Abstract
Abstract A system for providing items of value, charging the items to a smart card, and for recharging the smart card. The system includes a station (30) for providing the items of value, which may be postal services, and debiting the cost of the items to a smart card; the smart card being charged with funds equivalent data. The station also communicates with a Data Center (10) for recharging the smart card. Users of the system communicate with the data center to request recharge of a particular smart card and in response to an authorization request the data center generates an encrypted authorization message which includes an identification number, the amount of recharge requested, and control data, which preferably includes a control sum formed by adding the amounts stored in a descending register, which stores the amount available on the smart card, and an ascending register which stores the total of the amounts by which the card has been charged since initialization. Thus, the authorization message may be used only once. From time-to-time the Data Center (10) transmits authorization messages to each station (30) on the system. When a particular smart card for which an authorization message has been received is connected to a station (30), the smart card compares the control data with the control data stored on the smart card and if there is a match updates the funds equivalent data in the descending register of the smart card. To provide security against transmission of false authorization messages to a station, the authorization messages are encrypted, preferably using a public key encryption system.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
154 words
A system for providing items of value, comprising a) a station for providing said items of value and debiting the cost of said items of value to a smart card charged with funds equivalent data, and for recharging said smart card, said station further comprising: a1) a controller; a2) a smart card reader operatively connected to said controller; a3) input means for input of control signals to said controller controlling provision of said items of value; and a4) providing means, responsive to said controller, for dispensing said items of value; b) data processing means for generating an authorization signal unique to a particular smart card; c) communications means for connecting said station and said data processing means for transmitting said unique authorization signal to said station; and d) said station being responsive to reception of said authorization signal and connection of said particular smart card to said card reader to recharge said smart card.
Claim 2
Dependent Claim
20 words
A system as claimed in claim 1, wherein said operation of providing items of value comprises franking of mail pieces.
Claim 3
Dependent Claim
62 words
A system as claimed in claim 1 or 2 further comprising at least one further said station, wherein, from time-to-time, said data processing means transmits a plurality of said authorization signals to each of said stations, through said communications means, and, wherein said authorization signals are one-time signals which can only be used to recharge said particular smart card a single time.
Claim 4
Independent Claim
16 words
A system as claimed in any preceding claim, wherein said authorization signal comprises an encrypted message.
Claim 5
Dependent Claim
25 words
A system as claimed in claim 4, wherein said encrypted message comprises control data relating to said particular card for identifying said particular smart card.
Claim 6
Dependent Claim
15 words
A system as claimed in claim 5, wherein said control data comprises a control sum.
Claim 7
Dependent Claim

A system as claimed in claim 4, wherein said message is encrypted using the private key of a public key encryption system and decrypted by said smart card using the public key of said encryption system, whereby compromise of said smart card will not provide the capability to generate said encrypted message.
Claim 8
Independent Claim
82 words
A system as claimed in any preceding claim further comprising at least one further said station, wherein, from time-to-time, said processing means transmits a plurality of said authorization signals to each of said stations through said communications means; each of said stations storing said plurality of authorization signals and, upon connection of one of said particular smart card corresponding to one of said stored authorization signals recharging said corresponding particular smart card and deleting the corresponding one of said stored authorization signals.
