“NFC” stands for ‘Near Field Communications’. NFC technology enables a close proximity, 4cm, wireless transfer of small amounts of data from a passive (battery-less) tag to a powered reader such as a cell phone.
Q
What is RFID?
A
Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information. Some tags are powered by and read at short ranges (a few meters) via magnetic fields (electromagnetic induction). Others use a local power source such as a battery, or else have no battery but collect energy from the interrogating EM field, and then act as a passive transponder to emit microwaves or UHF radio waves (i.e., electromagnetic radiation at high frequencies). Battery powered tags may operate at hundreds of meters. Unlike a bar code, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object.
Q
What do I do if I don't have an RFID or NFC enabled device?
A
Every Tap2Tag device has a unique code printed on it. If you do not have an RFID or NFC enabled device to scan the tag then you can go to www.tap2.me mobile site and enter the code printed on the device. Just follow the instructions on the screen.
Q
Will Tap2Tag work with my iPhone?
A
Apple have currently tied down their NFC chip so it only works with their ApplePay payment system. However, with the IOS11 update, iPhone users can now use their camera to scan the QR code printed onto our newer devices.
Alternatively the first responder can still access the medical/pet/connect information by following these instructions.
1. Just open up Safari
2. Go to www.tap2.me
3. Enter the 9 letter code printed on the device
Not quite as quick as a tap but equally as effective. And now we have heard some interesting news coming out of Apple. You can read the full story at https://www.tap2tag.me/news/apple-to-support-nfc/
Q
Why did Tap2Tag choose NFC over other technologies, like RFID?
A
Tap2Tag chose to use NFC over RFID because of the needed close proximity to activate the NFC tags. This feature allows us to use the same high levels of security that you have come to expect from your credit or debit cards.
Q
What is the difference between NFC and RFID?
A
RFID is the process by which items are uniquely identified using radio waves, and NFC is a specialized subset within the family of RFID technology. Specifically, NFC is a branch of High-Frequency (HF) RFID, and both operate at the 13.56 MHz frequency. NFC is designed to be a secure form of data exchange, and an NFC device is capable of being both an NFC reader and an NFC tag. This unique feature allows NFC devices to communicate peer-to-peer. [1]
