RFID (Radio Frequency Identification) card is a contactless smart card with RFID chip and antenna embedded inside.
You can never tell what you hold is a normal PVC card or an RFID card just from the appearance.
When the reader reads or writes the RFID card, reader will send 2 parts of signals; one part is sent to the card, RFID card receive the signal and syntonize with the L/C to generate an instantaneous energy for supplying the RFID chip; the other part will order the RFID chip to change and store the data, and return to the reader, in order to complete the reading / writing operation.
Protocol: ISO 11784 / 11785
Short reading range, around 1-5 cm
Available for read only or readable and writable;
Stable signal with low data speed;
Can read one tag only at one time.
Usually used for access control and animal identification
Protocol: ISO 14443A / 14443B / 15693
Short reading range, around 2-10 cm
(ISO 15693 RFID cards & tags could reach up to around 1 meter)
Readable and writable;
Available for encryption, some support AES-128;
Signal could be influenced by metal, regular data speed;
ISO 15693 is anti-collision (multiple tags could be detected at one time).
P.S.: NFC is a special category from HF, frequency is the same, 13.56 MHz but protocol is ISO 18092. Not like RFID has different blocks and sectors for encoding, the main feature of NFC is it’s NDEF format. You can tell from its name that the reading range of NFC is very short (NFC is short for Near Field Communication).
Suitable for high-security projects like financial, anti-counterfeiting, ID card, license, bank card, credit card, etc.
Protocol: ISO 18000-6B / 18000-6C (UHF Class 1 Gen2)
There are 2 standards for UHF;
Europe: 865-868 MHz
North America: 902-928 MHz
Different countries will apply different standard as per the country’s
related policy (for readers only, tags and cards are not limited)
Long reading range that could reach up to 15 meters;
Readable and writable;
Available for encryption, some supports AES-128;
Signal could be easily influenced by metal, water, wall, human body, etc.;
High data speed;
Anti-collision (multiple tags could be detected at one time).
Suitable for projects which require long-range reading, such as vehicle’ management, warehouse management, garments sorting, logistic tracking, etc.
Correspondently, there are 3 types of RFID readers to read and write the 3 different types of RFID card and tag; NFC card and tag should be read/ written by an NFC reader.
P.S.: Anice also provides basic RFID and NFC devices (RFID reader, RFID UHF antenna and NFC reader) to fit clients’ requirements.
IMPORTANT NOTICE:
There are many different chip types with the same frequency and protocol, and they are not completely compatible with the system, also, price differs a lot for different chips. So, if you are not sure which chip you are using, we are happy to receive a sample card for testing.

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

Simple demonstration on how to use a RFID card, door card for example.
Each RFID chip has a unique ID number when manufactured, system will store and authorize this ID number so that when you use this card to open a door, the system will give an order to the lock to open it.
Some are more complicated that you might need to encode or encrypt some certain data inside the chip, only when the system recognized full information in the right sector and right block, it will give an order to the lock to open the door, which could improve the security to a higher level.
Data encoded in the RFID or NFC chip
Data detected and transmitted to the system
Data identified, system unlocks the door.
Door opens successfully
How about NFC card? NFC business card for example:
Write your contact information inside the NFC chip with an NFC smart phone (you will need an app named “tag writer”), tap the card with an NFC phone, and your information will be fully presented on the screen. You can also write URL, text, SMS inside the chip.
Short reading range, around 5 cm;
Readable and writable;
Available for encryption;
Signal could be influenced by metal, regular data speed;
Can read one NFC tag only at one time;
Normally used for payment or anti-counterfeiting.
If you need to print personalized information on the card, an overlay is necessary in order to ensure the best printing effect. Also, please kindly inform us which part you need to print in advance so that we can adjust the chip position.

Nexqo provides hybrid (dual frequency) RFID cards, common combination could be as follows;
1.LF + HF/NFC
2.HF/NFC + UHF
3.LF + UHF
4.LF/HF/NFC/UHF + magnetic stripe
Usually, HF and NFC will not be combined into one card because they are the same frequency, you might be confused by which chip is actually being detected.
