6 Frequently Asked Questions About Barcode Vs. RFID Scanners

There are many popular questions about barcode and RFID scanners. We are listing the most common ones:

1. Is There A Difference In The Label?

Basically , there is no difference in the information stored in either types when it comes to the consumer. The product features such as price, size, name etc. can be easily stored in an RFID label with the addition of an electronic element. The good thing about this is that this information can be even edited in the RFID tags – making it more efficient and possible to be saved and stored more times. In a nutshell, the two most major benefits of RFID scanners that make them unique are:

• They include a unique code, which makes every RFID label individual and recognized partially and not as a product type.

• The work on radio signals, without any visible contact in order to read the code. This makes reading many codes at a time possible and increases the efficiency without the need to open boxes.

2. Knowing That Every RFID Tag Is Individual, Will My ERP System Store Tens OF Thousands Of New Items?

For example, if a blue T-shirt in size M is understood by the RFID system as code 1234, and the same shirt in size L is understood as 1235. If we look at the stock count for the size M or L therefore, we would search the code 1234 and 1235 to get the count.

However, the RFID technology marks all the blue t-shirts in size M with 1234, but also makes a unique identifier. This means that there can be codes like 1234-1 or 1234-2, all helping the RFID readers to get a grasp of a particular product and how many quantities of a size there are. They are still however decoded to their traditional formed when exported from a database.

3. If The RFID Technology Eliminates The Need For Opening Boxes And Seeing Goods, How Can We Be Sure That All Items Were Really Read?

There is still some knowledge or information of what should be inside of a box. In order to be 100% sure about this, it is advisable to refer to the original document or a document known as an ‘expect list’. The RFID reader would have an expect list which helps it verify the content of the box.

In hectic times such as having several boxes delivered per day, it is impossible to say which box has been read – especially if they are all piled up. However, printed barcodes help the staff in this case – by informing the backend system which individual boxes to be read. The box can be identified and the content will afterwards be scanned against the expect list. This speeds things up and makes them better.

4. Is There A Button That Counts All The Items In My Store?

Yes – that function exists – as a part of the system that automatically follows all the items in a single location. However, using it can be tricky and costly. That is why a combination of fixed and mobile RFID readers is the best way to get the stock count. RFID scanners can count a store very fast, with an average speed of 25 000 items per hour. The traditional barcode scanning, on the other hand, is less effective with about roughly 250 items per hour.

Therefore, we can conclude that RFID count is 100 times faster than the barcode count.

5. Are There Problems With Double-Reading As Seen In Barcodes Where Two Employees Read And Register The Same Items And Therefore Cause Inaccuracy? Can The Automatic RFID Gates Help In This Manner?

The mistake that happens in this case is of human nature – more than it is of technical aspect. Therefore, automatic RFID gates can be used but they are not the best option everywhere.

However, time stamping the reading is possible when RFID tags are read with a mobile or fixed reader. This makes each item unique and lets the system know that the same individual has been seen twice within 10 minutes for example. Also, when it comes to putting items in stock, the individual would be registered only once – regardless of how many readers have seen it. The RFID scanners only verify that an item was really there and ignore its ‘mistaken’ repetition afterwards.

6. What Happens With Retailers Having More Than 50 Stores And Retail Chains? How Much Will Their IT System Need To Change?

Basically, there are solutions for various sized businesses. In most of the cases like this, converting some of the RFID to traditional barcode scanners so that all of the RFID information is offered on a cloud service is by far the best solution. It is also a solution that allows the retailer to get the best out of the RFID technology without redoing the entire IT system immediately. This scenario usually works best for the transition period.
