Some time back LIRNEasia conducted an interesting piece of research on traceability, the concept of being able to trace a food item down to its source in a particular farm. That project involved the use of mobiles to give feedback to farmers, based on numbers assigned to crates of gherkins. We talked about what could be done with barcodes on crates and perhaps barcodes on the fruits themselves, but did not implement. But now it seems that a new barcode that can be read by mobiles is being deployed, with much potential for traceability as well. The new symbols, called GS1 DataBars, can store more data than traditional bar codes, promising new ways for stores to monitor inventory and for customers to save money.
