The interface receives a barcode display instruction. The processor generates a basic barcode in response to the display instruction received by the interface, generates a plurality of barcodes in which noise is superimposed at different positions on the basic barcode, determines whether there is misreading in an image scanned by a barcode reader on a screen on which the plurality of barcodes are sequentially displayed, and sequentially displays the plurality of barcodes on a display device when it is determined that there is no misreading. ## Claims ### Claim 1 A barcode generation device, comprising: an interface configured to receive a barcode display instruction; and a processor configured to generate a basic barcode in response to the barcode display instruction received by the interface, generate a plurality of barcodes in which noise is superimposed at different positions on the basic barcode, determine whether there is a misreading in an image scanned by a barcode reader on a screen on which the plurality of barcodes are sequentially displayed, and sequentially display the plurality of barcodes on a display device when a determination indicates that there is no misreading. ### Claim 2 (depends on 1) The device according to claim 1, wherein to determine whether there is the misreading comprises to determine whether there is misreading in each of images of a plurality of barcodes in which the noise is superimposed, and to determine whether there is misreading in a combined image which is obtained when the plurality of sequentially displayed barcodes are scanned. ### Claim 3 (depends on 1) The device according to claim 1, wherein the basic barcode is generated so as to be decodable by a barcode reader. ### Claim 4 (depends on 1) The device according to claim 1, wherein the plurality of barcodes is generated so as to be undecodable by a barcode reader. ### Claim 5 (depends on 1) The device according to claim 1, wherein the display device is a smartphone. ### Claim 6 A barcode generation device, comprising: an interface configured to receive a barcode display instruction; and a processor configured to generate a basic barcode in response to the barcode display instruction received by the interface, generate a split barcode image group in which the basic barcode is split into a plurality of images that are singly undecodable, and sequentially display the split barcode image group on a display device. ### Claim 7 (depends on 6) The device according to claim 6, wherein the split barcode image group comprises an image group in which the basic barcode is split so that partial regions overlap between adjacent regions. ### Claim 8 (depends on 6) The device according to claim 6, wherein the basic barcode is generated so as to be decodable by a barcode reader. ### Claim 9 (depends on 6) The device according to claim 6, wherein the split barcode image group is generated so as to be undecodable by a barcode reader. ### Claim 10 (depends on 6) The device according to claim 6, wherein the display device is a smartphone. ### Claim 11 A barcode generation method, comprising: generating, by a processor, a basic barcode in response to a barcode display instruction received; generating, by a processor, a plurality of barcodes in which noise is superimposed at different positions on the basic barcode; determining, by a processor, whether there is a misreading in an image scanned by a barcode reader on a screen on which the plurality of barcodes are sequentially displayed; and sequentially displaying the plurality of barcodes on a display device when a determination indicates that there is no misreading. ### Claim 12 (depends on 11) The barcode generation method according to claim 11, further comprising: determining, by a processor, whether there is a misreading in each of images of a plurality of barcodes in which the noise is superimposed, and determining, by a processor, whether there is a misreading in a combined image which is obtained when the plurality of sequentially displayed barcodes are scanned. ### Claim 13 (depends on 11) The barcode generation method according to claim 11, wherein the basic barcode is generated so as to be decodable by a barcode reader. ### Claim 14 (depends on 11) The barcode generation method according to claim 11, wherein the plurality of barcodes is generated so as to be undecodable by a barcode reader. ### Claim 15 (depends on 11) The barcode generation method according to claim 11, wherein the display device is a smartphone. ### Claim 16 A barcode generation method, comprising: generating, by a processor, a basic barcode in response to a barcode display instruction; generating, by a processor, a split barcode image group in which the basic barcode is split into a plurality of images that are singly undecodable; and sequentially display the split barcode image group on a display device. ### Claim 17 (depends on 16) The barcode generation method according to claim 16, wherein the split barcode image group comprises an image group in which the basic barcode is split so that partial regions overlap between adjacent regions. ### Claim 18 (depends on 16) The barcode generation method according to claim 16, wherein the basic barcode is generated so as to be decodable by a barcode reader. ### Claim 19 (depends on 16) The barcode generation method according to claim 16, wherein the split barcode image group is generated so as to be undecodable by a barcode reader. ### Claim 20 (depends on 16) The barcode generation method according to claim 16, wherein the display device is a smartphone.
