## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims benefit by way of PCT patent application No. PCT/CA12/000191, filed Mar. 2, 2012; U.S. patent application No. 13/410,831, filed Mar. 2, 2012; Canadian patent application No. 2,733,110, filed Mar. 3, 2011; and Canadian patent application No. 2,756,489, filed Oct. 28, 2011.
TECHNICAL FIELD
The present disclosure relates to parking meters and in particular to parking meters having contactless payment options.
BACKGROUND
Parking meters come in many shapes and sizes but are generally divided into two main types or classes: multi-space parking meters which are typically larger devices capable of managing the parking payment and control for typically six or more, or possibly even hundreds of parking spaces; and, single-space parking meters which are typically small devices capable of managing the parking payment and control of a single parking space, but also sometimes additional spaces, such as two, four, or six spaces which are located in close proximity to the parking meter.
For example, FIG. 1 depicts a conventional single space parking meter 100 installed on a pole 102. Single space parking meter mechanisms are typically installed in a protective housing on a pole 102 near a parking space. The protective housing components, which are directly exposed to the elements and the public, are traditionally separate from the actual parking meter mechanism (not shown). The protective housing components of previous single space parking meters 100 typically comprise a lower housing 104 that receives a removable parking meter mechanism. A cover cap 106 is placed over the parking meter mechanism and secured to the lower housing 104. The cover cap 106 may comprise a semi-circular opening no, covered by a transparent material through which a display of the parking meter mechanism is visible. In some previous single space parking meters the display is set back from the exterior surface of the cover cap 106, or the transparent material covering the opening. The lower housing 104 is typically secured to a coin vault 108 for storing coins received during operation of the parking meter 100. The coin vault 108 may be secured to the pole 102. The parking meter 100 is operated by inserting payment, either in the form of coins or payment cards such as credit cards, chip cards or electronic purse cards, into the parking meter 100 which then displays and counts down the purchased amount of parking time.
Parking meters are often located in unattended areas, and as such vandalism, tampering and theft are of concern. The protective housing, which typically comprises the lower housing 104 and the cover cap 106, provides protection for the components of the parking meter mechanism from vandalism, tampering and theft, as well as protection from the environment.
Numerous credit card companies have now issued contactless payment cards which allow the card holder to make payment at devices with the appropriate contactless card readers. Previous parking meters have employed contactless card readers that allowed receiving payment from a card without the need of the card reader coming into contact with the payment card. However, previous parking meters have incorporated the contactless card reader as a separate component or with other payment means, such as the coin chute. Alternatively, the card reader could replace other payment means entirely. Although the incorporation of contactless card readers in parking meters may provide flexibility in the payment options available to a user of the parking meter, the position of the contactless card reader within the parking meter provided unsatisfactory user interactions. For example, when a contactless card reader is positioned away from a display of a parking meter, it has been difficult to provide clear instructions using the display indicating where to make payment with the contactless card reader. In addition, a parking meter having a contactless card reader positioned away from a display may require a separate or additional opening in the housing of the parking meter, which may lead to more costly, complex and time consuming manufacturing of the housing, and may make the parking meter more susceptible to vandalism, tampering or theft.
There is therefore a need for a parking meter having an improved implementation for contactless payments.
SUMMARY
There is disclosed a parking meter comprising components for providing parking meter functionality; a display for displaying parking meter information; a metal housing for protecting the parking meter components from an environment, the housing comprising a display aperture through which the display is visible; and an antenna for a contactless payment reader arranged in or on the parking meter in close proximity to the display.
There is further disclosed a removable parking meter mechanism comprising components for providing parking meter functionality; a display for displaying parking to information; and an antenna for a contactless payment reader arranged in close proximity to the display.

DETAILED DESCRIPTION
FIG. 2 depicts illustrative components of a single space parking meter. The single space parking meter zoo comprises a lower housing 202, a cover housing 210 and a removable parking meter mechanism 230. The parking meter mechanism 230 may be partially received within the lower housing 202, which is typically secured to a coin vault (not shown) that is mounted on a pole (not shown) when in use.
When the parking meter 200 is assembled, that is, the parking meter mechanism 230 is at least partially placed in the lower housing 202 and the cover housing 210 is secured and/or locked to the lower housing 202, the parking meter mechanism 230 is enclosed in a protective housing and protected from the environment, vandalism, tampering, theft or other unauthorized access. When assembled, the parking meter 200 includes a display opening 240 through which a display 242 of the parking meter mechanism 230 is visible. The parking meter mechanism 230 may include a contactless payment reader for providing payment using a contactless payment card issued by the parking operator or by a bank or financial institution under one of the credit card brands, or a card conforming to the ISO 14443 standard, although other types of near field communication (NFC) are possible such as an NFC enabled mobile phone, smartphone, wrist watch, or other appropriate tag, or token.
The contactless payment reader comprises a reader module (not visible) comprising electronics for controlling the operation of the contactless payment reader. The reader module is coupled to a contactless reader antenna 250. The contactless reader antenna 250 may be provided as a thin flexible ring of copper wiring around the perimeter of a viewing area of the display. The contactless reader antenna 250 is depicted by a dashed line in FIG. 2 as it is located behind the display 242. The contactless reader may be provided on a single board or component that includes both the contactless reader module and the contactless reader antenna 250. Alternatively, the contactless reader module may be separate from the contactless reader antenna 250 and connected to it by a wire or wires. The contactless reader module is in communication with electronics of the parking meter mechanism responsible for the overall operation of the parking meter. Alternatively, the contactless reader module may be incorporated into the electronics of the parking meter mechanism responsible for the overall operation of the parking meter.
When a contactless payment card, or other contactless payment device, is placed in close proximity to the contactless reader antenna 250, the contactless reader module can read information from the contactless payment card, which can be provided to the electronics of the parking meter mechanism in order to receive payment. In order to process the payment from the contactless payment card, the electronics of the parking meter mechanism may communicate with a remote server using wired or wireless communication technologies in order to receive authorization of the transaction.
Previous parking meters have included a contactless type payment method using a contactless payment reader. However, there were disadvantages associated with the placement of contactless payment readers, or more particularly the contactless reader antenna, within previous parking meters. For example, the difficulties included difficulty in providing adequate space to place a contactless payment reader as well as difficulty in providing instructions to a user, while still offering other payment means. Having the contactless reader antenna located away from the display, as in previous parking meters, makes it more difficult to provide instructions to a user for where to place the contactless payment card for payment.
The parking meter mechanism 230 includes a contactless payment reader that has a contactless reader antenna 250 located directly behind the display 242, which allows for payment by way of a contactless payment card or device (not shown). The display 242 is located in close enough proximity to the exterior of the parking meter 200 such that the contactless payment reader is able to adequately read contactless payment cards or devices placed over, or in close proximity to, the display 242, and so the contactless reader antenna 250. The maximum read distance between the contactless payment card or device and the contactless reader antenna is typically a function of the size of the contactless reader antenna 250, the presence of any material, and its nature if present, between, or in the vicinity of, the contactless reader antenna and the contactless payment card of device, and other operating conditions of the parking meter 200. The distance in between the contactless reader antenna and the contactless payment card or device, as well as properties of any intervening material, may affect the probability of successfully reading the contactless payment card or device. Different applications may have different acceptable reading success rates and as such, may have varying acceptable distances between the contactless reader antenna and the contactless payment card or device. An adequate success rate for reading of contactless payment cards or devices by the contactless payment reader through the display 242 may be accomplished even with a double layer of a clear protective cover placed over the display 242. Since the contactless reader antenna 250 is placed behind the display 242, which is significantly more transparent to the wireless signals used by the contactless payment reader than housing components of the parking meter 200, which are typically made of metal, no additional openings or apertures need to be included in the housing components to provide adequate operation of the contactless payment reader. Thus, by placing the contactless payment reader behind the display 242, in addition to providing a convenient location for placing the contactless payment device to initiate payment, it is possible to provide housing components that provide greater security and environmental protection.
When making payment using the contactless payment reader, the display 242 may be used to display a logo, graphic and/or directions such as “Tap Here” or simply “Tap” as depicted, providing clear and convenient payment instructions to the user. The contactless reader antenna 250 is located sufficiently close to the display so that a user placing the contactless payment card or device in the vicinity of the display 242 as instructed by the display will have an acceptable success rate for reading the contactless payment card or device.
By placing the contactless reader antenna 250 behind the display 242, the amount of space required to offer this method of payment may be reduced, as the need of an additional opening or aperture in the housing components is eliminated. In addition, the display 242 and possible protective covering of the display 242 provide protection and ruggedness so as to allow the contactless payment reader to be deployed in unattended single space parking meters without the need for additional protection. Additionally, by placing the contactless reader antenna behind the display 242, the physical packaging of the parking meter mechanism 230 may be reduced to provide more freedom in the design of the parking meter 200, possibly allowing a smaller more appealing single space parking meter, which may be desirable given the large number of single space parking meters that may be present on a single street or block.
Placing the contactless reader antenna 250 behind the display 242 as described above may work acceptably well if the display 242 does not have a sufficient amount of metal to significantly impeded the RF signals. However, some displays, for example colour displays, may have a metal backing, impeding the transmission of RF signals.
FIG. 3 depicts illustrative components of a single space parking meter. The parking meter 300 is similar to the parking meter 200 described above; however, the contactless reader antenna 350 is placed on the front of the display 242. The contactless reader antenna 350 may be placed around the perimeter of an active section of the display that displays information in order to prevent obscuring the view of the display. The contactless reader antenna 350 on the front of the display 242 may be in sufficiently close proximity to the display 242 so that a contactless payment card or device placed in the vicinity of the display 242 as instructed will have an acceptable reading success rate.
The opening 240 in the parking meter housing, through which the display 242 is visible when the parking meter 300 is assembled, also allows the transmission and reception of the required RF signals at the contactless reader antenna 350 for the operation of the contactless payment. The opening 240 is sized so that the RF signals can pass through a non-metallic material used to seal the opening 240. As a result, the RF signals do not need to pass through the metallic housing, providing improved operation of the contactless payment reader.
FIG. 4 depicts illustrative components of a single space parking meter. The parking meter 400 is similar to the parking meters 200 and 300 described above; however, the contactless reader antenna 450 is placed on the interior of a material used to seal or cover the opening 240 in the parking meter housing through which the display 242 is visible. Typically, the external housing of the parking meter 400 is made of metal, which attenuates RF signals. The opening 240 is typically sealed using a transparent or semi-transparent material such as Lexan. The material used to enclose the opening 240 is typically transparent or semi-transparent to RF signals.
As depicted in FIG. 4, the contactless reader antenna 450, represented by a dashed line, is placed on the interior side of the material sealing the opening 240. The cover 210 may need to be separated from a lower portion 202 of the parking meter 400 in order to remove the parking meter mechanism 230. The contactless reader antenna 450 may be attached to the contactless reader module of the removable parking meter mechanism 230 by a detachable connection 452, 454. As such, when removing the cover 210, the contactless reader antenna 450 can be detached from the removable parking meter mechanism 230 and then reattached when assembling the parking meter 400.
FIG. 5 depicts illustrative components of a single space parking meter. The parking meter 500 comprises a meter housing 502 that encloses a parking meter mechanism and protects it from the environment and vandalism. The meter housing 502 is typically made out of a metal or metal alloy and comprises one or more apertures providing windows to internal components, including a solar panel opening 510 through which a solar panel 512 may be visible. As depicted, the meter housing 502 includes a display opening 504 through which a display 506 is visible when the parking meter 500 is assembled. The display opening 504 in the metal housing 502 is typically sealed with a transparent or semi-transparent protective material such as Lexan. The parking meter 500 may include a solar panel opening 510 in the housing 502 in which a solar panel 512 can sit, or through which a solar panel is visible.
The display 506 is located behind the display opening 504 so that it is viewable when the parking meter 500 is assembled. The display 506 includes a contactless reader antenna 508 surrounding a perimeter of the display 506. The reader antenna 508 is located within the display opening 504, providing a transmission path between the antenna 508 and the contactless payment device that is not impeded by the metal of the meter housing 502. Although described as being located around a perimeter of the display 506, it is contemplated that the contactless reader antenna 508 could be located in different locations in or on the parking meter and arranged in sufficiently close proximity to the display 506 so that a contactless payment device placed in the vicinity of the display 506 has an acceptable success rate for reading the contactless payment device.
FIG. 6 depicts illustrative components of a single space parking meter. The parking meter 600 comprises a meter housing 602 that encloses a parking meter mechanism and protects it from the environment and vandalism. The meter housing 602 is typically made out of a metal or metal alloy and comprises one or more apertures providing windows to internal components. As depicted, the meter housing 602 includes an opening 604 through which a display 606 is visible when the parking meter 600 is assembled. The opening 604 in the metal housing 602 is sized such that the display 606 is visible, and a section which incorporates a plurality of buttons 614 for controlling the parking meter 600 is exposed.
The display 606 is located behind the opening 604 so that it is viewable when the parking meter 600 is assembled. The display 606 includes a contactless reader antenna 608 surrounding a perimeter of the display 606. The reader antenna 608 is located within the opening 604 which is covered by a material providing a low attenuation of RF signals, providing a transmission path between the antenna 608 and the contactless payment device that is not impeded by the metal of the meter housing 602.
Although described as being located around a perimeter of the display 606, it is contemplated that the antenna 608 could be located in different locations in or on the parking meter 600 and arranged in sufficiently close proximity to the display 606 so that a contactless payment device placed in the vicinity of the display 606 has an acceptable success rate for reading a contactless payment device.
FIG. 7 depicts illustrative components of a single space parking meter. The parking meter 700 is substantially similar to parking meter 600; however, the contactless reader antenna 708a is depicted as being located on an interior side of the material used to seal or cover the opening 604 and in close proximity to the display 606. Additionally or alternatively, a second contactless reader antenna 708b may be included on the interior side of the material used to seal or cover the opening 604 and surrounding the input components (i.e., buttons) 614 in close proximity to the display 606. With the contactless reader antenna 708a or 708b located on the interior side of the material used to seal or cover the opening 604, it may be connected to the electronics of the parking meter mechanism using a detachable connection.
Although described as being located around a perimeter of the display 606, it is contemplated that the antenna 708a could be located in different locations in or on the parking meter 700 and arranged in sufficiently close proximity to the display 606 so that a contactless payment device placed in the vicinity of the display 606 has an acceptable success rate for reading a contactless payment device. Likewise, although described as being located around the input components 614, it is contemplated that the antenna 708b could be located in different locations in or on the parking meter 700 and arranged in sufficiently close proximity to the display 606 so that a contactless payment device placed in the vicinity of the display 606 has an acceptable success rate for reading a contactless payment device.
Various possible positions of the antenna within the opening of the parking meter have been described above with reference to FIG. 7. Although the possible positions were described with regards to a single opening in the parking meter, a contactless reader antenna may also be positioned within or about a second opening separate from the opening for the display and still be in sufficiently close proximity to the display to facilitate clear payment instructions. For example, and with regards to FIG. 5, the contactless reader antenna could be placed in proximity to the solar panel opening 510, on the solar panel 512, on a cover of the solar panel opening 510, over the top surface of the solar panel 512, or a combination of one or more of the foregoing.
Alternatively, the contactless reader antenna could be placed on an exterior side of the parking meter, for example, over a protective cover of the display opening 504 or the solar panel opening 510. If the contactless reader antenna is placed on the exterior of the parking meter, it may be located at the same height, or slightly elevated relative to the metal housing surrounding the opening. The contactless reader antenna may be protected by a plastic bezel that encapsulates the contactless reader antenna and securely attaches to the parking meter.
Although the solar panel opening is described above as an opening, it may be provided by an indentation such that a solar panel and covering may rest flush with the rest of the housing. If the solar panel opening is provided by an indentation in the metal housing, the properties of the contactless reader antenna and/or the contactless reader module may be adjusted in order to account for the location of the metal.
FIG. 8 depicts illustrative components in a multi-space parking meter. The multi-space parking meter 800 provides metering functionality to a plurality of parking spaces. The multi-space parking meter 800 may be a pay and display type meter in which payment is made by a user and a printed ticket is displayed on the user's vehicle. Alternatively, the multi-space meter 800 may be a pay by space or pay by plate type of meter, in which payment is made and associated with a specific parking space or license plate. Regardless of the type of multi-space meter, the meter 800 typically comprises a metal cabinet or enclosure 802 that encloses the components of the parking meter. Components of the multi-space meter may be located or mounted within the enclosure 802 at convenient locations. In contrast to a single space meter, where a parking meter mechanism is typically removable as a unit, the mechanism of the multi-space meter may comprise the various components that provide parking meter functionality. The cabinet 802 includes a payment section 804 comprising input means 806 such as buttons and/or keypads, for controlling operation of the parking meter, one or more payment means 808 such as credit card, debit card and/or smart card readers and coin chutes, and a display 810 for displaying parking information. The multi-space parking meter 800 further includes a contactless payment reader that includes a contactless reader antenna 812 located in sufficiently close proximity to the display 810 so that a contactless payment device placed in the vicinity of the display 810 has an acceptable success rate for reading a contactless payment device.
The contactless reader antenna 812 is depicted as being located about a perimeter of the display 810. It is contemplated that the contactless reader antenna 812 could be located in different locations in or on the parking meter 800 and arranged in sufficiently close proximity to the display 810 so that a contactless payment device placed in the vicinity of the display 810 has an acceptable success rate for reading a contactless payment device.
The specific design of the contactless reader antenna may vary depending on numerous factors, including the size of the opening within which the antenna is located, the proximity of the contactless reader antenna to the metal of the parking meter housing, whether or not the opening has a metal backing, etc. Further, the wires or wire traces forming the contactless reader antenna may also vary, for example, if the contactless reader antenna is placed over the viewable portion of the display or solar panels, the wires or wire traces may be sufficiently small so as to not obstruct the view of the display, or functioning of the solar panel.
FIG. 9 depicts an illustrative contactless reader antenna. The contactless reader antenna 900 comprises a plurality of connected traces forming a single electrical wire. As depicted, the contactless reader antenna 900 comprises a tail portion 902 that is used to connect the contactless reader antenna to the contactless reader module and a loop portion 904 that surrounds a viewable area 906 of the display of the parking meter. It is noted that the loop portion 904 terminates at an inner location 908, however this inner location 908 is electrically connected to one of the traces of the tail portion 902. This electrical connection, depicted as wire 910, between the inner location 908 of the loop portion 904 and the tail portion 902 is electrically insulated from the other wires or wires traces of the loop portion 904.
The above has described placement of a contactless reader antenna within a parking meter. Advantageously, the antenna placement has been described as being located in close proximity to a display, facilitating easy instructions for the use of the contactless reader. As will be appreciated, single space parking meters commonly found in North America, and other parts of the world, have a common outer housing made of a high strength metal, such as ductile iron, nickel or zinc. The commonly shaped housing allows different parking meter mechanisms to be received within the housing. While convenient for replacing the parking meter mechanism, the use of a common housing reduces the locations that the contactless reader antenna may be placed, as the lower metal housing is common and generally already installed on the street. As such, it is desirable to locate the contactless reader antenna in a location on the replaceable parking meter mechanism that is not covered by the common lower housing when the parking meter is assembled. As described above, the contactless parking meter antenna may be located within an aperture of an upper housing or cover of the parking meter mechanism. The aperture has been described above as being provided for the parking meter display and/or input controls of the parking meter. Depending upon the size of the display aperture, the efficiency of the contactless reader antenna may be less than ideal. For example, if the display aperture is relatively small, a contactless reader antenna that surrounds the display may still be located in close proximity to the metal housing of the cover. The close proximity of the metal to the contactless antenna may adversely affect the operation of the contactless reader antenna and the antenna may not be able to achieve a desired performance level.
It is possible to locate the contactless reader antenna in a location other than surrounding, or immediately adjacent to, the display. For example, the parking meter 500 includes an opening or aperture 510 for receiving a solar panel 512. As depicted in FIG. 5, the solar panel aperture 510 is relatively large compared to the display opening 504, while still being located in close proximity to the display. It is contemplated that the contactless reader antenna may be located within the solar panel aperture 510.
FIG. 10 depicts a cross section of the solar panel aperture 510 of FIG. 5 taken along line 10-10′. FIG. 11 depicts the component layers within the solar panel aperture of FIG. 10. As depicted in FIGS. 10 and 11, a solar panel assembly moo located within a solar panel aperture is depicted. As depicted, the solar panel aperture is provided within a metal housing 1002 of the parking meter. The bottom of the solar panel aperture is lined with a radio frequency (RF) shielding material 1004 that absorbs RF signals, such as those radiated by the contactless antenna. The solar panel assembly is received on top of the RF shielding 1004 and includes a solar panel 1006 that is sized to be received within the solar panel aperture. A lower transparent covering 1008, such as a 1/16′′ Lexan covering, is located on top of the solar panel 1006. The contactless reader antenna 1010, which may be a coiled loop of very fine gauge copper wires shaped in a 2′′×3′′ loop, is located on top of the lower transparent covering 1008. A second transparent covering 1012, such as a 1/16′′ Lexan covering, may be placed on top of the contactless reader antenna 1010. The solar panel assembly, comprising the solar panel 1006, the first transparent covering 1008, the contactless reader antenna 1010 and the second transparent covering 1012 may be secured in place within the solar panel aperture by a metal covering plate or bezel 1114. The covering plate has an aperture through which light can pass through to the solar panel 1006. The covering plate may be secured in place using one or more screws or bolts 1016 that pass through the solar panel assembly and the RF shielding layer 1004 into the bottom of the solar panel aperture. Although depicted as passing though the different layers, it is contemplated that the individual layers may be sized such that the screws or bolts do not pass through them.
Advantageously, the size of the solar panel aperture allows the contactless reader antenna to be located a sufficient distance away from the surrounding metal housing to provide improved reading characteristics. Further, the placement of the contactless reader antenna 1010 on top of the first transparent covering 1008 and the solar panel 1006 provides a gap between the contactless reader antenna 1010 and the metal 1002 of the bottom of the solar panel aperture. Further, the RF shielding 1004 located in bottom of the solar panel aperture further improves the operation of the contactless reader antenna 1010. While the contactless reader antenna 1010 is located above the solar panel 1006, and so will block some light that would otherwise be incident upon the solar panel, the amount of light blocked may be negligible due to the fine gauge of the copper traces of the contactless reader antenna.
As described above with reference to FIGS. 10 and 11, a contactless reader antenna may be located within a solar panel aperture. As depicted in FIG. 5, the solar panel aperture 510 may be located in close proximity to the display 506 of the parking meter, possibly simplifying the instructions for the use of the contactless reader antenna. For example, the display 506 may be used during a payment to display easy-to-use instructions to a user for effecting contactless payment via the contactless reader antenna located within the proximal solar panel aperture 510. Locating the contactless reader antenna within the solar panel aperture 510 may also provide improved operating characteristics when compared to locating the contactless reader antenna within a possibly smaller display opening.
In addition to providing adequate operating characteristics, it is further desirable to provide a single space parking meter that is simple to manufacture and easy to maintain. It is possible to incorporate the contactless reader antenna and the solar panel in a single component that can be easily installed and/or replaced within a single space parking meter.
FIG. 12 depicts a layered construction of a solar panel assembly as described with reference to FIGS. 10 and 11. The solar panel assembly moo may be manufactured into a single component, allowing easy replacement of the solar panel component in the parking meter. As depicted in FIG. 12, the solar panel assembly moo may comprise a stacked arrangement of the solar panel 1006, the first transparent covering 1008, the contactless reader antenna 1010, and the second transparent covering 1012.
The solar panel assembly may be installed in a parking meter by first placing a layer of RF shielding material in the bottom the solar panel aperture; placing the solar panel assembly within the solar panel aperture, and attaching the contactless reader antenna to electronics of the parking meter as appropriate; and securing the solar panel assembly within the solar panel aperture with a cover plate or bezel.
As described above, a parking meter may be provided with a contactless payment means having a contactless reader antenna arranged within an opening in the metal housing of the parking meter. As described, the antenna may be arranged on either side of a display of the parking meter. Furthermore, the antenna may be arranged on an interior surface of a material sealing an opening in the parking meter housing. A decal may be placed on the covering of the opening to hide the antenna wires while not impeding the transmission of RF signals. Furthermore the individual conductive wires of the antenna of the contactless card reader may be sufficiently small in diameter or fine that even when placed in front of the display they do not significantly interfere with the display visibility, allowing the antenna to be placed over the display. Advantageously, the opening in the metal housing for the display is typically covered with a protective material through which the display is visible, such as Lexan. This material typically provides a low attenuation of RF signals and as such locating the antenna within the opening covered by the low attenuation material provides an improved transmission path, which can increase the likelihood of successfully communicating with a contactless payment device. Furthermore, since the opening is used for viewing the display, and since the display may be used to display a logo, graphic and/or directions such as “tap here”, providing clear and convenient payment instructions to the user, it is not necessary to provide an additional opening in the metal housing of the parking meter, which may improve the strength of the parking meter housing and/or possibly simplifying its construction.
Although various embodiments have been described with different placements of the contactless reader antenna, it is contemplated that the antenna could be located in or on the parking meter in different positions or configurations. The antenna should be placed in sufficiently close proximity to the display, when the parking meter is assembled, to provide an acceptable success rate of reading when a contactless payment device is placed in the vicinity of the display. Arranging the antenna in or on the parking meter in close proximity to the display allows clear instructions to be presented to the user on the display, indicating to the user where to place the contactless payment device. For example, the antenna could be located on an exterior side of the parking meter in close proximity to the display.
Various embodiments of parking meters with contactless payment means have been described. The above-described embodiments of the invention are intended to be examples of the present invention and alterations and modifications may be effected thereto, by those of ordinary skill in the art, without departing from the scope of the invention which is defined solely by the claims appended hereto.
