System for controlling user access to a service

摘要

A system for controlling user access to a service includes a read device that reads a payment card of a user, and a first control block coupled an entry gate determines whether online payment authorization should be requested for the payment card. A first memory stores a hot list indicating payment cards for which the first control block denies user access to the service. If the online payment authorization is denied for the payment card, the first control block adds the payment card to the hot list. A further read device is configured to read the payment card, and a second control block coupled to the further read device controls a second gate after determining whether the payment card is on the hot list stored in a second memory coupled to the second control block, the hot list being updated with modifications via a network.

主权项

1. A system for controlling user access to a service comprising:
a read device configured to read a payment card of a user; a first control block coupled to the read device and an entry gate, the first control block being configured to
determine whether online payment authorization should be requested for said payment card, wherein in response to a determination that the online payment authorization should be requested, the first control block is further configured to request an offline payment authorization, and determine that the online payment authorization should be requested in response to denial of the offline payment authorization, and wherein for the online payment authorization the first control block is further configured to make an online payment authorization request and to control the entry gate to allow said user access to the service prior to completing said online payment authorization for said payment card; a first memory coupled to said first control block and comprising a memory portion storing a hot list indicating payment cards for which the first control block denies user access to the service, wherein said first control block is configured to add said payment card to said hot list in response to a determination that the online payment authorization is denied for that payment card; a further read device configured to read said payment card; a second control block coupled to the further read device and configured to control a second gate; and a second memory coupled to the second control block and comprising a memory portion storing the hot list, wherein the hot list is updated with modifications via a network and wherein the second control block, after the further read device reads the payment card, controls the second gate after determining whether the payment card is on the hot list stored in memory.
