This document discusses replacing an existing biometric attendance system brand, Zecons, with a new brand, ESSL, due to Zecons no longer providing support. The key points are: 1) Zecons is no longer supported and replacement devices are unavailable, so a new brand is needed. 2) ESSL provides good technical support and a variety of products on the same platform for future needs. 3) The ESSL system can run alongside the existing Zecons devices and use the current RFID cards while replacing faulty Zecons devices over time with ESSL. 4) This will involve separate ESSL and Zecons software connecting attendance to a shared SQL database and payroll system.

1. Biometric Access
Controller with Attendance
Merging of Two Brand Biometric and
collecting the Attendance Report Without
Disturbing the on going or running
system.

2. Currently Using Zecons
Biometric Device

3. ESSL X990 Biometric which we
are going to change

4. Reason : why we are going to
change the current system
• The brand Zecons has officially stopped giving support.
• We cannot get the same Device if one of our device
goes faulty.
• Even if we go for repair the device, there are no spares
available in market.
• We can better purchase other brand new device, and
replace it.

5. Advantages & Disadvantages of
changing to ESSL
Advantages
• The OEM ESSL provides very good technical support.
• We can get variety of products from the same brand
• In future if we want any new requirement we can use that in same platform.
• We can run the current Zecons devices parallelly with the ESSL devices.
• The product’s software will support SQL server Database.
• We can Use current RFID cards of all employees, no need to change it.
• If Any old “Zecons” Biometric device goes faulty
,we can replace it with ESSL X990 Device immediately, in future.
Disadvantages
• The ESSL device cannot be added into current Zecons software
the Software will be different.

• Now there are two Brands 1. ESSL and 2. Zecons
• The both brands are connected to SQL Server and they will work together and update the
attendance to SQL Server Database, and then SQL server will update the same to Payroll
Software.
• If once the Zecons Device goes faulty we can replace it with ESSL device.

7. If any Zecons biometric goes faulty

• The Biometric number 4 was a Zecons brand earlier, but now the device is faulty,
so it has been replaced by ESSL Biometric and added to ESSL Software.
• The same process will be repeated for the next faulty Zecons Biometrics.
And finally all Biometrics and software will be only one brand, which is ESSL.
