1D barcodes are classic. They are found everywhere from the grocery store to the electronics you buy online, and are very standardized. 1D barcodes are simple and easy to use, but the drawback is they are very limited in the amount of data they can hold. With new advancements in barcode technology, the future of 1D barcodes remains uncertain. The major issue is they only can contain numbers and no extra data. This works well for basic categorization of data by cross-referencing numbers in a lookup table, however if you are looking for anything extra you won’t be able to add it into a 1D barcode. Also, with new items to market going with 2D or NFC barcodes, you may have to re-vamp your system in the near future.
