How to Set Up Multiple RFID Readers in Close Range

Using multiple radio-frequency identification (RFID) readers in a relatively confined space can be a tricky proposition. We tell our customers that if they want to have multiple readers in their application that they should space them at least 1 meter apart. That is quite a significant distance, and in some cases, it isn’t practical.
