RFID technology is based on clear scientific principals. Tags gather the projected energy of radio waves in an electromagnetic field. The tags then reflect back an altered signal using a technique called back-scatter which the antennas receive. Because it is a science, it is often assumed that an expert can accurately predict both the read [...]

A few months ago, we published a history of where Wiegand came from and a "light-on-technical-details" overview of how it works.  For those of us that are more engineer-y, it left a bit to be desired.  For me in particular, I recently was doing some low level work with one of my engineers.  We were [...]

Recently, our CEO, David Carta, called me into his office and asked me, “Mark, what is Wiegand?” He was instructing a new Telaeris employee about XPressFreedom, our Wiegand to Ethernet converter which we use to enable mobile access control with existing system. He thought that I, as our sales lead, should be able to give an appropriate [...]

Barcoding on Android Most of the time when employees at Telaeris publish here, it is for real life examples related to our products.  This allows us to discuss a wide area of topics, including barcodes and RFID usage, security or safety system implementation or tips on running a business.  But at the heart of what […]

The group here had a little fun this Christmas and wanted to share it with our friends. We hope you are able to enjoy time with your family during this holiday season. The video is especially relevant as we recently deployed our XPressEntry solution using 900 MHz UHF cards to manage access for ski resort […]

The SmartAT870 is a lightweight and rugged (IP65 rated) mobile unit manufactured by SmarTerminal that Telaeris resells. It is an outstanding device, capable of reading most RFID tags, barcodes, and smart cards available. We get lots of questions regarding what this device can do, so this article discusses most of the capabilities of the SmartA T870 for […]

It recently occurred to me that this year marks my 20th year of experience with RFID. In 1992, my dad, David Carta Sr., had a customer in Chile who wanted to be able to identify cattle electronically using something called “RFID”. The end user wanted a working sample program and hardware to show how RFID […]

This article is a little more technical than most of what we put out, but we thought it would be useful to share with others. When customers order EPC-GEN2 Type UHF RFID tags from us, they often want a product that also has both a human readable number as well as a barcode. And in […]

What is the Cost of Safety? People don’t like to talk about it, but there are costs to safety. The standard reply to satisfy legal is: “We comply with all regulations to keep our people safe” There are always tradeoffs when it comes to safety. If you look at most evacuation drills that take place, […]

When customers order tags, most of the time they don’t care what type of barcode they use – it just has to work. In most cases, your barcode scanner will likely support any 1D barcode. So why should you choose one barcode symbology over another? We choose to use Code 39 (sometimes called Code 3 […]
