Appendix 5 AntiPass Back ★

【overview】

Sometimes, some illegal people follow the other one into the gate, which will cause the security problems. To prevent such risks, this function is enabled. The In record must match the Out record, or the gate won’t open.

This function needs two machines to work together. One is installed inside of the door (master machine hereinafter), the other is installed outside of the door (slave machine hereinafter). Wiegand signal communication is adopted between the two machines.
【Working principle】

The master machine has Wiegand In and slave machine has Wiegand Out functions. Connect Wigand Out of slave machine to Wiegand In of master machine. Wiegand output from slave machine must not own machine ID. The number sent to master machine from slave machine must be found in the master machine.

【Function】

Judge whether it is antipass back according to user’s recent inout record. In record and out record must be matched. This machine supports out, in, or outin antipass back.

When the master machine is set as “out antipass back”, if user wants to come in and go out normally, his recent record must be “in”, or he cannot go out. Any “out” attempt will be refused by “antipass back” function. For example, a user’s recent record is “in”, his second record can be “out” or “in”. His third record is based on his second record. Out record and in record must match.（Notice: If customer has no record before, then he can come in but cannot go out. )

When the master machine is set as “in antipass back”, if the user wants to come in and go out normally, his recent record must be “out”, or he cannot go out. Any out record will be “antipass back refused” by the system. (Notice: If the customer has no former record, then he can go out, but cannot come in).

When the master machine is set as “outin antipass back”, if the user wants to come in and go out normally, if his recent record is “out” and “in”, then his next record must be “in” and “out”.

【operation】

1. Select model
Master machine: The machine with Wiegand in function, except for F10 reader.
Master machine: The machine with Wiegand in function, except for F10 reader.

2. Menu setting
Antipass back
There are four options: in/out antipass back, out antipass back, in antipass back, and none.
Out antipass back: Only user’s last record is inrecord, can the door be open.
In antipass back: Only user’s last record is outrecord, can the door be open.
Device status: There are three options: Controlin, controlout and none
Controlin: When it is set, the verified records on the device are inrecords.
Controlout: When it is set, the verified records on the device are outrecords.
None: When it is set, close the device’s antipass back function.

3. Modify device’s Wiegand output format
When the two devices are communicating, only the Wiegand signals without device ID are received. Enter device menu－> communication option－> Wiegand option or enter software > basic setting > device management > Wiegand, to modify “defined format” as “wiegand26 without device ID”.

4. Enroll user
The user must be on master machine and slave machine at the same time, and user PIN must be the same. Therefore, it is necessary to enroll user on master machine and slave machine at the same time.

5. Connection instruction
Wiegand communication is adopted for master machine and slave machine. Refer to the following for connection:

Besides this function only is owned by the fingerprint access control machine that has  been  appointed, most  of the fingerprint machines only  have two ways to verify by fingerprint and password, we provide a personal or group Multi­combination Authentication Mode for high security Access control area, verification  type  main  include  five  elements  that  are  User  Number  (PIN), Fingerprint (FP), Face (FACE), Password (PW) and RF card (RF), which can combine into multi­combination.

Note: The RF card is used for ID card verification, the function of ID card  verification  only  is  validity  in  the  machine  which  ID  card  function  is provided with.

These symbols illustrate what follow the table different means.

If Fingerprint, Face, Password and Card have been enrolled for the user, the verification procedure is follow.

 Note: For combined verification, it is better to enroll all the elements in need for using verification mode, or verification will fail.
For example: User “A” use fingerprint for enrollment, while password is used for verification, then the user cannot pass the verification.

Appendix 3 Photo ID Function
The Photo ID function is used to display the photo enrolled by a user or stored in a USB disk on the screen in addition to such information as the user ID and name.

[Operation Steps]
1. When the photo taken by the device is used, the photo can be displayed upon successful verification.
2. To use a photo stored in a USB disk, proceed as follows:
1) Create a folder with the name of “photo” in the USB disk, and store users’ photos under this folder.
2) The user photos must be in JPG format and named after their IDs. For example, for the user with the user ID of 154, the photo name must be 154.jpg.
3) Insert the USB disk into USB slot on the device, and select USB Disk Management > Upload > Upload Photos. Then user photos can be displayed upon successful verification.

Note:
1) The length of a user name cannot exceed 24 digits.
2) The recommended size of a user photo is less than 30 kbit.
3) The uploaded new user photo will overwrite the existing photo in related to the user ID.
4) To download user photos, select USB Disk Management > Download > Download User Photos. A folder with the name of “photo” will be automatically created on the USB disk, and all downloaded user photos are stored under this folder.

Wiegand26 is an access control standard protocol established by the Access Control Standard Subcommittee affiliated to the Security Industry Association (SIA). It is a non­contact IC card reader interface and output protocol. Wiegand26 defines the interface between the card reader and controller used in the access control, security and other related industrial fields. Wiegand26 helps  standardize  the  work  of  the  card  reader  designers  and  controller manufacturers. The access control products manufactured by our company are also designed by following this protocol.

Digital Signals

The  figure below  is  a  sequence  diagram in  which  the  card  reader  sends digital signals in bit format to the access controller. In this sequence diagram, Wiegand follows the  SIA’s  access control standard  protocol for the  26­bit Wiegand card reader (one pulse time ranges between 20 us and 100 us, and the pulse jump time ranges between 200us and 20ms). Data1 and Data0 are high level (larger than Vol) signals till the card reader prepares to send a data stream. The asynchronous low­level pulse (smaller than Vol) generated by the card reader is sent to the access control panel (The saw­tooth wave as shown in Figure below) through Data1 or Data0. Data1 and Data0 pulses will neither overlap nor be generated synchronously. The table below lists the maximum and minimum pulse width (a consecutive pulse) and pulse jump time (time between pulses) allowed by the F series fingerprint access control device.
