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 genuine chips manufactured by NXP Semiconductors and Broadcom. These are market leading, industry standard IC's. We do not use the cheap copies in any of our products.
RapidNFC stock tags and products containing a number of different NFC chips including the latest NTAG213, MIFARE Ultralight®, MIFARE® Classic 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.

|Best Use||Cost effective chip for short URLs in products (wristbands, keyfobs, etc).||No longer made, this was a popular all-round NFC chip. Replaced with the NTAG213.||Cheap, general NFC use with short URLs. Limited availability.||The most popular NFC chip. Great value and strong Scan-Strength||The 'one in the middle'. Good memory but limited availability compared to the NTAG216.||Large memory and full feature set. Higher price makes it suitable for vCard and larger memory use only.|

|32 bit Password||No||No||Yes||Yes||Yes||Yes|

|ScanStrength 8||High||High||High||Very High||High||High|
** There is now a 'next generation' version of the MIFARE Ultralight called the MIFARE Ultralight EV1. The usable memory capacity is the same but the new EV1 chip has simple 32bit password protection, an originality signature and counters like the NTAG21x series. (Note that the counters don't have a 'mirror' function like the NTAG21x series so the count cannot be placed dynamically into a web address.)

|Best Use||Specialist applications requiring encryption only. Poor scan distance with mobile phones.||Legacy applications only. Not recommended for general mobile phone NFC usage.||Specialist applications requiring strong data encryption only.||Universally compatible chip available in only a limited number of products. Useful for vCards or small data storage.|

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 products with NTAG213 chips. If you are launching a website or using Trigger type App, then NTAG213 works great. If you need a product (such as a wristband or keyfob), then MIFARE Ultralight is a great option and ideal for identification purposes.
