Barcode Xpress supports the following patch codes:
| Patch Code Type | Barcode Value |
| Patch 1 | 1100 |
| Patch 2 | 1001 |
| Patch 3 | 1010 |
| Patch 4 / Toggle Patch | 0110 |
| Patch 6 | 0011 |
| Patch T / Transfer patch | 0101 |
To write a Patch Code using Barcode Xpress, set the writer BarcodeType property to PatchCode, then set the writer MakeBarcodeValue property to a value of 1 through 6.
Patch Codes require a quiet zone, which should be at least the width of 10 narrow bars. This means that if you set the MakeBarcodeBarSize property to 5 pixels (narrow bar size), you should set the MakeBarcodeBWidth property to 50 pixels. There is no checksum for Patch Code.
