1D bar code

A one-dimensional bar code only expresses information in one direction (usually in the horizontal direction), but does not express any information in the vertical direction, and its certain height is usually to facilitate the alignment of the reader.

The application of one-dimensional barcodes can increase the speed of information entry and reduce the error rate, but there are also some inadequacies in one-dimensional barcodes:

* Smaller data capacity: about 30 characters

* can only contain letters and numbers

* Relatively large bar code size (low space utilization)

* The barcode cannot be read after it has been damaged
