    • BitCauses Bringing anonymous charitable donation into the modern era with Bitcoin and NFC technology Chris Raggio MD
    • My Background B.S. Computer Science Software Developer Biomedical Informatics M.D. Doctor of Medicine Psychiatry Care for indigent patients diagnosed with Severe and Persistent Mental Illness
    • Financial Resources are critical to providing care • Availability of Financial Resources or lack thereof has a significant impact on patient care. Vicious Cycle Emerges. • Loss of Employment • Loss of Transportation • Loss of Housing • Loss of Access to Medications when treatment is no longer affordable
    • http://www.who.int/mental_health/policy/development/1_Breakingviciouscycle_Infosheet.pdf
    • Efficient High Impact Fundraising • • • • • • Desirable characteristics include Work across geopolitical boundaries Frictionless Provides high degree of transparency Inexpensive to deploy Allow microtransactions Anonymous - donors cannot be identified
    • Near Field Communication in a nutshell NFC protocol is an extension of RFID RF Communication occurs at 13.56 MHz NFC uses magnetic induction Applicable standards include ISO/IEC 14443 Allows for smartphones and other devices to communicate wirelessly in proximity • Smartphones can communicate with a “tag” or proximity “card.” • PCD (phone) read/writes PICC (tags) • Card Emulation mode • • • • • Source: http://en.wikipedia.org/wiki/Near_field_communication
    • Uses of NFC include • Matching encrypted security code and transporting access key; • Due to short transmission range, NFC-based transactions are possibly secure; • Instant payments and coupon delivery using your handset, as we do with your credit card or debit card; • Marketing and exchange of information such as schedules, maps, business card 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 smart stickers in retail stores • Scavenger hunt gameplay for validating hidden objects using smart phones Source: http://en.wikipedia.org/wiki/Near_field_communication
    • MIFARE Classic 4K • • • • The MIFARE Classic card is fundamentally just a memory storage device, where the memory is divided into segments and blocks with simple security mechanisms for access control. They are ASIC-based and have limited computational power. Thanks to their reliability 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 allow operations such as reading, writing, increasing value blocks, etc. MIFARE Classic 4K offers 4096 bytes split into forty sectors, of which 32 are same size as in the 1K with eight more that are quadruple size sectors. MIFARE Classic mini offers 320 bytes split into five sectors. For each of these card types, 16 bytes per sector are reserved for the keys and access conditions and can not normally be used for user data. Also, the very first 16 bytes contain 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 security protocol (Crypto-1) for authentication and ciphering. The Samsung Tectile nfc tag stickers use Mifare Classic chips. This means, only devices with an NXP nfc controller chip can read/write these tags. At the moment BlackBerry phones and the Nokia Lumia 610 can't read/write Tectile stickers (August 2012).[2] MIFARE Classic encryption has been compromised, see below for details.

    • BitCauses Charity poster • Poster has two NFC tags. The first tag when scanned takes the potential donor to a charity’s web site • The second tag is a rewritable NFC tag or card. Donor writes a donation in the form of a offchain transaction directly to the tag. Transaction can be encrypted with public key from charity. URI would prompt donor with request for funds. Transaction would occur off chain.
    • Bitcoin needs political capital • BetaBeat Chuck Schumer Bashes BitCoin, Wants to Shut Down Silk Road Drug Site By Ben Popper 6/06/11 11:55am • Bitcoin Magazine Mitt Romney Blackmailed for Bitcoins Vitalik Buterin September 6, 2012.
    • Ways to Conduct Transaction • Transfer coins on the block chain • Donate a private encrypted with public key from charitable organization • Off-Block Chain Transaction http://gavintech.blogspot.co.uk/
    • Bitcauses Needs Volunteers • Code • Graphic Design • Legal • Marketing • Anyone who wants to help Please contact me if interested BitCauses.org
