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 Ultralight, Ultralight C, Standard (Classic) 1K, Desfire 4k and the new NTAG203 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.

1 - Memory Size
: this is the total amount of memory within the chip. Some of this will be one time programmable (OTP), some will be for locking features and so on. Most will be for user read/write.2 - User Memory
: this is generally the bit that's important to you. This is the available memory for you to store your data.3 - URL Length
: this is generally the maximum length of URL you can store on this chip, excluding
the http:// or http://www parts
4 - Text Length
: this is generally the maximum length of plain text you can store on the chip.
5 - Mobile Compatability
: if you are using an Android App to self-encode your NFC tags, then certain locking features will not work with the 1k. Since Mifare 1k tags follow a proprietary format, they are incompatible with BlackBerry devices, which read only approved open standard tags defined by the NFC Forum.
6 - NFC Forum Type 2
: Compatible with NFC Forum Type 2 specifications.
7 - Serial Number
: Chip contains a unique serial number for identification purposes. Note that a specific 'App' would be required to access this information.
8 - Cryptography
: A security feature on the chip which can help prevent cloning. This is a very advanced feature which requires specialist knowledge and is rarely required under regular use.
8 - ScanStrength
: The average RapidNFC ScanStrength of current products sold on RapidNFC. This is an indication of the relative scanning distances of the chip. More information on ScanStrength.
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.
