Just to clarify for yourself and others, as it is a self-perpetuating misnomer on here. It’s easy to get confused and people will know what you mean when you say it, BUT better to “nip it in the bud”
RFID is any Radio-frequency Identification system regardless of the actual frequency.
So
Low Frequency ( LF ) 125 kHz eg. xEM uses RFID to communicate
AND
High Frequency ( HF ) 13.56 MHz eg. xNT uses RFID to communicate
an asset tracking system using 900MHz stickers is also using RFID to communicate
NFC Near-field communication is just a communication protocol it uses, Which operates using RFID in the HF band of 13.56MHz and that is how your phone can communicate with the NExT (xNT)
I will put an “understanding terminology” or a Glossary in the Beginners Guide Wiki just to clarify for people, There are a lot of acronyms and initialisms that cause a lot of confusion.
All that being said, Good choice on the NExT and sounds promising for your work access HID 125kHz.
Your NExT will be in EM mode but I ???THINK??? HID will require T5577, which it is capable of… but we’ll deal with that when / if we have to.
Keep us in the loop, I hope your installer gets back to you.
