Here are some things I've considered: Ditch the embedded antenna on the cheap RFID reader and construct my own, larger antenna. I'd need to see if the onboard MFRC522 is up to the task of providing additional power. Look for a different IC around which to build a reader .Is it possible for an Android application to send a previously stored RFID card ID to a NFC .

The aim would be to use an Android device to enable access to a room instead of a physical RFID card.
I want to know if there is any open source code that is available to boost proximity card signal. I have the card and the reader is in my office. I would just like something to boost the signal of the card from within my car so the reader can read the card (atleast about 1.5 feet away). Sensor data can be wirelessly transmitted from simple, battery-less tags using Radio Frequency Identification (RFID). RFID sensor tags consist of an antenna, a radio frequency integrated.This reflection amplifier consumes 0.2 mW DC power at bias voltage of 200 mV, making it an ideal candidate to amplify backscattered electromagnetic field in RFID transceivers. The gain of the proposed reflection amplifier is 17 dB for the incident power of -30 dBm.A great challenge in UHF RFID systems consists of increasing their operating range. In this work, a circuit topology consisting of a reflection amplifier and a passive coupler is proposed to both amplify the input signal to the tag as well as the backscattered signal towards the reader.
All RFID readers have the ability to control how much power they send through the cables to the antennas. Check your reader’s settings to see how much transmit power you are transmitting (in dB); the higher the number, the more you'll increase read range, and vice-versa.
Chipless RFID, also known as passive RFID sensors, are compatible with planar technology, allowing them to be produced by roll-to-roll processing. RFID sensors are a new paradigm for the internet of things (IoT).
The aim of the present paper is to review the main technologies available for RFID sensors, and to identify the corresponding state-of-the-art when these technologies are applied to realistic IoT scenarios. The CRFID tag is used as a communication interface for transmitting data. Passive RFID sensors harvest the RF energy from RF radiation to power the circuit, perform the sensing task, and save the data in the RFID chip to be accessed by RFID readers.
