For many years the barcode has been the quintessential object identification system, but everything indicates that this old acquaintance has the days counted.

Radio frequency self-identification (RFID) technology is pushing hard and has already begun to shift to the barcode. The emerging system allows remote objects to be identified by electronic labels. It offers multiple advantages and is a solution to many problems not solved so far. XINYETONG will help you fully understand RFID Smart Cards through 5 FAQs on

How does RFID work?

For RFID technology to work, three basic elements are necessary: ​​an electronic card, a card reader and a database. Smart cards carry a built-in microchip that stores the unique identification code of the product to which they are attached. The reader sends a series of radiofrequency waves to the card, which it picks up through a small antenna.

These waves activate the microchip, which, through the micro-antenna and radiofrequency, transmits to the reader what is the unique code of the article. In short, a reading team sends an interrogation signal to a set of products and they respond by sending each one their unique identification number. For this reason, it is said that RFID technology is a self-identification technology.

Once the reader has received the unique product code, it transmits it to a database, where the characteristics of the article in question have been previously stored: expiration date, material, weight, dimensions. This makes it possible to consult the identity of merchandise at any time and easily throughout the supply chain.

Is it profitable for any company to use RFID?

To quantify the return on investment in RFID, it is essential to first identify the sources of value of this technology.

Among its many advantages, RFID allows real-time monitoring of products, which facilitates the permanent availability of merchandise at the point of sale, synchronization of supply and demand (with the consequent reduction in inventory), efficient expiration or expiration management (key to fresh products), prevention of loss and theft (which represents 2 to 10% of total merchandise), and improvement of customer service and as a consequence, Your loyalty Regarding this last point, being wireless, RFID technology allows you to charge a customer's purchase without having to take the products out of the cart. In this way, the collection time is reduced, which can translate into greater customer turnover.

Some examples of the practical application of RFID technology are:

1. Input and output control.
2. Tracking of sending letters, documents, parcels.
3. Quality controls and factory production chain.
4. Search for bottlenecks or asset protection in a company.

Largest people don't even know what RFID is but probabilities are they have already been affected by it. You have or are about to own an RFID tag and you don't even recognize it.

Contactless smart ID cards have been in the market for many years, although it seems the latest in the sector for those who are barely getting acquainted with them. However, its permanence in time speaks very well of its usefulness; becoming even necessary in different everyday environments.

The Electronic Chip incorporated in the contactless smart card is capable of storing the necessary data for identification and authentication, sometimes adding other functions such as added value.
