Product Description
What the Dahua ASR1102A(V2) does
The ASR1102A(V2) is a fingerprint and RFID reader for access control, verifying identity by contactless card or fingerprint before passing that decision on over the wire. It is a reader, not a standalone controller — it needs an RS-485 connection to a compatible access control panel that actually drives the lock, so spec it alongside one.
Card technology — check before ordering
The standard ASR1102A(V2) reads Mifare 13.56MHz IC cards. The ASR1102A-D(V2) variant reads ID EM cards instead — same hardware, different card tech, so match the version to the credentials you plan to issue.
Key specs
- Fingerprint capacity: up to 3,000 templates stored on-device
- Card type: Mifare IC (standard) or ID EM (“-D” variant)
- Communication: RS-485 protocol
- Feedback: blue backlight, audible beep, LED indicator
- Reliability: watchdog function guards against device halting
- Mounting: surface-mounted
Where it fits
On-device fingerprint storage means the reader keeps verifying even if it loses contact with a back-end server, which suits offices, retail premises, warehouses and residential blocks wanting a single door reader that doesn't depend on constant network access. Surface mounting keeps installation straightforward on most door frames and walls where a flush-mount recess isn't practical.
Confirm your access controller supports RS-485 fingerprint/card readers before adding this to an order, and choose the "-D" variant only if your card stock is ID EM rather than Mifare.

Frequently Asked Questions
Does the ASR1102A(V2) unlock the door by itself?
No — it's a reader that verifies fingerprint or card and passes the decision via RS-485 to a separate access controller, which drives the lock.
How do the ASR1102A(V2) and ASR1102A-D(V2) differ from one another?
The standard version reads Mifare 13.56MHz IC cards; the "-D" variant reads ID EM cards instead, on the same hardware.
How many fingerprints can it store?
Holds up to 3,000 fingerprint templates within the unit itself.
How does it connect to the rest of the system?
Via RS-485 protocol to a compatible access control panel; it also has a watchdog function to help prevent the device from halting.
