Point of sale terminal with breakaway cable

Abstract

A handheld POS terminal is provided, which is wired to a secure base unit by a cable consisting of two pieces that are joined together by a plug-in connector. The plug-in connector has a pull-out force necessary to separate the connector that is greater than the weight of the POS terminal but less than the force necessary to damage the cable connections at the POS terminal or at the base unit. The cable may also include a coiled section, which acts as a spring, so that if the POS terminal is dropped, the coiled section brings the POS terminal gently to a stop before it hits the ground. If a customer drives away with the POS terminal still in the car, the cable will separate at the plug-in connector, preventing damage to the POS terminal.

DETAILED DESCRIPTION

(7) The drawing figures are intended to illustrate the general manner of construction and are not necessarily to scale. In the detailed description and in the drawing figures, specific illustrative examples are shown and herein described in detail. It should be understood, however, that the drawing figures and detailed description are not intended to limit the invention to the particular form disclosed, but are merely illustrative and intended to teach one of ordinary skill how to make and/or use the invention claimed herein and for setting forth the best mode for carrying out the invention.

(8) With reference to the figures and, in particular FIG. 1, a drive-through food service lane 10 conventionally comprises a plurality of kiosks 12 displaying a selection of menu items 14. Kiosk 12 conventionally includes a microphone 16 and a speaker 18 to enable a customer to communicate with the order taker to place a food order. The customer typically advances either to a payment window 20 or a payment and service window 22 where payment is made.

(9) With additional reference to FIG. 2, in accordance with the present invention, payment and service window 22 is equipped with a handheld POS terminal 24, which includes a credit card chip reader, magnetic strip reader, RFID, Bluetooth, near field magnetic or other communication device to allow the POS terminal to interface with a credit card, smart phone or other contact or non-contact payment device. POS terminal 24 also includes a signature capture screen and keypad for inputting the customer's signature and/or PIN for the purpose of credit card verification.

(10) With additional reference to FIG. 3, POS terminal 24 communicates with the merchant's payment processing system by means of cable system 26 which is composed of a first section 28 and a second section 30 joined together by a plug-in connector 32. First section 28 includes a base unit 34 which is adapted to be attached to a counter, wall, or other suitable surface inside of payment and service window 22. In the illustrative embodiment, base unit 34 is attached to the counter 36 of payment and service window 22 by means of a screw passing through an aperture 38 formed in base unit 34. First section 28 includes a plurality of connectors 40, 42, 44 to allow POS terminal 24 to communicate with a variety of payment processing systems.

(11) Plug-in connector 32 is composed of a male portion 32a and a female portion 32b which, when joined together provide the necessary data links between POS terminal 24 and the merchant's payment processing system. When assembled, plug-in connector 32 is held together by means of a snap ring 46 which provides a predetermined pull-out force necessary to separate plug-in connector 32. This predetermined pull-out force is substantially less than the force necessary to damage cable system 26 (e.g. by causing a cable separation at base unit 34 or at POS terminal connector 48. Preferably the predetermined pull-out force is less than half the force necessary to damage cable system 26, preferably 10% or less than force necessary to damage cable system 26. The predetermined pull-out force is, however, also greater than the weight of POS terminal 24 for reasons that will become apparent hereinafter. In the illustrative embodiment, POS terminal 24 has a mass of 300 g and the pull-out force necessary to separate plug-in connector 32 is from 110 N to 135 N (11-13 Kgf) or about 40 times the weight of POS terminal 24.

(12) Second section 30 of cable system 26 includes an elastic portion 50, having a predetermined length and a predetermined spring rate. In the illustrative embodiment, elastic portion 50 comprises a coiled section of cable. Elastic portion 50 is optimized to bring POS terminal 24 to a gentle stop above the pavement surface in the event POS terminal 24 is dropped. For example, as shown in FIG. 4, as shown in FIG. 4, in the illustrative embodiment the spring rate of elastic portion 50 is 3 kg per meter. In the event POS terminal 24 is dropped, the cable will exert a force of 300 g when extended to a length of 450 mm which is sufficient to suspend POS terminal 24 a distance D approximately 300 mm above the surface of the pavement, thereby preventing POS terminal 24 from impacting the hard pavement.

(13) With additional reference to FIG. 5, in the event a customer drives away with POS terminal 24 still in the vehicle, the pull-out force necessary to separate plug-in connector 32 will be exceeded and plug-in connector 32 will separate before any damage to cable system 26 or POS terminal 24 can occur. Software running on POS terminal 24 detects the loss of signal and sounds an alarm 52 to alert the customer that POS terminal 24 is still in the vehicle. Additionally, when the loss of signal is detected, POS terminal 24 may activate a GPS tracking device so that POS terminal 24 can be recovered.

(14) Although certain illustrative embodiments and methods have been disclosed herein, it will be apparent from the foregoing disclosure to those skilled in the art that variations and modifications of such embodiments and methods may be made without departing from the invention. For example, although in the illustrative embodiment elastic portion 50 is part of second section 30 of cable system 26, elastic section 50 may be incorporated into first section 28 in addition to or instead of second section 30. Accordingly, it is intended that the invention should be limited only to the extent required by the appended claims and the rules and principles of applicable law. Additionally, as used herein, references to direction such as up or down as well as recited materials or methods of attachment are intended to be exemplary and are not considered as limiting the invention and, unless otherwise specifically defined, the terms generally, substantially, or approximately when used with mathematical concepts or measurements mean within 10 degrees of angle or within 10 percent of the measurement, whichever is greater. As used herein, a step of providing a structural element recited in a method claim means and includes obtaining, fabricating, purchasing, acquiring or otherwise gaining access to the structural element for performing the steps of the method. As used herein, the claim terms are to be given their broadest reasonable meaning unless a clear disavowal of that meaning appears in the record in substantially the following form (As used herein the term ______ is defined to mean ______)
