Reference will now be made, by way of example only, to the accompanying drawings, in which:
Embodiments of the present invention provide improved payment card holders which include an alarm system for alerting the user of the card holder to the absence of the card concerned. Although the cards are referred to in the present description as payment cards, which include credit and debit cards, it will be readily appreciated that the present invention is applicable to any type of card, such as an identity card or driving licence, which one would usually carry in a wallet or purse.
The system includes detection devices 12a and 12b that are connected to supply respective detection signals to the microprocessor 10, as will be explained in more detail below. It will be readily appreciated that any number of detection devices may be provided, and that the two illustrated in
The microprocessor 10 is connected to supply a driver signal to an audio coder/decoder (codec) 18, which, in turn, supplies an audio signal to a loudspeaker 19. In addition, the microprocessor controls an LED (light emitting diode) driver 20 which itself outputs an LED driver signal to a LED 21.
An interface 22 is provided for connecting a microprocessor 10 to a suitable programming device such as a personal digital assistant (PDA) or personal computer (PC). The interface device is preferably provided by a universal serial bus (USB) connection, but could be provided by any suitable interface device.
A battery 24 provides power for the alarm system, which is preferably a lithium ion (LION) battery. The battery is charged by a charger 26, which, in the embodiment shown in
An RFID (Radio Frequency Identification) tag 30 is provided in order to identify the alarm system to an external RFID reader. A snooze button 32 is provided in order to temporarily disable the alarm system.
Operation of the system embodying the present invention will now be described with reference to
In a preferred embodiment of the present invention, the microprocessor operates to store an audio data file in the memory device 16 for retrieval when outputting an alarm condition. For example, the audio data file could be an MP3 audio file or any suitable encoded audio file. The audio file is preferably supplied to the microprocessor and memory device via the interface device 22 from a suitable programming device, such as a PDA or PC. In this way, it is possible for the user to program and supply their own alarm signal in a manner akin to providing a ring tone on a mobile telephone.
The microprocessor 10 can also be programmed to set parameters for an alarm condition being triggered. The most significant parameter is the amount of time that must elapse before the alarm is triggered. Using a suitable programming device such as a PDA or PC that communicates with the microprocessor via the interface device 22, the user is able to set this time period.
The alarm system embodying the present invention can be applied to any bag, wallet or purse, but is particularly suited for providing an alarm system for payment card holders. In particular, it is envisaged that the embodiment shown in
The provision of an RFID tag 30 in embodiments of the present invention, enables owner information of the payment card holder to be stored securely within the holder itself. The RFID tag can be used to supply that information to a suitable RFID reader, which aids identification of the owner.
It will be readily appreciated that embodiments of the present invention provide significantly improved alarm systems for payment card holders, by allowing a user to program the alarm signal, the conditions for creating an alarm signal, and for providing additional security measures, particularly in the example of a payment card holder having a hard case.
