In U.S. patent application Ser. No. 12/356,367, filed Jan. 20, 2009 (and incorporated herein by reference), the present inventor disclosed a technique for securing a small contactless payment card to a mobile telephone. According to this technique, a protective case for the mobile telephone includes a slot or pocket into which the contactless payment card is inserted, at a time when the mobile telephone also has been installed in the case. As is well known, contactless payment cards allow account holders to access debit or credit card accounts to pay for transactions by wireless communication between the contactless payment cards and proximity readers included in point of sale (POS) terminals. When a contactless payment card is secured to the mobile telephone by a protective case as described in the '367 patent application, payment for a transaction may be effected by tapping the mobile telephone on the POS proximity reader.
The technique described in the '367 patent application provides a number of advantages, particularly in view of the small form factors for mobile telephones that have generally prevailed in recent years. However, with the advent and widespread adoption of the “iPhone” mobile smart phone (sold by Apple, Inc.) it may now be desirable to adapt the technique of the '367 patent application to securing an ID-1 contactless payment card to the iPhone or similar devices. This modification of the teachings of the '367 patent application may be desirable because an ID-1 card, unlike the small contactless payment card shown in the '367 patent application, may include a magnetic stripe, and thus may be usable with POS magnetic stripe readers as well as proximity readers. This modification of the teachings of the '367 patent application is feasible because the substantially 4.5 inch by 2.4 inch form factor—and planar rear surface—of the iPhone would readily accommodate the ID-1 form factor (substantially 3.37 inches by 2.125 inches).
However, the present inventor has recognized a potential problem with this proposed modification of the teachings of the '367 patent application, a problem not recognized in the prior art. According to this potential problem, if a conventionally configured ID-1 contactless payment card were secured via a mobile phone case to an iPhone, the result may be that a portion of the antenna of the payment card may overlie the antenna of the iPhone, thereby potentially interfering with proper functioning of the iPhone and/or adversely affecting the SAR (Specific Absorption Rate) of the iPhone, and thus possibly giving rise to safety concerns as well as performance issues for the phone.
Features and advantages of some embodiments of the present invention, and the manner in which the same are accomplished, will become more readily apparent upon consideration of the following detailed description of the invention taken in conjunction with the accompanying drawings, which illustrate preferred and exemplary embodiments and which are not necessarily drawn to scale, wherein:
In general, and for the purpose of introducing concepts of embodiments of the present invention, the antenna component of an ID-1-sized contactless payment card is configured so as to be about one inch distant from the right-hand edge of the card. With this antenna configuration, the card may be inserted into a slot of a protective case for an iPhone or similar device, without resulting in interference by the card antenna with functional characteristics of the iPhone.
The mobile telephone 100 may be entirely conventional, and may, for example, be the widely-used iPhone mobile smart phone, as mentioned above. As is well known, the iPhone includes a relatively large touch screen, an operating system that supports numerous applications (“apps”) and a telephone antenna (hidden within the body of the phone) by which voice and data signals are transmitted to and from the phone.
The contactless identification card 102 may, for example, be a credit card or debit card, and/or may identify the individual who holds the card for purposes other than or in addition to payment. For example, the card may be a transit system access card, a retail customer loyalty card, a gym membership card, a building or office suite access card, etc. However, for the most part hereinafter the card 102 will be referred to as “contactless payment card 102”. Details of the contactless payment card 102 will be provided below.
In accordance with an aspect of the present invention, the mechanism that secures the contactless payment card 102 to the mobile telephone 100 may be an article of manufacture such as a protective carrying case 104 for the mobile telephone 100. In some ways the protective case 104 may be conventional, and may for example generally resemble an item such as the “Elan Form Chrome” carrying case, available from Griffin Technology, Nashville, Tenn. The protective case 104 may, for example, generally form a pouch 106 that is shaped and sized to receive the mobile telephone 100. It will be appreciated that the pouch 106 may serve as a mechanism that secures the protective case 104 to the mobile telephone 100 and vice versa.
In accordance with aspects of the present invention, the protective case 104 may include a slot or pocket 108 which is schematically shown in the drawing (and which is an additional feature not present, e.g., in the above-mentioned Elan Form Chrome protective case). The slot is defined by full and/or partial sheets of material from which the protective case 104 is formed, those sheets of material thus constituting a mechanism for defining the slot 108. The slot 108 is shaped and sized to receive and securely hold the contactless payment card 102. It will be understood that the manner of the contactless payment card 102 being “securely held” in the slot 108 may be a consequence of frictional forces resulting from a fairly snug fit of the contactless payment card 102 inside the slot 108. By the same token, if the user (not shown) were to grip an edge of the contactless payment card 102 at the opening 110 of the slot 108, the user may be able to readily withdraw the contactless payment card 102 from the slot 108.
(In the illustration presented in
According to an aspect of the invention, the contactless payment card 102 may be in the familiar ID-1 form factor.
The contactless payment card 102 includes a card-shaped body 202 (e.g., laminated from layers of plastic) in the ID-1 form factor. The plastic card body 202 has a left edge 204, a right edge 206, a top edge 208 and a bottom edge 210. (To define the term “right edge” in more detail, that term refers to the right-hand side edge of the payment card as the front-surface of the payment card is viewed with printing on the front-surface oriented for normal reading (i.e., with the printing “right-side up”).) In its appearance, the front surface of the contactless payment card 102 may resemble conventional payment cards, and may display a payment card account number presented in embossed numerals 212. The contactless payment card 102 may also display, on its front surface, the cardholder's name 214, the name 216 of the issuing bank, the brand 218 of the authorizing payment card system (in this case “MasterCard”, indicating that the contactless payment card 102 is issued under the authority of MasterCard International Incorporated, the assignee hereof), and the payment card system logo 220. In addition, in accordance with an aspect of the present invention, the front surface of the contactless payment card 102 may display a legend or logo 222 that is indicative that the contactless payment card 102 is configured such as to avoid interference with operation/functional characteristics of the mobile telephone 100. Details of such configuration of the contactless payment card 102 will be described below in conjunction with
The front surface of the contactless payment card 102 may present additional information which is not shown in the drawing, such as the card expiration date.
The antenna 304 is coupled to the RFID chip 302 to allow the RFID chip 302 to receive interrogation signals from proximity reader devices included in POS terminals. The antenna 304 also allows the RFID chip 302 to transmit payment card account information and other information to the POS terminals. It will be appreciated that the RFID chip may store, in the form of digital data, the payment card account number displayed on the front surface of the contactless payment card 102. The contactless payment card 102 may operate in accordance with conventional practices. For purposes of illustration, the RFID chip and antenna are shown in
In accordance with conventional practice, the rear surface of the contactless payment card 102 carries a magnetic stripe 402 which extends from one side edge of the card body towards the opposite side edge, except that the magnetic stripe 402—in accordance with an aspect of the present invention—stops short of the above-mentioned keep-out zone 306, instead of extending all the way across the width of the plastic card body 202, as do conventionally configured magnetic stripes for payment cards. The purpose of this reduced configuration of the magnetic stripe 402 is again (like the configuration of the card antenna) to reduce or prevent interference with the operation/functional characteristics of the mobile telephone 100 when the contactless payment card 102 is secured to the mobile telephone 100 in the manner illustrated in
Continuing to refer to
The magnetic stripe 402 may store the same payment card account number stored in the RFID chip 302 and displayed on the front surface of the contactless payment card 102. The magnetic stripe 402 may be configured to allow conventional magnetic stripe reader components of POS terminals to read the payment card account number and other information from the magnetic stripe 402.
(The rear surface of the payment card may also include conventional features that are not indicated in
At 702 in
At 704, the user inserts a contactless payment card, such as the contactless payment card 102 described above, into the slot 108 in the protective case that holds the mobile telephone 100. In this way the payment card is removably secured to the mobile telephone, bringing about the condition schematically illustrated in
At 706, the user takes the mobile telephone, bearing the protective case and the contactless payment card, with him/her while he/she visits a retail store. At 708, the user makes a selection of merchandise at the store and presents the merchandise for purchase at a POS terminal in the store. After the sales clerk has entered the items to be purchased into the POS terminal (e.g., by scanning barcodes on the merchandise), the user effects payment for the transaction. This may be done when the user taps (step 710) the mobile telephone (e.g., with the payment card side down) on the proximity reader component of the POS terminal. With the payment card thus or otherwise brought into proximity with the reader, wireless communications are exchanged between the payment card and the reader. In this manner, the user's payment card account number is communicated from the contactless payment card to the POS terminal and used to authorize and settle the purchase transaction.
The mobile telephone 100 contains a battery (not separately shown) or other components that may tend to short out the antenna of the contactless payment card 102 and thus may tend to interfere with the operation of the contactless payment card 102. To aid in addressing this issue, and as illustrated by item 112 in
In the foregoing description, it was assumed that the magnetic stripe and the RFID chip both stored the same payment card account number, namely the PAN (primary account number) shown on the front surface of the contactless payment card 102. However, in some embodiments, whilst the magnetic stripe stores the PAN, the RFID chip may instead store a special or proxy payment card account number to be used only for contactless payment transactions (in accordance with teachings of U.S. published patent application no. 2008/0306850). It will be appreciated that the PAN stored in the magnetic stripe is used for transactions in which the magnetic stripe is “swiped” through a magnetic stripe reader component of a POS terminal; such transactions may be considered to be “swipe transactions”.
Up to this point, the invention has been discussed in terms of contactless payment cards. Alternatively, however, the principles of the invention may be applied to other types of contactless identification cards, such as those used to permit access to a transit system, or those used to identify participants in a customer loyalty system.
In some embodiments, the card antenna may also be configured to be distant from the left edge of the payment card by about one inch or more, to allow for the payment card to be inserted into the mobile phone case slot with its left edge leading rather than with its right edge leading.
