Learn how to fast and easily identify malfunctioning HW or SW in RFID systems with the Photon RF field detector.

RFID is already becoming a mature technology that is constantly producing new innovative products. However, RFID has been in the field for a long period already and there are a number of applications that have been implemented for some years now.

Issues with aging HW

As the RFID HW ages, users are wary of maintaining the performance and how to detect any issues – such as decreased read range that harms the system objective.

Photon tags help users and/or maintenance staff check if the HW in place is performing properly in a fast and easy way.

The Photon will light up its LED as soon as it has enough energy to power it up. This is used in maintenance tasks to assess the condition of the system. It makes sense to establish a ‘Photon range’ – distance at which the LED will shine – when installing the system so that maintenance staff have it as a reference for future assessment.

The Photon is also very interesting for RFID system FW and SW development. When developing SW and making changes to that SW and the system fails to perform, there’s always an uncertainty of what can be the cause for it.

The Photon is a very fast way of assessing if the reader is actually transmitting or not, as the integrated LED will light up if it is. You will also have the idea of the approximate duty cycle of power transmission (read a previous post about duty cycle when programing for RFID sensor tags here) since the LED will switch from ON to OFF and back to ON as soon as there is power (or there is not, for the OFF mode).

Take advantage of simple RF field detectors to visually identify the field intensity and duty cycle. A fast and easy assessment of what the RF field is and its behavior will save you lots of resources.
