With the ID3LA RFID module it’s possible to read a tag up to 30cm

obr1719_uvod

A possibility to read an RFID card even on a longer distance is usually highly appreciated at its everyday usage.

As we know, RFID module range is expressively depending on a size and shape of the RFID antenna (coil). That´s why the module with a big antenna has a potentially bigger chance to reach a long range. This is exactly a case of the ID3LA module – working in a wider operating voltages range (2,8-5V) than its predecessor – the ID2 module. This enables its usage even with a 3.3V logic and also for example in battery-operated devices (3-4x NiMH, or 1x Lithium cell, …) not requiring DC converters or a precise voltage regulation.

ID3LA belongs to the „ID3/ID12/ID20“ family with very similar electrical parameters and a way of usage. All modules of this family function as readers sending data – a unique ID of a given RFID tag. The most favourite type – ID12(LA) has a very decent range (approx.. 12cm) sufficient for majority of applications. However, if the space in your application allows you to use ID3LA, you´ll reach a significantly longer range. ID3LA requires an external antenna – included in the package, as illustrated on the attached pictures.

Detailed information will provide you the ID3LA datasheet.

Printable Chipless RFID Tags

ChiplessBarcodes

A new generation of chipless RFID tags could soon be set to replace standard product barcodes. A research team at Monash University led by Dr Nemai Karmakar, from the Department of Electrical and Computer Systems Engineering, have been developing chipless radio frequency identification (RFID) tags that can be printed directly onto products and packaging – including postal items, drugs and books – potentially making this new technology cheaper, smaller and faster than any other tracking system on the market.

The team have succeeded in producing fully printable tags for products made of metal and containing liquids including water bottles and soft-drinks cans. Until now, this hasn’t been possible because metal and liquids interfere with the technology. The tag can be printed using an inkjet printer and read when they are attached to reflective surfaces such as metal cans and water bottles.

Simple RFID based Door Lock using Arduino

Simple_RFID_based_Access_Control

by JOJO @ circuitstoday.com:

Its quiet fun to work with RFID based projects! In the previous article, we saw how to interface RFID with Arduino. Interfacing is the first step to create any useful project. So why don’t we create an RFID based Access Control System or an RFID based Door Lock using Arduino? The system I have designed here is a simple version of the project. This project can be enhanced with a lot of features (which I will be doing in the next version of this project – Advanced RFID based Door Lock). So lets begin!

Custom DIY RFID smart lock

In this video Craig demonstrates his custom DIY RFID smart lock project:

The goal of this project was to design an inexpensive rfid door lock which could be opened via smart phone, and have all activity logged w/o utilizing any 3rd party servers or cloud hosting.

GE RFID tech turns stickers into explosives detectors

By David Szondy @ gizmag.com:

A global economy brings many benefits, but it also makes international terrorism extremely difficult to combat. With more goods passing through the world’s shipping terminals and airports than ever before, hunting explosives with large, static detectors or teams of inspectors armed with detecting devices and reagents is a bottleneck that increases the chances of evasion. To help US counterterrorism efforts, GE has developed RFID stickers that act as wireless, battery-free explosives detectors that can be placed almost anywhere.

Ultralow-power RFID transponder chip in thin-film transistor technology on plastic

by Hanne Degans @ phys.org:

At this week’s IEDM 2014, held in San Francisco, California, nanoelectronics research center imec demonstrated an ultra-low power RFID transponder chip. Operating at sub 1V voltage and realized in thin-film transistor technology (TFTs) on plastic film, the chip paves the way for universal sensing applications, such as item level RFID tagging, body area networks (BAN) and environmental monitoring, that require prolonged remote autonomy, and ultimate thinness, flexibility and robustness.

One of the major drivers of the semiconductor industry is the Internet of Things (IoT). Market studies envision a society where billions of autonomous sensor nodes are seamlessly integrated into objects, in the environment and on human bodies, operating independently for months, interacting with each other and connecting to the internet. This IoT is expected to improve and enhance daily-lives through smart houses and smart cars, personal health monitoring and much more.

Wireless sensor alerts your smartphone as food begins to spoil

While the stench of rotting food would cause you to stop from chowing down, chances are it became unfit for consumption some time before those funky aromas wafted through your nostrils. Chemists at MIT have been working on a wireless, inexpensive sensor that, among other things, identifies spoiled food early by detecting gases in the air. It then shares its data with a smartphone, potentially alerting users to that soon-to-be moldy fruit in the bottom of the fridge.

SL040A will load it to you directly into a table sheet

RFID keyboard emulators are able to significantly simplify tracking of goods.

“Replacement” of a keyboard in a form of an RFID module connected to a USB port works very simply – UID of every tag, which will appear in its range will send to a computer – the same way as if we typed it in by a keyboard. SL040A also enables to choose, whether we want the reader to send only data, or also a „CR“ character after every UID (as if an Enter key was hit). It means, that if we already have a software to type in open (for example Excel), the reader itself will fill the cell with data and move the cursor to another cell. SL040A is even able to read data (not only UID) from Mifare tags.

SL040A is also interesting by one feature – on a request from our company SOS electronic, the producer started to produce also the black version SL040A black. Thanks to the above-standard close relationship with the producers, we´re able to supply you even various special customized versions.
Detailed information will provide you the SL040A user manual.
