The NFC Forum chose the initial tag formats to cater for the broadest possible range of applications and device capabilities. |
|
|
|
With four NFC Forum-mandated tag types to choose from, designers need to consider carefully the relative merits of each before committing to one type or another. With initial mass-market deployments likely to be in low-financial value, low-risk applications, it is important that NFC tags meet the requirements with the right balance of cost and performance. There will also be more specialist applications that require greater tag capabilities, and that are less sensitive to cost and size considerations. |
