zk-protocol

A precise, clean and easy to understand description of the protocol used in ZKTeco devices.

Check the PyZatt lib!!!

Getting Started

This project is part of an effort to build an alternative for ZKTeco's Standalone devices, you should begin by reading the user manual and the Standalone SDK docs, that can be found in ZKTeco's SDKs Download page.

Then begin with the main page:

• protocol.md

Protocol related operations are grouped in the following sections:

• ex_data.md: Protocol for the exchange of large amounts of data.
• terminal.md: Protocol for procedures to get/set device parameters.
• data-user.md: Protocol to manage the users data.
• data-record.md: Protocol to manage records.
• access.md: Protocol to manage the access settings.
• realtime.md: Protocol of the realtime events.
• other.md: Other procedures.

Develop

Currently this spec is intended for devices of the TFT series, but there's no reason to keep it that way.

Make contributions to the develop branch under a pull request.

Capture files of network traffic of documented tests are welcomed.

zk-protocol's Issues

zkteco firmware

How can I get the firmware？


I tried to get data from flash (maybe,not sure), however, It is can not identifed by the software

Polling a device to get attendances log

Hi mate, sorry to open a issue to ask you something but it may be useful to someone else.
I've chance to buy some ZkTeko fingerprint devices for a reasonable price, but it doesn't support ADMS. As now ADMS is the only way I know to get attendances from Filemaker, I mean it allow terminal send immediatly the attendance to the ADMS server, that will fill up its database; it is just necessary then to poll often the server database, to get the infos. A bit complex but it works.

It can be much easier if with the protocol you discover we can poll directly the terminal, just for ask attendances, I suppose the terminal replies with all attendance in its memory, we can do so about each minute. Maybe there is a plugin for Filemaker to manage/send tcp ip packets. Do you think it's possible? This protocol simulates Access (software) so I guess it will work with any device.
Thank you for kind answer

Is it possible to convert finger print template to image?
