April 19, Supply Chain Comment: I say "infamous" because not long after the announcement of the program to tag cases and pallets in June of at a meeting of the VICS retail data standards organization now part of GS1the controversy began. What do you say? Click here to send us your comments Walmart vendors were concerned about the costs of RFID tags and the physical application to the cases, which would have to be done in their distribution centers.

These devices can be large pieces of hardware the size of a small book, such as those attached to ocean containers, or they can be very small devices inserted into a label on a package commonly known as smart labels.
A little RFID vocabulary: Active tags are RFID tags that contain their own power source battery and have longer read ranges. Passive tags are powered by the signal generated from the reader device. Read only tags are programmed once and their data cannot be changed.
EPC electronic product code is a set of standards designed to utilize RFID technology for the tracking of individual items, as well as cases and pallets.
Smartlabels are labels with integrated RFID chips. The idea is that you would continue to produce labels probably with bar codes as you currently do, but you would also be programming the RFID chip embedded in the label.
This would provide all current functionality human and machine readable text and bar codes as well as adding RFID functionality. Slap-and-ship describes an approach to complying with customer requirements for physical identification of shipped goods. Most recently, slap-an-ship has been used to describe complying with RFID requirements such as those from Wal-Marthowever, it is also applicable to any compliance labeling requirement such as compliance bar code labels.
Slap-and-ship implies you are meeting the customer's requirement by applying the bar code labels or RFID tags, but are not utilizing the technology internally.
Comparisons to Bar Codes. RFID technology does not require line-of-sight reading. Unlike a bar code, an RFID tag can be read through other materials though some materials may cause problems.
Theoretically, this means that you could take a pallet of mixed products, all of which contain individual RFID tags, and have an RFID reader read all the tags within the palletized load without having to physically move any of the materials or open any cases.
RFID tags can hold more data than bar codes. As the data storage capacity of RFID tags increase, so does the cost of the tags. Therefore, you will likely find that many RFID tags will not hold any more data than a bar code.
RFID tag data can be changed or added to as a tag passes through specific operations. Therefore, you will likely see limited use of this functionality. RFID tags are more effective in harsh environments where bar code labels have problems. RFID tags can be sealed within a plastic enclosure eliminating many of the problems that plague bar codes in harsh environments where they are exposed to chemicals, heat, abrasion, dirt and grease buildup, etc.
A large number of RFID tags can be read almost instantaneously.
This brings us back to the palletized load scenario where the load contains a large quantity of products, each with its own RFID tag. Though it may seem as though the tags are all read at once, they are actually read sequentially one at a timehowever, this happens so fast that it is virtually imperceptible.
This is the biggest hurdle to RFID tags replacing bar codes for item-level tracking of low-cost products. And even if we get 5-cent tags, that is still a significant cost to add to the manufactured cost of low-cost consumer goods.
And even with higher-cost products, or case and pallet level tracking, the benefits of RFID must be greater than this additional cost. RFID signals may have problems with some materials. Metals and liquids can cause problems when trying to read RFID tags.
Tag placement is becoming a science in and of itself since — depending on the product — even a case-level RFID tag may have to be placed in a specific location on the case and cases stacked in a specific orientation to get a consistent read.Walmart is also in the process of rolling out Walmart Pay, a mobile payment feature in its app that is intended to foster loyalty and speed up the checkout process, addressing a major complaint in.
