"Discover the Power of ReadPi - The RFID/NFC Reader Powered with Raspberry Pi Pico W!"

 A new Kickstarter campaign for the appropriately called ReadPi is expected to pique the curiosity of developers, amateurs, and Raspberry Pi aficionados looking for an RFID or NFC reader powered by a Pico W. The ReadPi, which is now in its last week of financing, has already blown over its minimum contribution target with four days left. It contains a 125 kHz 13.56 MHz frequency, a 1.3-inch LCD screen, an SD card reader, a buzzer, a joystick, and battery support. Early-bird contributions for the innovative initiative start at about $33 or £28. (depending on current exchange rates).

It has two versions: ReadPi 125 KHz frequency (Read Only feature) and ReadPi NFC 13.56 MHz frequency with NFC. ReadPi is an RFID reader that is driven by a Raspberry Pi Pico W. (Read and Write feature). Both variations operate wonderfully in a real-world setting. The ReadPi works by utilizing radio waves to recognize a particular RFID tag. As a result, the reader generally produces a 125KHz frequency through its coils, and if a passive RFID tag operating at that frequency is present, it is powered. The CMOS IC in the tag, on the other hand, will make sure that the tags are powered continuously.

The tags will utilize and send this information as storable data in a programmed memory as soon as they learn they are operating at the same frequency as the reader. This will enable the reader to recognize it right away. Radio waves are used in RFID (Radio-Frequency Identification), a wireless technology, to detect the presence of RFID tags.

The ReadPi crowd fundraising effort is aiming to gather the requisite amount of pledges, and if all goes according to plan during production, the international shipment should start around March 2023. Watch the below promotional video to learn more about the ReadPi Raspberry Pi NFC reader project.

"To aid with comprehension, think about using a bar code reader. Similar to how they do it in supermarkets, you must optically scan the bar in front of a scanner for it to work. With RFID, however, you do not need to monitor anything as long as it is inside the RFID's transmitting radio wavelength. The ReadPi functions as both a reader and a tag in the RFID system. Within a certain radiofrequency range, it immediately scans and reads ID tags. The RFID reader has antennae and a stationary transceiver for signal reception. Therefore, the reader will recognize an ID if it falls inside a particular range and send the information to the microcontroller or PC.
