembly  10  is extracted from the terminal  1 , the merchant card  8  is also extracted from the merchant card connector  7 . 
     Table 4 illustrates how heat cycling of the drawer assembly  10  and the merchant card  8  affects the amount of force necessary to insert and extract the merchant card  8  into and out of the drawer assembly  10 . For these measurements, heat cycling consisted of four (4) cycles, 18° C. to 50° C., over two days with a merchant card  8  installed in the drawer assembly  10 . Before and after heat cycling, a total of sixteen (16) force readings were obtained, eight (8) measuring insertion force and eight (8) measuring extraction force. Additionally, reference is made to FIG. 19 which illustrates the relative position of the rear end of the merchant card  8  with respect to the drawer assembly  10  during the force measurements.

     Although the values obtained in Table 4 are lower than those enumerated in Tables 1 and 2, it is to be noted that the measurements listed in Tables 1 and 2 refer to measurements obtained at or around room temperature. It is however, safe to assume that the measurements appearing in Tables 1 and 2 would have been substantially lower had the merchant card  8  and the merchant card connector  7  been heat cycled in the same manner as was done to the drawer assembly  10  and merchant card for the measurements obtained in Table 4. It is thus recognized that the results enumerated above suggest that the drawer assembly  10  of the present invention will provide sufficient force for reliable merchant card  8  extraction, even after temperature accelerated creep. In order to fully evaluate the effects of plastic strain and low temperature creep, additional parts will need to be available to modify or destroy during testing.
