  If your Cansec Card Reader isn't recognizing cards or tags, there could be several reasons. First, power down the reader and access panel, and then check the wiring to ensure it's correct. Also, measure the voltage at the reader; it should be between +5 VDC and +14 VDC. The issue might also be due to electromagnetic interference, so try moving the reader away from other electronic devices. Finally, ensure you are using a card that is compatible with the reader.

  A short read range on your Cansec Card Reader can stem from a few potential issues. Check the shield line for open connections and ensure it's properly connected to the access panel. Another cause might be electromagnetic interference; try relocating the reader away from other electronic devices. Also, the power supply on the access panel must be a regulated, linear supply because switching supplies are often sources of electromagnetic interference.
