FAQ: 125kHz vs 13.56MHz access control theihna tur credentials
Q: 13.56MHz hi 125kHz aiin a him zawk fo em?
A: No. 13.56MHz hi system-in MIFARE Plus SL3 emaw DESFire EV2/EV3 ang chi chip hmanga encrypted authentication a hman hian a him zawk thei hle. Mahse reader chuan unencrypted card serial number chauh a check chuan system chu low-security ID token angin a la awm thei tho.
Q: Reader thlak danglam lovin 125kHz Keyfobs hi DESFire Keyfob hmangin ka thlak thei ang em?
A: A tlangpuiin ni lo. Reader awm tawhte chuan 125kHz proximity ID chauh an support a nih chuan DESFire credentials an chhiar thei lo va, an authenticate thei lo bawk. 13.56MHz ISO14443A-capable reader leh encrypted data mamawh handle thei tur access software i mamawh a ni.
Q: Engvangin nge DESFire Credentials hi a man to zawk?
A: DESFire credentials hian chip thiam zawk a hmang a, memory structure him zawk a support a, key management dik tak emaw pre-encoding emaw a ngai fo bawk. A man to zawk hian security capability a pe a, mahse chu capability chu a pawimawh theih nan system chu configure dik a ngai a ni.
Q: Engtikah nge 125kHz hi pawm theih a la nih?
