    EFT Syetms and Device Considerations

    EFT devices and systems differ depending on hardware vendor, country and bank / payment aggregator.
    Below is a list of things you may like to consider. This list is off the top of my head so it is probably not complete.

    Looking at the products and relationships us usually a good start.

    Things to consider:

    • Card skimming methods
    • Some EFT POS devices restrict the connection of a skimmer
    • Review levels of associated fraud
    • Review devices and EFT methods
    • Review terminal identification (merchant and customer)
    • Manual processing. (internal and external)
    • eCommerce products
    • PC based software
    • Dedicated server services (Nobil, etc.)
    • Web based engine (Custom objects, Web pop-ups, etc)
    • Authorisation / identification methods (Merchant and customer)
    • TCPIP session hijacking / session spoofing
    • Direct Debit as well as Credit Cards.
    • Swift (methods and controls)
    • Telegraphic transfer (methods and controls)
    • Payment aggregator relationships (eg. Payment Tech, manual processing, cheque scanning, etc.)
    • Internet banking facilities (attack / penetration,  Certificate registration / management, ISP SLA’s, etc.)
    • Implementation of Smart Card and / or alternative customer recognition devices.
    • Outsourcing and associated risks / service level agreements
    • Payment processing
    • Payment clearance
    • Payment switching
    • Reporting (segregation of merchant / customers / aggregators / partners / local / international)
    • Fraud detection and reporting
    • 3rd party acquiring risks
    • Single merchant ID many businesses
    • Allows moneys to be laundered if the payment aggregator does not place appropriate controls on the merchant.
    • Encryption used
    • Internet / trusted partner / inter-bank / extranet
    • Private and / or public certificates
    • Single use certificates
    • Client side certificates
    • Remittance advice processes and controls.
    • EFT disaster recovery and manual fall back procedures (associated security and reconciliation risks)
    • Trusted partner relationships, SLA’s, liabilities and risks.
    • EFT regulatory / legal requirements (inter-bank and government)
    • Refund processing / authorisation. (policies, procedures, controls, etc.)
    • CVV, CVV-2 / CVC-2 processing and management. (
    • Fraud detection mechanism (neural networks, inter-bank / department customer checks, etc)
    • Supported card schemes (AMEX/Visa/Mastercard/Discover/etc )
    • Review EFT floor limits (corporate and SME merchants)
    • Review the ability to withhold merchant settlement until the presence of fraud has been determined.
    • Review customer identification details. Such as (This varies around the world depending on local regulations / privacy laws)
    • Review real-time and batched processing methods and controls (sequence numbers, access to raw data, etc.)
    • Review processing with and without expiry dates. (exception controls and policies)
    • Review exception / fraud reports.
    • Review payment store and forward policies and procedures.
    • Review Pre-Auth and Completion controls.
    • Token based payment (eCash, etc)
    • Merchant reconciliation, reporting methods and controls (paper, Internet, email, PDF, Fax, etc.) and associated security.
    • Real time gross settlement policies, procedures and controls. (IT and amounts)
    • Card issuing policies and procedures. (customer ID checks, etc)
    • Banking infrastructure (ingress / egress) controls and security. (Web, partner, payment switches, outsourced infrastructure, monitoring / reporting.)
    • Use of Internet technologies for inter-bank transfers and remote equipment.
    • Physical security and controls of devices, ATM,s, line encryptors, etc.

    ISO 14443 contactless card

    An international standard for proximity or contactless smart card communication

    ISO 14443 contactless card

    ISO 14443 is an international standard which describes how contactless cards and terminals should work to ensure industry-wide compatibility, for example in identity, security, payment, mass-transit and access control applications.

    ISO standards are developed by the ISO, the International Organization for Standardization. Technical committees comprising experts from the industrial, technical and business sectors develop the standards to increase levels of quality, reliability and interoperability on a global scale.

    Gemplus has always had a strong involvement in ISO definition of the chip card standards, and has been represented in the development of this international standard. The ISO 14443 is divided into 4 separate parts outlining physical characteristics, radio frequency power and signal interface, initialization and anti-collision and transmission protocol.

    Gemplus has developed a wide range of contactless payment solutions based on the ISO 14443 international standard. The speed and convenience of contactless technology has created a significant demand for this sort of solution in environments such as fast food restaurants, gas stations, public transport services, banks and many others.

    What do you mean by three technologies on one card?

    There is confusing terminology used in the market to refer to cards that can support a combination of technologies. Cards are described as multiple technology when multiple, independent technologies share a common plastic card and do not communicate or interact with each other (e.g., magnetic stripe and contactless or contact chip). Cards are described as having a “dual-interface” when the card has a single integrated circuit (IC) that can communicate with a smart card reader/terminal via either contact or contactless.
