<p>An improved sensing apparatus is provided for reading coded embossments on a credit card which represent the account number thereof, or other data. The apparatus is for use in a credit verification system. The sensing apparatus of the invention forms a component of the sales slip imprinter mechanism which is presently used in conjunction with credit card transactions, in order to provide a record of the transaction for billing purposes. The sensing apparatus of the invention includes a multiplicity of pneumatically actuated diaphragm switches which are operated in a pattern corresponding to the coded embossments on the credit card being sensed. The switches make selective electrical contact with a circuit board, and they cause binary coded decimal signals to be stored in a register which represent the account number of the card, or other relevant data, the signals being used in the system to verify the validity of the particular card; or for accounting purposes, or for storage of data for later use.</p> |
