NFC & BLE

NFC Hardware used for ACCESS control

NFC Shield

MFRC522

ISO 14443A, ISO 15693 & Felica cards are used here. These are all passive NFC tags (devices). These cards / reader run @ 13.56 MHz in close proximity (~10cm) with a reader antenna. Tags are pre-configured at manufacture to be either read and re-writable, or read-only.

NFC Forum Tag Type Technical Specifications

Type 1 Tag is based on ISO/IEC 14443A. Tags are read and re-write capable; users can configure the tag to become read-only. Memory availability is 96 bytes and expandable to 2 kbyte.

Type 2 Tag is based on ISO/IEC 14443A. Tags are read and re-write capable; users can configure the tag to become read-only. Memory availability is 48 bytes and expandable to 2 kbyte.

Type 3 Tag is based on the Japanese Industrial Standard (JIS) X 6319-4, also known as FeliCa. Tags are pre-configured at manufacture to be either read and re-writable, or read-only. Memory availability is variable, theoretical memory limit is 1MByte per service.

Type 4 Tag is fully compatible with the ISO/IEC 14443 standard series. Tags are pre-configured at manufacture to be either read and re-writable, or read-only. The memory availability is variable, up to 32 KBytes per service; the communication interface is either Type A or Type B compliant.

NFC LoRaWAN Device with LoRaWAN extending its range to 30km

Near Field Communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within (~5cm) of each other.

HF RFID ISO 14443A, ISO 15693 & Felicia cards are used here. These are all passive NFC tags (devices). ISO/IEC 15693 systems operate at the 13.56 MHz frequency, and offer maximum read distance of 1–1.5 meters Tags are pre-configured at manufacture to be either read and re-writable, or read-only.

Quote from Estimote site "The greatest advantage of Bluetooth Smart over the previous iterations of BT technology is how energy efficient it is. Thanks to that, and to a lot of work our engineers put into power management, Estimote can last more than 3 years on default settings on a single CR2477 battery."
