Express Order System, Inc.

EXpress Order System, Inc. (EXOS) is a sister company of Truth Verifier Systems, Inc. (TVSI), a private detective company noted for its exemplary service, expertise, integrity and truthful reporting.

Being in the investigation and security consultancy field since 1966, TVSI President Conrado G. Dumlao saw the need of the Security Industry, Law-enforcement agencies and Criminology schools for quality products, particularly, US-made products that fit and meet the demands of the cyber age. Thus, Truth Verifier Systems, Inc. became a distributor of US-made security and crime laboratory equipment and supplies. It joined in government biddings and had supplied NBI and PAGCOR with brand new Lie Detector/Polygraph Machines. TVSI is the only lie detector company which uses a Lafayette Computerized Polygraph. TVSI also won the biddings and delivered Fingerprint Kits to the Philippine National Police and crime laboratory equipment and supplies to Philippine Public Safety College.

Consequently, EXpress Order System, Inc. was formally put up on January 1997 to cater to the law-enforcement, crime laboratory and security products needed by government agencies, criminology schools and private firms and individuals. With this, TVSI could focus on its main business which is detective, investigative and lie detector services.

At present EXpress Order System, Inc. (EXOS) wholesales and retails quality products which include Law Enforcement/Security products, Crime Laboratory Equipment & Supplies, CCTV and others. It carries the Lafayette Polygraph Instruments USA, Garrett Metal Detectors USA, Security Plus Defense Sprays USA, Polygraph Charts USA, Fingerprint Equipment & Supplies, Hiltra Technologies & Counterfeit Detection, Photo Enlargers & Microscopes for Training and Research.
