How to choose NFC chip and design NFC tags?

2017-7-21 View:
"First: Check the Chip is compatible with your NFC Device.
Ultralight, Ntag203,,Ntag216 and Topaz512 all are universal chip and compatible with all NFC Mobile devices.

Second:Select the chip memory Select the chip memory storage ability you need
Ntag216 is the newest chip which has highest memory storage (888 Bytes). Due to higher memory Ntag216 can also store complete vCard.

Topaz512 Chip has more user memory (454 Bytes) than Ntag203 and Ultralight chip.

If you are not sure whether you would need more than 144 Bytes or not, then you should certainly select Topaz512 as a safe side.

Ultralight is having very less memory. Though it is having 48 Bytes user memory, it can store only 41 characters as 7 bytes is used as unique id number of the chip. However Ultralight is used in specific application due to its cost effectiveness.

Fourth: desing NFC tags size and shape
Performance remains almost same for different shapes.
Size decides the scanning distance – Larger size antenna can scan data from longer distance for particular smart phone. Note that scan distance mostly depends on smart phone’s inbuilt NFC Hardware.

        A smart card is a small plastic card containing a computer chip. People use smart cards along with personal identification numbers (PINs) to log on to a network, a computer, or a device. Using a smart card is more secure than using a password because it's more difficult for someone to steal a smart card and learn your PIN than to learn your password.Smart cards are generally issued by information technology (IT) departments in large organizations. To use a smart card, you also need a smart card reader—a device that’s installed in or connected to your computer and that can read the information stored on a smart card.
