What is the composition of the memory of a UHF EPC Class1 Gen2 tag?
A:
The memory of an RFID chip varies from one chip to another. It is divided into several types of memory: EPC (Electronic Product Code), TID (Tag Identification Code), User (User Defined Area), Reserved (Reserved Area).
What are the different types of memory: TID, EPC, USER and Reserved?
Q:
What are the different types of memory: TID, EPC, USER and Reserved? Can information be stored in all these types of memory?
A:
- TID: The manufacturer’s unique identification number is written into the TID memory. This number cannot be changed and is unique.
- EPC: The UHF tag identification code, which can be unique written to the EPC memory. This number can be assigned to the UHF EPC Class1 Gen2 tag by coding.
- User: User memory is optional. The RAIN RFID tag allows reading and writing in the chip memory. It is itself divided into several blocks. Access to these different blocks can be locked to specific users.
- Reserved: Store Kill Password and Access Password, which allows you to lock the read and write functions of RFID chip data, especially in the case of sensitive or confidential data.
How much data can the EPC write?
A:
The EPC can follow the GS1 standard which guarantees the uniqueness and authenticity of the codes. Commonly, the EPC memory is 96-bit and 128-bit. The general read device by hexadecimal display 24 HEX and 32 HEX, respectively. The current conventional chip can support up to 496-bit (124 HEX).
Can EPC data be shorter?
A:
The length of the EPC can be controlled by modifying the PC of the EPC, which can be written as a minimum of 8 HEX, i.e. 32-bit. Considering the system compatibility, it is generally not recommended for customers to modify the PC . The 96bit complementary 0 scheme has better stability and compatibility.
Can EPC write text data directly? How does it work exactly?
A:
Usually, the rain RFID tag is only used as a identification, and it is not recommended for customers to write text data directly. If some special needs must write text, you can use ASCII code to write, every 2 HEX can write a character, so 96-bit EPC can write 12 characters, 128-bit EPC can write 16 characters.
What is the purpose of TID?
A:
The TID is used as a chip identifier and can be used as a UHF tag verification to prevent EPC impersonation or traceability.
TID consists of fixed chip code + serial number, fixed chip code can be used as a confirmation of the chip model, generally we can confirm the chip model through the first 8 bits of the TID HEX.

What are the encryption means for EPC data?
A:
The EPC can be restricted from being rewritten by setting a password for the EPC, and only with the correct password can the EPC data be rewritten. In addition, you can also verify the legitimacy of the tag by binding the EPC and TID in the system.
Card Inlay layout for card production
As we know, the card inlay (card prelam) is normally used for the card production, and the size should be exactly the same as customer’s device, or else it will be unuseful.
We’d like to get card inlay (card prelam) layout or draft to evaluate if we can provide it first. So that we could quote a favorable price soon.
What’s The Difference Between NFC Card & Mifare 1k Classic Card ?
Q:
We are small software company based in Sydney Australia. We focus to Point of sale system for hospitality and retail. We would like to use your NFC cards in our customers shops for customer loyalty program. What’s The Difference Between NFC Card & Mifare 1k Classic Card ?
A:
1, The products you need is our professional main products in 10 years;
2, NFC card with MIFARE 1K chip is common products can read by most of NFC mobile, but in some Samsung mobile or HTC mobile may cannot read it, of mifare class IC is not full compatible for NFC protocol. you’d better used NTAG Chip or compatible which can be accepted for every NFC facilitys
3, I suggest not only card size, it might be a little boring for some younger, there are many stylish design like stickers keytag, epoxy tag, silicon tag, etc, please found attached catalogue for your reference;
4, We had some big client is Australia, we had offer years for the biggest cafe company with NFC loyalty cards.
5, Please feel free contact me if any thing I can help .
Does HUAYUAN have lots of experience in card ticketing projects?
Q:
Our customer is a company delivering road toll and ticketing solutions here · They are establishing a RFID or NFC ticketing card .
I have some initial questions:
1) We need to convince the customer that HUAYUAN as our supplier has lots of experience in ticketing. Could you provide me information about Huayuan’s RFID card ticketing experiences? Primarily information about scale of business and cases would be highly appreciated. Both information about sales globally and Northern Europe/Scandinavia-specific information would be useful.
2) The customer will be concerned about quality assurance. Could your provide information about your quality assurance measures for making sure that the cards are personalized correctly and will work correctly?
3) Which is the most commonly used chip for ticketing cards for LF RFID, HF RFID and NFC respectively?
A:
HUAYUAN, my company is a professional card manufacturer for 21 years, we are the member of ICMA.
We have rich experience in card production for public transportation, most of them assembling MIFARE classic 1k, or Ultralight or Ultralight C, for alternative purpose in e-ticking, any and our main market in Europe.
It’s very serious and security for prepaid card or cashless payment, the system integrator had been meticulously designed base on whole system software, data server, system sever, data configuration of card, and terminal reader and facility corresponding in AFC system. So we had right to define chip of card, even the content of data inside card, they will share encryption detail information only after a formal.
NDA contract between us if they need card initialized at our side.
And your country will not accept PVC card for there is a regulation for many years in environmental protection, only PETG card with very good offer above.
Please try your best to get detail specific requirement of cards for this project, then we had chance to going on.
How to prepare the card printing design ?
Printing design is JPG or only convert it to .cdr that is not able to print in printing industrial .
Photoshop .JPG is not able to print. Please send card design in .cdr(corelDRAW) or .AI(Illustrator) format. There are several characters of the .cdr or .ai format.
Firstly it is made up of several parts and any part is separate(picture part and letter part is separate.If the letter is in two kind of language,they are also separate. ) that could be modified;
Secondly there is C,M,Y,K data in vector file.
Thirdly.when you magnify the card desigh in .cdr or .ai format(or you convert it to .psd),it is still clear enough.If the card design is .psd or eps format,it is a whole(not made up of seperate parts and couldn’t be modified.Besides when you magnify it(in .psd or .eps,etc or you convert it to .cdr),it is blurry.
Sample picture(vector file) for your reference,please open it and you will find the characters.
Artwork Specifications:
CLEAN, BLACK AND WHITE LINE ART is required;
CDR, PDF or AI files are required;
Tones and screens need to be converted to solids;
Broken lines, weak lines, or smeared art cannot be imprinted;
Outline all fonts in the artwork files;
File resolution must be over than 300DPI;
PS:
We cannot use logos/artwork that are copied from a website as these images;
