Blockchains.my is a decentralized mobile wallet developed using blockchain technology and the advanced security of biometric identification systems. It is a platform that simplifies the process of making payments, as well as trading and exchanging digital currencies and gold among users with a real-time price monitoring facility. The wallet is integrated with a debit card, as well as a NFC (Near Field Communication) Smart Card to create an association between the conventional financial service and the cryptocurrency market.

NFC Smart Card

An NFC Smart Card is a contactless payment card. Its embedded integrated circuits can store and sometimes process data, and communicate with a terminal via NFC – a wireless communication technology that allows data to be exchanged between devices that are a few centimeters apart. Commonplace uses include transiting tickets and passports. There are two broad categories of contactless smart cards. Contactless smart cards contain read-only RFID called CSN (Card Serial Number) or UID, and a rewritable smart card microchip that can be transcribed via radio waves. Contactless smart cards can be used for identification, authentication, and data storage. They also provide a means of affecting business transactions in a flexible, secure, and standard way with minimal human intervention. A quickly growing application lies in the digital identification cards. In this application, the cards are used for authentication of identity. It is usually used in conjunction with a Public Key Infrastructure. The smart card stores an encrypted digital certificate issued from the PKI along with any other relevant or needed information about the card holder. When combined with biometrics, smart cards can provide two or three factor authentication

History

Contactless smart cards were first used for electronic ticketing in 1996 in Hong Kong. Since then, smart cards with contactless interfaces have been increasingly popular for payment and ticketing applications such as for mass transit. Globally, contactless fare collection is being employed for efficiency in public transit. The various standards emerging are often local in focus, and not accepted in the external markets, though the MIFARE Classic card from Philips has a large market share in the United States and Europe. In more recent times, Visa and MasterCard have agreed to standards for general “open loop” payments on their networks, with millions of cards deployed in the USA, Europe, and around the world. Smart cards are being introduced in personal identification and entitlement schemes at regional, national, and international levels. Citizen cards, drivers’ licenses, and patient card schemes are becoming more prevalent. In Malaysia, the compulsory national ID scheme MyKad includes 8 different applications and is rolled out for 18 million users. Contactless smart cards are being integrated into ICAO biometric passports to enhance security for international travel.

Applications For Near Field Communication

1. Smart Cards

Payments using NFC integrated smart cards are relatively easier compared to conventional multi-step payment processes. Top payment services like Visa and MasterCard are offering NFC embedded smart cards to customers. NFC integrated smart cards can be used for fast payments at grocery shops, parking tickets, adding shopping points, and redeeming coupons with just a single tap of the card.

2. E-wallets (Enabling Payments Using Smartphones)

Cashless payment systems using mobile devices became popular in the beginning of this decade and more services are offering cashless payments for customers’ convenience. Using smartphone applications, payments can be made using a simple tap or a wave of the card within close proximity to the reader. Service providers can integrate payment options into smartphones using an NFC tag embedded inside the device. Apple Pay, Google Wallet (Android Pay) and Samsung Pay are the most popular among Smartphone payment systems to date, with many others to choose from, like our BCMY wallet. Data transfers using smart devices are possible using NFC technology like Android beam.

3. Smart Ticketing

Integrated smart chips can be used to replace traditional ticketing systems with smart tickets for airlines, trains, and bus tickets, etc. NFC tags can be used for smart posters, movie tickets, advertisements, flyers, and information links. Customers will be able to access a reserved area or activate their tickets just by tapping their NFC tags located at assigned locations. More information can be found by just scanning the smart tag.

4. Medicine and Healthcare

NFC integrated systems can be used in medicine and healthcare activities. NFC offers greater accuracy and convenience in prescribing medicine, easier check-ins, payments, checking of patients’ status, and tracking records by embedding NFC tags into the patient’s charts. NFC integrated devices can be easily paired and configured. Medical professionals can easily check schedules and access medical devices and equipment. The future of NFC in healthcare is very promising and many companies have already started investing. Diagnostic tags are under development to help monitor medical conditions such as temperature variations, blood glucose level fluctuations, etc.

5. Keyless Access

Keyless access is one of the familiar applications of Near Field Communication today. NFC’s convenience and ease of implementation makes it a popular choice for opening sealed doors. NFC and RFID tags can be used for accessing doors and restricted areas with an auto detect feature. It can be used to replace access keys, identification badges, and for easier access to cars and other vehicles.

Future applications of Near Field Communication

1. Smart Homes

Using NFC and RFID technology, we’ll be able to customize and program a particular application using our smartphones. By just activating an NFC tag, we can control our household equipment, launch apps, open, close, lock, and unlock doors, set alarm functions, or any other similar tasks using just our smartphones.

2. Logistics And Shipping

NFC and RFID tags can be conveniently used in the logistics and shipping industry.  Tracking and scanning of goods using smart tags make the system smart, errorless, and efficient.

3. Internet Of Things And 5G

IoT and 5G opens window of opportunities for new technologies to emerge. NFC enabled devices will be required in IoT and 5G enabled networks for easier implementation and efficiency (note: some people have expressed their concerns of 5G on health).

NFC Attack Methods

Although the communication range of NFC is largely believed to be limited to a few centimeters, the standard does not ensure security and safety of their private information.

Eavesdropping

Eavesdropping happens when a criminal “listens” in on NFC transactions. This should be preventable through the range of NFC itself since the device must be fairly close to send a signal. This should make it difficult for criminals to intercept the signal. Secure channels are also established; the information is said to be encrypted and decoded only by an authorized person.

Data Corruption And Manipulation

Criminals can manipulate and corrupt data, thus rendering it useless. Secure channels help prevent such manipulations. Some NFC devices have the ability to listen to impending corruption attacks and initiate prevention measures. Other NFC attack methods include interception, data modification, theft, and relay attacks.

Other Potentially Negative Uses – Implanting

Although implanting this technology into a person or animal for tracking, medical records, payments, access, etc. is being pushed and encouraged in some locations, this is a very frightening or worrisome development for many. For one, it’s extremely intrusive and unnatural. For two, there is both political and religious belief that this technology could be enforced or enticed onto the majority of the populace by the government, resulting in an end to personal privacy, the potential complete control of one’s actions or abilities to perform necessary tasks and functions, and even negative eternal consequences. So ya, implanting may not be such a great idea.

Conclusion

NFC technology will play an inevitable role in future smart devices for more integrated functions, such as: smart transportation, aviation, shipping, manufacturing, and automation of specific tasks. Integrating NFC technology with our modern data communication and transaction processes can ensure convenience, time saving, energy efficiency, and most importantly… improved security.
