An Arduino-based RFID access control to open garage door using RFID by Jason Hamilton:

This is my Arduino-based project that allows you to use RFID for access control to open a door. The door can be anything that can be controlled by a relay. In my case it will be a garage door opener.
This is the initial prototype. Next I plan to build it on a prototype shield and then if put it on a PCB. The top section of components (Arduino and breadboard) will be placed inside the garage and the bottom section of components (LED, buzzer, NFC/RFID reader) will be placed outside (in a project box).

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

“Replacemen” 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.
Detailed information will provide you the SL040A user manual.

New version of a favorite RFID module ID12LA will enable you to implement RFID into your device even more easily thanks to a wide range of supply voltage.

Literally “globally known” with an integrated antenna – ID12 and its familiar like for example ID2 or ID20 have earned a big popularity thanks to a flawless usage and reliability. Perhaps the only disadvantage of this module was narrow range of operating supply voltage, what in praxis enabled only usage of 5V DC. New version – ID12LA solves also this small drawback and the new module works in a range of 2.8-5VDC. This also enable their usage even with a 3.3V logic and for example in battery operated devices (3-4x NiMH, or 1x Lithium cell, …) without necessity of DC converters or a precise voltage regulation.

The module ID12LA (range approx. 12cm), as well as ID20LA (range approx.16cm) are in our stable stock offer, similarly also the Mifare version (13,56 MHz) – ID20MFIA. In case, that you prefer the maximum range, it´s possible to use module ID2 supplied with an external antenna (range up to 30 cm).

Detailed information will provide you datasheets at particular types below the article.

Admittance control, movement of goods, tickets for various cultural events and sport matches, travel tickets, parking,… thanks to a permanently lower price and bigger possibilities of RFID cards (tags) the Mifare system (13,56 Mhz) in various variations runs forward even to segment where an older 125 kHz system didn´t suite. Complete RFID solution for a very affordable price, it is a short summary of RFID modules features from company Stronglink, which we already introduced to you in several articles.

Group of modules SL03x – SL030, SL031 and SL032 represents complete OEM RFID modules with antenna integrated on a PCB, intended to be built into an end device. All these three modules support Mifare Mini, Mifare 1k, Mifare 4k, Mifare Plus and Mifare Ultralight. SL032 further supports also the DESFire protocol. SL030 has an I2C communication interface, while the SL031 and SL032 have a UART. Modules are controlled by a set of simple commands, thus an integration into a device should cause no troubles even to less-experienced developers.

Closer information will provide you the SL030, SL031 and SL032 user manuals, as well as AN100721, AN101203 and AN110221 application notes.

Thanks to a close cooperation with a producer, we aim to keep a sufficient amount of STRONGLINK RFID modules in stock.

SL030 module communicates through favorite I2C interface and supports a wide scale of secure RFID technologies on the frequency of 13.56 MHz. 

RFID modules Stronglink provide an excellent quality for an unbeatable price, that´s why from now you can find in our store another member of readers/ writers SL0xx module SL030. In many ways is the SL030 similar to other readers of the SL0xx family (especially SL031), which were introduced to you in the article „Stronglink modules will provide you a highly secure RFID”.

SL 030 supports the most of known RFID protocols on the frequency of 13.56 MHz like MIFARE 1k, MIFARE 4k, MIFARE Ultralight as well as NFC NTAG203. Built-in antenna and automatic detection of tags significantly simplify usage of the module. Also positive is the fact, that despite a 3V power supply, the outputs are 5V tolerant, thus combination with a 5V logic should be trouble free. SL030 contain besides an I2C communication interface also a direct output (OUT pin) indicating presence of RFID tag in a reach.   SL030 can be set up to 4 different I2C addresses (1010000-1010011) by means jumpers JP1 and JP2. The communication itself runs in a standard form usual for an I2C bus. Commands (from a  Host microcontroller of your application) are sent in a form of „Start+Address+Data_Length+Command+Data+Stop“. Overview of available commands is displayed in a Table no. 3. Result of operation is sent back from SL030 through I2C in a form of Command+Status+Data. Byte „Status“ indicates result of operation (Success/Fail,…) – table no. 4. Overview of possible statuses is summarized in section 4-3.

Detailed information will provide you the SL030 datasheet and examples of source codes ARM, AVR, MCS51, MSP430 a PIC.
Upon request we´re able to provide you any other Stronglink type within few days. In case of interest please contact us at info@soselectronic.com.

I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 arduino chip and a ID-20 RFID reader to control an electronic door lock.

by Publitek European Editors:

Near-Field Communication (NFC) is an evolution of radio frequency identification (RFID) tag technology that allows objects to respond to the tap of a mobile device. Although the tags are being used for making payments from a wireless bank card or a mobile phone, there are many more applications. NFC takes the identification and low cost capabilities of RFID and extends them with processing and authentication within the NFC tag. This transforms the already dynamic mobile user experience in a way that enables the “Internet of Things”. Tags in “smart posters” or location based check-in signs, games or media content on a friends’ tablet, and ticketing or payment terminal contactless readers can now interact with your mobile device in a secure yet simple way. NFC technology is even being used in secure access systems to replace locks and to provide information on the label of a wine bottle.

by Publitek European Editors:

In today’s wireless, connected world, ambient Radio Frequency (RF) energy is everywhere. Technically, this free-flowing energy can be captured, converted and stored for use in other applications. In fact, it is already in use in a number of ultra-low-power, battery-free applications, such as RFID tags, contactless smart cards, and wireless sensor networks. As a result of technological advances, harvested RF energy is just beginning to realize its wider potential, including charging batteries in smartphones and other portable devices. These enabling technologies include RF transceivers, power conversion circuits, and ultra-low-power microcontrollers, all of which are becoming ever more efficient.

RFID reader / writer SL500F gladly communicates with any 13,56MHz RFID card. 

For a concrete application we usually need only one type of an RFID communication. For the sophisticated devices or for devices intended for configuration of various RFID cards, a reader handling all common protocols can be very convenient.
SL500F, a novelty in our offer, handles ISO ISO14443A, ISO14443B as well as ISO15693, what practically means a support of all common RFID systems working on the frequency of 13,56 MHz. Similarly like SL500A, which we introduced to you in our article – „Plug´n´play“ desktop RFID modules with a USB interface, also for the SL500F there´s a free-to-download software including a DLL library and examples. Detailed description can be found in the SL500 datasheet.

In case of interest, please contact us at info@soselectronic.com.
