At the heart of every NFC tag, sticker or product is an NFC 'chip' or 'IC' (integrated circuit). These tiny electronic devices store your information and control how it can be accessed.
Different NFC chips have different sizes of memory and different memory configurations. This affects the amount of information you can store on certain chips but it also affects how the chip can be locked and other very important factors.
RapidNFC only stock products containing chips manufactured by NXP Semiconductors. These are market leading, industry standard IC's.
RapidNFC stock tags and products containing a number of different NFC chips including the NTAG203, Ultralight, Mifare 1K and Topaz 512 chips. The table below should give you some idea of which is best for your needs. For more information on each item, scroll down the page.
Of course, if you aren't sure what's best for your application, then don't hesitate to contact us.

Then get in touch, we are always happy to give advice and help.
As a general bit of advice, we'd usually recommend that you go for the NTAG203. If you are using a Task Launcher app, then NTAG203 works great. If you need a product (such as a wristband or keyfob), then Ultralight is your next best option. The next generation chips (NTAG210 and NTAG213) are currently only recommended for development or where the use of the additional features (scan count, UID mirror, password protection) is required.
