Near Field Communication in a nutshell

NFC protocol is an extension of RFID

RF Communication occurs at 13.56 MHz

NFC uses magneticinduction

Applicable standards include ISO/IEC 14443

Allows for smartphones and other devices tocommunicate wirelessly in proximity

Smartphones can communicate with a tag orproximity card.

Uses of NFC include

Matching encrypted security code and transporting access key;

Due to short transmission range, NFC-based transactions are possiblysecure;

Instant payments and coupon delivery using your handset, as we do withyour credit card or debit card;

Marketing and exchange of information such as schedules, maps, businesscard and coupon delivery using NFC Marketing tags

Pay for items just by waving your phone over the NFC capable devices

Transferring images, posters for displaying and printing

Social media e.g. Like on Facebook, Follow on Twitter via NFC smartstickers in retail stores

Scavenger hunt gameplay for validating hidden objects using smart phones

MIFARE Classic 4K

The MIFARE Classic card is fundamentally just a memory storage device, where thememory is divided into segments and blocks with simple security mechanisms for accesscontrol. They are ASIC-based and have limited computational power. Thanks to theirreliability and low cost, those cards are widely used for electronic wallet, access control,

corporate ID cards, transportation or stadium ticketing. The MIFARE Classic 1K offers 1024 bytes of data storage, split into 16 sectors; each sector

is protected by two different keys, called A and B. Each key can be programmed to allowoperations such as reading, writing, increasing value blocks, etc. MIFARE Classic 4K offers4096 bytes split into forty sectors, of which 32 are same size as in the 1K with eight morethat are quadruple size sectors. MIFARE Classic mini offers 320 bytes split into fivesectors. For each of these card types, 16 bytes per sector are reserved for the keys andaccess conditions and can not normally be used for user data. Also, the very first 16 bytescontain the serial number of the card and certain other manufacturer data and are read

only. That brings the net storage capacity of these cards down to 752 bytes for Classic 1k,3440 bytes for Classic 4k, and 224 bytes for Mini. It uses an NXP proprietary securityprotocol (Crypto-1) for authentication and ciphering.

The Samsung Tectile nfc tag stickers use Mifare Classic chips. This means, only deviceswith an NXP nfc controller chip can read/write these tags. At the moment BlackBerryphones and the Nokia Lumia 610 can't read/write Tectile stickers (August 2012).[2]

MIFARE Classic encryption has been compromised, see below for details.
