RFID / Radio frequency identification

RFID ("radio frequency identification") is a technology that can transmit information even without its own power source when it comes close to a reading unit.

RFID technology plays a significant role in the world of trade, warehousing and logistics. Its physical appearance is usually a label, stamp or sticker placed on or in an object. The essence of its operation is that we can store a relatively large amount of information condensed into a single sticker and transfer it to a computer system every time the sticker is near a scanning unit.

One of the most useful features of the solution is that the sticker does not need its own energy source to communicate with the scanner, the sticker obtains the necessary energy from the electromagnetic waves emitted by the scanner. At the same time, there are also semi-passive, very low power and active RFID systems. Even the former are able to collect and store information from the sensors in their environment, and the latter send and receive signals at much greater distances, even with enough "fuel" for years.

Storage, logistics and commercial systems based on the use of RFID, access gates, safety signaling devices or bracelets can now be found in almost every store and wellness center, but this type of identification is also revolutionizing operations in many other areas. 

It is enough to think about the benefits of connecting the systems that register the patient's condition with patient journeys. If we supplement this with information available from wearable devices (heart rate, blood sugar or blood oxygen measuring devices), the diversity of use becomes clear. It is considered RFID technology NFC also, which allows it to be smartphones tactile as a means of payment we use it.
