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.

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.

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.

RFID modules SL102 and SL500A are readily usable and provide many useful functions.

Similarly like in other segments of electronics, even at RFID you have a possibility to assemble a target device from components themselves, from modules, or to use a complete ready-made module, which is pluggable to a PC, often already with a SW included. SL102 and SL500A modules represent the „3-rd group“ from this point of view and provide a ready-to-use RFID solution.

SL102, 125 kHz RFID reader – USB keyboard emulator. That means, that after SL102 appears as a keyboard after connecting to a PC (PC automatically recognizes it). SL102 operates in the way, that after reading an RFID tag, it sends its ID in the same form as if we typed it via a keyboard (and finished it be pushing „Enter“), i.e. every ID is in a new line. It is only necessary to open any program in which it is possible to enter numbers via a keyboard (excel, notepad, word,…). This system is very convenient for example for tracking of goods in production, in stock (stock in, stock out) but also for admission systems and many other.

SL500A,Mifare 13,56 MHz reader/writer with the USB interface (virtual COM device). SL500A is able to read and write Mifare_1k, Mifare_4k, UltraLight and Mifare_ProX cards (ISO14443A, ISO1443B and ISO15693 protocols). SL500A is supplied with the software, including a DLL library and examples. SL500A can be used by a supplied SW, but you can also create your own application best suited to your needs.

Both RFID devices are available directly from our stock. A detailed description will provide you the SL102 and SL500A datasheets.

RFID system DESFire EV1 enables substantially more than only an identification. Access systems, public transportation, loyalty programs, those are only few examples of usage of this system.

Similarly like every system has its hierarchy, even in the RFID can be found simpler but also more sophisticated technologies. DESFire EV1 working at the 13,56 MHz frequency belongs to a top in an RFID, that´s why it can be found mainly in payment systems, public transportation and other areas, where fast read/write on the card, various applications on the card and mainly highly secure communication are beneficial. An advantage of the system is also its anti-collision design – important in the case, when several cards are in the range of a reader. Relatively big memory (2, 4 or 8 kB) enables to store a considerable amount of data in various files. DES/2K3DES and mainly 3K3DES and AES encrypting algorithms takes care for a secure communication.

New DESFire cards in our portfolio DESFIREEV14KISO and DESFIREEV18KISO are suitable for all Mifare/DESFire readers like for example SL040A. For a full usage of cards potential, it is necessary to use a device able to read but also to write, like for example SL032 and SL500A-USB. . Many useful information can be found at www.mifare.net
