NFC/RFID

RFID (Radio Frequency Identification) is a system composed of a radio transponder, receiver and transmitter. By trigging an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This technology helps the device read the information contained in a wireless device or tag from a distance without making any physical contact or requiring a line of sight. Passive RFID systems use tags that are powered by electromagnetic energy from an RFID reader without any internal power source, therefore have the advantage of requiring non-batteries and are more economical in price. It is widely used for applications such as supply chain management, human tracking, access control, and smart labels.

RFID UID Reader is the basic function in all RFID modules that can read information from the RFID tag UID (unique identifier) to a verify a user's identity and grant access. UID reader RFID module helps designers can shorten the project schedule by solving signal fine-tuning and optimization issues.

RFID Encryption is used for encrypting user data stored on identification tags. With an encryption key unique on the tag identification of each tag, only a specific unique key can used to encrypt data for storage on the corresponding tag or to decrypt encrypted user data stored on the tag. It helps improve connection security because data transfer between tags and trusted readers could be encrypted so that any rogue readers can't intercept the message.

Replacing the traditional RFID entity sensing card, the Apple Wallet VAS and Google SmartTap pass can work over a short distance and can be used to present contactless passes independently with only user's phone. When the device is held near the NFC terminal, the terminal will initiate receiving the pass information by sending a request for a pass, therefore the users can easily integrate keys, tickets, gift cards or loyalty cards by just tapping their phone. This technology guarantees higher security by encrypt the transaction process and complete it in code.

UHF (Ultra-High Frequency) RFID reader uses a frequency band between 840MHz to 960 MHz. It has a much more reading range compared to HF NFC readers and can enable one reader to interact with numerous tags at the same time. The UHF RFID reader is multi-purpose for long RFID application RFID application fields such as ETC (Electronic Toll Collection System) or inventory management.
