Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other

NFC is faster than Bluetooth (424 kbps ), and it can be used to induce electric currents within passive components as well as just send data.

You can get three different facility or modes of operation from NFC
  • 2 smartphone to swipe data
  • Read or write mode, a active device can pick up information from passive device
  • It will work as a contact less card
A contactless smart card is a contactless credential whose dimensions are credit-card size. Its embedded integrated circuits can store (and sometimes process) data and communicate with a terminal via NFC.

To be slightly more precise. Contactless refers to a range of technologies using RF (Radio Frequency) to communicate between a terminal and another device (often a card). It is most often used to refer to products around the ISO 14443 and ISO 15693 standards, which both use a 13.56Mhz frequency, but people will use it for other devices and frequencies.

NFC (Near Field Communications hardware is a set of specifications published by the NFC forum, based on ISO14443 and ISO 18092 which also work at 13.56MHz but with the particularity of using the technology both ways round. So integrated into a phone NFC can be used to make the phone behave like a contactless card (called card emulation) or as a card reader. By extension many people refer to cards and terminals that can do one half (using ISO14443) as NFC Cards or NFC Readers.

To wrap up Contactless is a more generic term covering several technoloical standards, NFC refers to a precise set of specifications, they are pretty closely related but both terms are used with varying amounts of precision.
Thus java programming is play a important role in this process.

The Radio-frequency identification (RFID) is a technology which is working on radio frequency of radio waves. and it also is a technology similar in theory to bar codes.

RFID uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically-stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source (such as a battery) and may operate hundreds of meters from the RFID reader.

So whenever this object is in the range of the reader then this RFID tag used to transmit its feedback signal to the reader. And it is very similar to the technology which is used in a barcode.
