ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a Smart Card which is a card similar in size and feel to a credit card and which is capable of storing information in an integrated microprocessor chip located within the body of the card.
2. Background of the Invention
An integrated micro-processor chip may hold a variety of different information, for example monetary value used for retail and vending machines, secure information and applications relating to medical or health care records. Furthermore such cards may be used in a new category of mobile phone known as Dual Smart Card Phone which enables consumers to access an almost limitless range of services such as mobile electronic ATM facilities, remote ticketing, pre-paid mobile communications, and secure on-line payment mechanisms via the cellular telephone handset.
Using such a Dual Smart Card Phone users will, it is envisaged, be able to download electronic cash onto the Smart Card which will eliminate the inconvenience and potential hazards associated with travelling to a bank cash machine to access electronic funds or to make account transactions.
Users will also be able to use such a phone to pre-pay for air time as the air time is used, utilising cash debited from the Smart Card. Such a system has the advantage to service providers by maintaining low revenue customers on their billing systems and users avoid the risk of long-term service agreements. By pre-paying, users can switch services at will and are not hindered by a low credit rating. Pre-paying also renders possible hardware or software upgrades at any time and time may be booked from a local service provider instead of being charged a fee to roam.
Smart Cards may be also used for ticketing on public transport and leisure services.
The number of Smart Cards in circulation is growing at the rate of 30% per annum and the number of Smart Cards in circulation over the next five years is expected to increase to 3.85 billion, accounting for card sales of US$5 billion.
Smart Cards currently being used are contact, contactless or combination cards. Contact Smart Cards must be inserted into a Smart Card reader and have a contact plate on the face of the card which forms an electrical contact for reading from the chip or writing to the chip when the card is inserted into the reader.
Contactless Smart Cards have an antenna coil, as well as a chip embedded within the card. The internal antenna permits communication with a receiving antenna at the transaction point to facilitate transferal of information. Close proximity is required for such transactions which can decrease transaction time while increasing convenience.
A combination card functions as both a contact and contactless Smart Card.
Such Smart Cards often contain information which the user wishes to prevent access to by third parties. Hence, once the Smart Card has completed it's useful life it is often necessary to destroy the Smart Card to prevent it from being used by third parties. The customary manner of destroying such a Smart Card is, like a conventional credit card, to cut it into two or more portions such that the chip is destroyed.
The present invention seeks to provide a Smart Card which is more readily destroyed.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described, by way of example, with reference to the accompanying drawing, which shows, in schematic form, a Smart Card in accordance with this invention.
