Data I O Chip Writer Software. Data I/O is choosen by 8 out of the top 9 automotive manufacturers to program mission critical automotive applications.

I am working on an RFID-based inventory control project, and I want to make a writer through which I can write data on each passive RFID tag. How can I accomplish that?

• Introduction This document describes the functionality and electrical specifications of the contactless reader/writer MFRC522. Remark: The MFRC522 supports all.
• Many of these work with TaskLink, while others are independent software packages. Data I/O manufactures two device programmers that can accommodate DIP (through-hole) devices, the Plus-48 and the Optima. Both are aimed at the small, (relatively) low-cost, desktop programmer (engineering) market.

Depending on your budget, it may be much simpler to purchase an RFID reader (which is also a writer) than to make one. There are many great readers on the market with fairly easy to use APIs. Also, most of the major UHF RFID readers work with a common standard called LLRP (Low Level Reader Protocol); so, you can write one set of code and it will work with any reader that supports LLRP. The vast majority of UHF RFID tags work on the gen2 protocol (ISO 18000-6C), so just be sure your reader/writer does as well.

Assuming you are using a gen2 RFID tag, writing to the tag is fairly simple. You simply tell the reader (via a command) to encode the tag. Of course, there are a few considerations to note such as encoding must be in hexadecimal format and there are a few different memory blocks on the tag - EPC, Reserved, TID, and User. (Note: you can't encode to all memory blocks. For more basic information on this topic, see this blog post: http://blog.atlasrfidstore.com/types-of-memory-in-gen-2-uhf-rfid-tags.)

Another thing to consider is how much data you would like to encode to the tag. The two primary memory blocks you'll be using are the EPC (typically 96 bits, but, on some tags, this number can be higher) and User (about 512 bits is standard, but there are some gen2 tags on the market that have much higher User memory).

RFID reading and writing is still specific to the technology of the tags, the hardware reader, and to the software device drivers. There is no common Windows API for RFID. However, there is a standard called UnifiedPOS that provides a wrapper around RFID scanners that makes them all behave the same. You write your app once to the UnifiedPOS interface, then you can use any RFID scanners that have a UnifiedPOS compatible Service Object. It's available as OPOS for Windows, and 'JavaPOS' for Java. There is also Microsoft's POS for .Net.

When selecting the hardware for the tags and readers, consider if the manufacturer provides compatible service objects. It will make reading and writing much simpler.

Get an RFID reader: http://www.atlasrfidstore.com/RFID_reader_s/29.htmOr build one: http://www.impinj.com/Indy_Reader_Chip_Family.aspx

I would recommend using one of these bad boys.Scanfob® Ultra-BB2 GEN2 (UHF) Bluetooth RFID Reader/Writer https://serialio.com/products/rfid/readerwriters/scanfob%C2%AE-ultra-bb2-gen2-uhf-bluetooth-rfid-readerwriter

This will allow you write user data to a tag using Android or Windows with SerialMagic (license for SerialMagic embedded in Scanfob®Ultra-BB2).

This reader is also compatible with Mac OSX & iOS. Only capable of reading tags to cursor location (Bluetooth HID) on iOS.

RFID is a magnetic tag, so If you've some good knowledge in this subject, you can build it but I think (I don't know exactly the process) that it's pretty hard to do..

However, I know there is an Arduino NFC Shield which can, maybe help you. Something like this: http://www.adafruit.com/products/789

I'm not sure if by 'writer' you mean hardware (+ software) or if a software satisfy your needs. @Gp2mv3 mentions NFC, so if your tags fall into the NFC type subset of RFID, the simplest is to grab your phone, download a free NFC writer app and use that.

If you want to write your own software, for Android platform there are a lot of examples, and I assume it's the same for other platforms too. I can imagine even a setup where you connect your phone to your PC through USB and you use it with a hybrid PC + mobile app companion software as a writer.

FeliCa is a contactless RFIDsmart card system from Sony in Japan, primarily used in electronic money cards. The name stands for Felicity Card. First utilized in the Octopus card system in Hong Kong,^[1] the technology is used in a variety of cards also in countries such as Singapore, Japan, Indonesia and the United States.

Technology[edit]

FeliCa's encryption key is dynamically generated each time mutual authentication is performed, preventing fraud such as impersonation.

FeliCa is externally powered, i.e. it does not need a battery to operate. The card uses power supplied from the special FeliCa card reader when the card comes in range. When the data transfer is complete, the reader will stop the supply of power.

FeliCa was proposed for ISO/IEC 14443 Type C but was rejected^{[citation needed]}. However, ISO/IEC 18092 (Near Field Communication) uses some similar modulation methods. It uses Manchester coding at 212 kbit/s in the 13.56 MHz range. A proximity of 10 centimeters or less is required for communication.

FeliCa complies with JIS: X6319-4: Specification of implementation for integrated circuit(s) cards - Part 4: High speed proximity cards. The standard is regulated by JICSAP (Japan IC Card System Application Council).

The UK IT security evaluation and certification scheme provides more detail as to the internal architecture of the FeliCa card (RC-S860 ). FeliCa IC card (hardware) and its operating system has obtained ISO15408 Evaluation Assurance Level 4 (“EAL4”), a standard which indicates the security level of information technology and consumer products.

FeliCa is also included as a condition of the NFC Forum Specification Compliance.^[2]

The next generation of FeliCa IC chip announced in June 2011 will have enhanced security adopting the Advanced Encryption Standard (AES) encryption.^[3] Sony claims the next generation chip will have a higher performance, reliability and lower power consumption.^[4]

Reliability[edit]

FeliCa supports simultaneous access of up to 8 blocks (1 block is 16 octets). If an IC card is moved outside of the power-supplied area during the session, the FeliCa card automatically discards incomplete data to restore the previous state.

Mobile FeliCa[edit]

Mobile FeliCa is a modification of FeliCa for use in mobile phones by FeliCa Networks[1], a subsidiary company of both NTT DoCoMo and Sony. DoCoMo has developed a wallet phone concept based on Mobile FeliCa and has developed a wide network of partnerships and business models. au and SoftBank (former Vodafone Japan) have also licensed mobile FeliCa from FeliCa Networks.

The Osaifu-Keitai (おサイフケータイ) system (literal translation: 'wallet-phone') was developed by NTT DoCoMo, and introduced in July 2004 and later licensed to Vodafone and au, which introduced the product in their own mobile phone ranges under the same name. Using Osaifu-Keitai, multiple FeliCa systems (such as Suica and Edy) can be accessed from a single mobile phone. On January 28, 2006, au introduced Mobile Suica which is used primarily on the railway networks owned by JR East.

On September 7, 2016, Apple announced Apple Pay now features FeliCa technology. Users who purchased iPhone 7 or Apple Watch Series 2 in Japan can now add Suica cards into their Apple Pay wallets and tap their devices just like regular Suica cards.^[5][6] Users can either transfer the balance from a physical Suica card to the Apple Pay wallet, or create a virtual Suica card in the wallet from the JR East application.^[7] On September 12, 2017, Apple announced new iPhone 8, iPhone X and Apple Watch Series 3 models featuring 'Global FeliCa', i.e. NFC-F and licensed FeliCa middleware incorporated in all devices sold worldwide, not just ones sold in Japan.^[8]

On October 9, 2018, Google quietly announced that its latest Pixel device, the Pixel 3, would support FeliCa in models purchased in Japan. This feature enables support for WAON, SuiCa, and various other FeliCa-based services through Google Pay.

Consumer reader/writer devices[edit]

Sony has built a FeliCa reader/writer known as 'FeliCa Port' into their VAIO PC line. Using the device, FeliCa cards can be used over the Internet for shopping and charging FeliCa cards.

An external USB FeliCa PC reader/writer has been released as well, called PaSoRi. It is USB powered and allows one to perform online transactions and top up EZ-link cards in Singapore with credit cards or debit cards anywhere, as long as there is direct access to the Internet.

The Sony PaSoRi Reader is not compatible with the new ez-link cards.^[9]

Integrated services in Japan[edit]

As FeliCa is the de facto smart card ticketing system standard in Japan, many of these cards have integrated services. A particular region/operator may accept multiple cards.

The table below shows the integrated services FeliCa cards have for each Japanese region.

A: The area accepts all functions of the card, including electronic money function. (There may be subtle differences between each area.)

B: The area accepts basic functions of the card, but not some functions such as electronic money or auto recharging.

A: The area will introduce the new card in the future.

F: The area will accept the card in future.

A few cards can be used as electronic money in some unmarked areas.

¹: In many cases, there are multiple operators accepting the same card in the same area. See each card article for the full listing.
