Your existing WeWork access card will still work to open doors in the office. View Article. . Apple Pay works by automatically detecting NFC readers, like the ones that read access cards, so unfortunately the wallet pops up whenever the .
For the majority of tags likely to be experimented by Hackaday readers the RF frequency is 13.56 MHz, and the RF emissions are supposed to be in the magnetic field plane . See moreMost tags, and the cheapest reader modules, have very little effort put in to tuning them to resonance, but one of the more interesting tags I examined for this piece, a bank card subjected to a teardown by a hackerspace friend, shows a very clever . See moreTurning to the readers, the more expensive devices have a built-in variable capacitor and will have been factory-tuned to 13.56 MHz, while the cheap modules normally have a fixed capacitor and resonate at a higher frequency. Experience with . See moreWondering how to select near-field communication (NFC) readers for your IoT system .

This module can be read by a card reader, but only when it is placed directly on the antenna rather than with any part of the whole card in proximity to the reader as would happen in a shop.Wondering how to select near-field communication (NFC) readers for your IoT system development? From choosing the right NFC chip to a successful implementation, this third part of our NFC technology blog series, is full of pro tips to get you started.This standard limited the read range to a few inches in order to prevent eavesdropping on tag-to-reader communication. More recently, NFC has incorporated the ISO 15693 standard, which offers a maximum read range of about 3 feet.
Raise the gain as much as possible. This will boost the tag signal on the reader side but will boost any noise as well. Adjust the threshold until you get reliable communication at your target distance. With a modern reader chip you should be able to get about 20cm of reading distance against ISO14443-A tags. And now the drawbacks:
So the challenge in NFC antenna design is to obtain a "radiating" structure when the NFC antenna area may be limited to 3"x1" (or 7 cm * 2.5 cm). Hence, we are talking about fitting an antenna into a volume where the maximum linear dimension is about 0.5% or less of . When using a NFC standard loop coil antenna, sized about 4x4 cm, the theoretical maximum working distance is 20 cm. In practice, the range for reliable communication is much smaller, usually about 5 cm (4 times smaller). In general, the larger your antenna size, the longer the reading distance. Similarly a smaller antenna will give you a shorter read range. However, it’s best to attempt to match the tag and the reader antenna geometries for maximum efficiency. Tag and reader IC selection can also impact read range.

As for recommendation, with smartphones as readers, I think there is no need to go with a tag antenna size larger than class 1 (credit card size antenna 50x80mm). With smartphones, larger antenna will provide any benefit because the phone antenna size are usually smaller than that.Software example written for Lazarus/FPC.

Tested on Windows and Linux-RPI.NFC FPC Antenna AANI-FB-0028 Packaging 1. 50 pcs in a PE bag 2.
