rfid distance sensor arduino Arduino: Wiring and Programming of RFID Sensor. RFID, or Radio Frequency Identification, is a system for transferring data over short distances (typically less than 6 inches). Often only one of the two devices needs to be powered, while the other is a passive device.
Contactless credit cards are cards that don't require you to insert your card chip when you make a purchase. These cards use EMV chip technology (chip security developed for Europay, Mastercard and Visa but now used by many cards) with NFC (near-field communication) for proximity payments.

I understood that all methods to get distance from RFID are more or less at a . I'm trying to make a long-range RFID reader which could read 13.56MHz . I understood that all methods to get distance from RFID are more or less at a “research” level. (is it still true ?) I know 2 of these methods: The “RSSI method”, that measure the signal strength, and the “radar” method, that measure the time between signal emission and Tag answer reception. I'm trying to make a long-range RFID reader which could read 13.56MHz passive RFID tags at a minimum distance of 1m. I'm planning to use an Arduino Uno for this purpose. But I'm not sure of what reader module should I use.

Arduino: Wiring and Programming of RFID Sensor. RFID, or Radio Frequency Identification, is a system for transferring data over short distances (typically less than 6 inches). Often only one of the two devices needs to be powered, while the other is a passive device. There are many kinds of RFID, for this I think you'd want an active tag, and the UHF tags (850-900MHz) can be read from a distance using a directional antenna. You don't switch to different readers. http://www.thingmagic.com/rfid-basics. "Near field UHF RFID tags contain a small silicon chip and an antenna paired onto or into an object.

In short, if you want to power the tag at distance, think big coil and think litz wire and think parallel tuning for maximum efficency. The power receive coil was also very low loss and highly tuned to get as much voltage as possible when set at the maximum distance. RFID uses electromagnetic fields to transfer data over short distances. RFID is useful to identify people, to make transactions, etc. You can use an RFID system to open a door. For example, only the person with the right information on his card is allowed to enter. An RFID system uses:
In this beginners guide, you will learn how to connect an RFID reader module to an Arduino Uno and read tag information from RFID cards and tags. We will go over the components needed, how to wire up the circuit, example Arduino code to interface with the reader, and testing procedures.The RC522 module works on a 13.56 MHz frequency and it can act as a reader and write for UID/RFID cards. The RFID cards communicate with the module at a short distance with radio frequency due to the mutual induction technique.Arduino/ESP32 code for R200 long-range UHF RFID reader. The R200 is a UHF RFID module based on the EPC Gen-2 (ISO18000-6C) protocol. What does that mean in practice?
