What was difficult with developing these new features was the fact that we have to deal with not just SKUs but a level deeper with serial numbers. The problem that this creates is that if we simply added an “Expiration Date” field to the product information, if you printed items with one expiration date and then went into the product information and changed the expiration date and printed more tags with the new expiration date it would change the expiration dates for the tags that were previously printed. The same issue applies to the “Cost” and “Lot Numbers”. This is why we set it up so that you enter the expiration dates, lot number, and costs in the printing process and not in the product information.
An expiration date using RFID is much different from an expiration date that is printed on a simple tag. While the process may seem simple, it is actually more complicated with RFID than simply printing the dates on a tag and the result is much more robust.
The obvious benefit to having the expiration dates encoded in the tags as opposed to just printed on the face of a tag is that you can gather the expiration dates of your product wirelessly. This will then allow you to quickly know if you have any items that are going to expire soon and get rid of them.
