Zero exposed screws, 350,000 continuous reads, 7,200 records — the tamper-proof workhorse.
The TS-G400 is a very popular reader where small size, durability and low power consumption matter most. With a unique design and special internal adhesive it is totally waterproof, and because there is not a single screw on the surface it is exceptionally tamper resistant. One 3V lithium battery supports up to 350,000 continuous reads. If you need a dependable, tamper-proof data collection system, the TS-G400 is the obvious choice.

A guard tour system is a patrol verification tool that records proof a security guard was at a specific checkpoint at a specific time. This guide explains how it works, the technology behind it, and how it differs from a paper logbook.
Installing a guard tour system means placing checkpoints, issuing readers, and setting routes in software. This step-by-step guide covers a typical site rollout, including the passive tags that need no power or wiring.
At its core a guard tour system turns the question of whether a guard actually patrolled into a verifiable record. This article follows the data from a single checkpoint read to the final report.
A guard tour reader is not a consumer gadget — it is carried by guards who, knowing they are being monitored, may try to damage it to skip patrols. This article explains why tamper resistance matters and how the hardware is built to survive.
