The choice between fixed vs. handheld RFID readers is not always crystal clear. When investing in RFID technology in a retail setting, the most important thing is to choose the right device for your use case. That’s why Nordic ID RFID solutions are designed to fit existing, specific use cases, and not just as catch-all tools. For example, the same fixed RFID reader could be installed onto a wall or onto a trolley on wheels. Both are fixed readers by definition, but the other is still movable, and more suitable for smaller spaces.
RFID can be used throughout your retail brand’s entire value chain. In this article, our aim is to give you guidelines on a couple of use cases in which the choice between hand-held and fixed readers is especially relevant. These are:
Reading items during transport is not always necessary. Companies often rely on reading items at the following points:
However, if the parcel moves from one vendor to another before arriving at the store, and if there is a reason to worry about shrinkage during transport, adding reading points will make sense. In the case of transport, the reading points should be mobile, so they can be moved from one vehicle to another and used wherever needed.
The main challenge for the use of handheld or wearable reading devices in transport vehicles is accessing the central database from the RFID device. Should the mobile unit save all information to its permanent memory and only update data when placed in the cradle? Or should all information be online, all the time?
During transport, the upload and download of information will have to rely on mobile phone networks; typically, 3G, 4G, or Wi-Fi. Most available mobile devices have methods of handling data transmission over these networks, but you should plan around probable blind spots. The best units, for example, make sure the data is safe even when the network connection is down. However, different operating systems and device manufacturers have different methods for this. Therefore, it is important to choose an application for a mobile device that supports data security. Secured access to the database should carry no extra cost, no matter the device.
In general, all-in-one readers – handheld devices with integrated RFID readers – usually offer better performance than a mobile phone in combination with an external RFID reader enhancement.
Most RFID users combine handheld and fixed readers on the shop floor. Next, we’ll go over
Choosing handhelds or fixed readers depends on the process. When just re-writing information on existing tags, it is possible to use handheld devices to take care of the tag updates. When there is a regular need to create new tags, it might be more efficient to have a separate printer in the store. Typically, both the PoS application and handheld devices allow items to be re-tagged.
Your specific use case, environment, and goals are the most important factors to consider when choosing between fixed or handheld solutions. Oftentimes, fixed and handheld readers are best used in parallel. The following are typical use cases in which you would initially lean towards one or the other as a starting point.
Handheld devices are best suited for use cases where staff moves around on the shop floor and/or the tagged item could be anywhere in a specific area. Such applications are:
When RFID reading (and writing) always takes place in the same area, a fixed reader is a good choice. Such operations are:
