How to use a passbook equipped with a two-dimensional barcode

Abstract

The invention relates to a using method for a bank deposit book with two-dimensional bar code with the object of overcoming the deficiency in the prior art. The technical solutions are as follows. A two-dimensional bar code scanning device, a two-dimensional deposit book and a two-dimensional deposit book reading and writing device with two-dimensional bar code identifying function are used together. The two-dimensional deposit book reading and writing device is connected to a financial server for communications, including registering procedures, offline check procedures, change procedures, and reading and writing procedures. The registering procedures are executed first; the reading and writing procedures are executed in the need of a user; when the deposit bank is overfilled, the change procedures are executed; the offline check procedures are also executed in the need of the user.
