In order to provide integral services while implementing our solutions, we offer equipment and accessories that complement the functionality of Sistema Tress.

Some examples of accessories we offer: 

Alarms and Speakers		Useful in conjunction with Cafeteria and Attendance modules.  The audible signal allows the employee to know if their card was read correctly or if the system allows them to proceed on the queue for food.  They are also used to announce start times, breaks, and the end of shifts.
Light signals		Useful in conjunction with Cafeteria and Attendance modules. Visually displays correct or incorrect employee check-in/out, by turning on green or red lights.
Batteries		Prevent damage to the terminal’s motherboard due to electronic failures.
Power source		Continually feeds the battery.
Regulator		Maintains a continuous feeding voltage for data terminals, avoiding damages caused by voltage variations.  It is recommended to install it along with the battery.
Door synchronization		Enables integration with Access Control systems.
Pasage barriers		To ensure employee check in.  The barrier allows entrance only after a valid check-in at the data terminal.
PVC badges Printer			Evolis Dualys 3 equipment, for printing color PVC ID badges, either on one or both sides.
Ink cartridges			For Evolis Dualys, Eltron, and Fargo name badge printers.
ID badges			PVC and Teslin type badges with strips that can be black, red, double black horizontal, black vertical, used to prevent copying of the badge’s bar code; or without strips.
Data terminals			GTI always looking for the best options for its clients, has found in three suppliers: Linx, Unitech, and Bioscrypt the terminals that provide a solution for handling electronic check-ins and check-outs.  We offer a Linx model for barcode information registration.  Two Unitech models for information registration either by barcode or proximity.  And, looking at new alternatives for attendance control, offering higher levels of security to better comply with the paradigm of security and organizational control, we offer three Bioscrypt terminal models, making use of biometrics technology.
Kiosk module peripherals			With the Kiosk module, the employee is able to access information that the Human Resources department makes available.  To this end, equipment that makes this access easy and atractive is needed.  GTI offers options that, according to an in-depth evaluation, have the best results in functionality, cost, and durability.
