Abstract

Abstract A point-of-sale credit card verifier (1) for checking the validity of cards, such as credit cards, comprises means for non-destructively storing information (3) on invalid credit cards for comparison with information which is read from a card presented for use. The information on invalid credit cards is transmitted by signals embedded in a VHF stereo radio broadcast from a broadcast station which is received by a VHF receiver/demodulator (10). A credit card sensor (4) and control maintains the verifier switched off unless a credit card is to be read. The verifier is switched on when information is about to be broadcast from a broadcast station. The verifier operates quickly and independently of telecommunications networks.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 65 words
A credit card verifier comprising: a radio signal receiver froming reception means for receiving information on invalid cards from a central control station; memory means for storing the information received as stored data; reading means for reading encoded data on the card; comparison means for comparing the encoded data and the stored data; and output means for delivering a signal in response to said comparison.
Claim 2
Dependent Claim 65 words
A credit card verifier comprising: a radio signal receiver froming reception means for receiving information on invalid cards from a central control station; memory means for storing the information received as stored data; reading means for reading encoded data on the card; comparison means for comparing the encoded data and the stored data; and output means for delivering a signal in response to said comparison.
Claim 3
Dependent Claim 19 words
A credit card verifier as claimed in claim 1 in which the radio signal receiver is a VHF receiver/demodulator.
Claim 4
Dependent Claim 33 words
A credit verifier as claimed in claims 1 or 2, including a keyboard and associated equipment for inputting information and transaction data into the verifier and means for storing the said transaction data.
Claim 5
Dependent Claim 25 words
A credit card verifier as claimed in claim 3 in which means are provided for sending the said transaction data to the central control station.
Claim 6
Dependent Claim 21 words
A credit card verifier as claimed in claims 3 or 4 in which a printer is provided for the transaction data.
Claim 7
Independent Claim 59 words
A method for verifying a credit card comprising the steps and sequence of: receiving an information radio signal from a central control station; storing the information received as stored data; inserting a card into the verifier; reading encoded data on the card; comparing the stored and encoded data; and rejecting or accepting the card in response to the comparison.
Claim 8
Independent Claim 59 words
A method for verifying a credit card comprising the steps and sequence of: receiving an information radio signal from a central control station; storing the information received as stored data; inserting a card into the verifier; reading encoded data on the card; comparing the stored and encoded data; and rejecting or accepting the card in response to the comparison.
Claim 9
Dependent Claim 62 words
A method of verifying a credit card as claimed in claim 6 comprising the additional steps of: receiving a preparatory radio signal; activating input circuitry for a signal storage device, a pre-set time after the preparatory radio signal; and after receiving the information radio signal and storing the information received as stored data, de­activating the input circuitry of the signal storage device.
