![]() ![]() It may sound like a big flaw for NFC, but this is exactly what makes it more secure than RFID. NFC works at a lower speed than RFID and can only operate within a 4-centimeter range. You can also compare it with other networking technologies such as Bluetooth and Wi-Fi. NFC or near field communication is a type of radio communication standard like RFID. Given all these developments, you may be wondering: Is it really safe to use NFC technology? If so, then how does it guarantee security? They are now widely used to make payments, provide door access, and other applications that concern personal data or assets. NFC tags have become pretty common these days. Some companies also customise your metal card with the NFC chip of your choice. Be sure to get NFC chips from reputable sources, so you’re assured of their quality and authenticity. That makes it practical for short text strings or links. It is more advanced than the classic version, but with limited memory of around 46 bytes. Mifare Ultralight – A chip that works with Android and iOS devices. ![]() ![]() It supports encryption and is compatible only with newer iOS and Android smartphones. Mifare Classic – Use this 716-byte chip only if you’re already using a Mifare-based protocol system, or if your tags won’t be used by the general public. Here are the different types you can find today: If you don’t require maximum compatibility, consider NXP Mifare chips. It’s fast but costs significantly higher than other NFC chips. NTAG216 – An NFC chip with the highest capacity at 888 bytes for metal business cards with full V-card data. It comes with password protection, a common feature in all NTAG21x. NTAG215 – This NFC chip has a 504-byte memory ideal for encoding with V-cards or additional data. Besides the enhanced performance, its memory is slightly bigger at 144 bytes, and it’s reasonably priced. NTAG213 – The new version of the NTAG203 with better range and speed. Every option has slightly more memory and may cost slightly more than others. You’ll find NFC chips developed by NXP Semiconductors known as NTAG213, NTAG215, and NTAG216 chips. Here’s a guide to help you with the selection. There are different types of chips available, so it can get confusing to make an informed choice. The correct NFC chip will make your metal card more functional and practical with all NFC-equipped smartphones and tablets. They are customisable by laser engraving and NFC chips, which come in different configurations to suit your specific requirements. NFC metal cards provide the perfect way to make a memorable impression each time. ![]()
