JCB Co., Ltd. Japan’s only international payment brand (Head Office: Tokyo, Japan) and Keychain GK (Head Office: Singapore) implement offline payments using near-field communication (NFC), self-sovereign identity, and blockchain technology.

With the spread of 5G and the development of Internet of Things (IoT) devices, machine-to-machine payments will automatically execute contracts and make payments without human intervention, and possibly without network connectivity.
JCB and Keychain have developed the first payment infrastructure for machine-to-machine transactions that supports offline payments using NFC. Leveraging Keychain’s blockchain and self-sovereign identity technology, the system addresses challenges related to the risks of operating through network outages and distributed attacks.
The new infrastructure allows payments to be conditionally accepted by merchants, even in the event that both the payer and the merchant are disconnected from the network, a scenario known as double offline. Notably, the shoppers’ experience is as easy as swiping a smart watch at the store payment terminal with this system.
Under the collaboration with JCB, Keychain implemented the payment processing system using IoT devices, mobile phones, and smartwatches, and demonstrated the following:
1. Payments may be conditionally processed even during a double-offline scenario.
2. Payment processing consensus may be done over mixed networks simultaneously.
3. Upon network restoration, the offline transactions may be securely repatriated to online in batches.
The system uses NFC network protocol and leverages Keychain Core to support small IoT devices with, in principle, as little as 32 megabytes of memory.

The International Finance Corporation (IFC), a member of the World Bank Group, has published the report Digital Entrepreneurship and Innovation in Central America, a study on the digital ecosystem in the region, with a focus on Guatemala, El Salvador, Honduras, and Costa Rica. Prepared in collaboration with the Regional Center for the Promotion of Micro, Small and Medium Enterprises (CENPROMYPE), the document reveals the opportunities for digital transformation in Central America, the challenges it faces, and the potential of this digitalization to attract investment and generate jobs.
Presented at a panel sponsored by the Central American Institute of Business Administration (INCAE), the results of the study are encouraging: Central American companies are eager to go digital and see e-commerce, financial technology, and robotics as especially transformative for their companies in the next decade. The report also confirms that technology implementation is key for business: companies that implement technology in their operations have higher productivity and generate more profits.
To build a solid entrepreneurial ecosystem, the study points out that greater coordination and participation of the public and private sectors, having adequate regulations and facilitating access to financing for technology companies, micro, small and medium-sized enterprises (MSMEs), and women entrepreneurs are essential.
Companies want to go digital, even more so after the COVID-19 pandemic, but not all have the opportunity to do so because they do not have access to resources. It is important to work with the financial sector to mobilize innovative funds and tools to the private sector, and especially to small businesses, said Sanaa Abouzaid, IFC Regional Manager for Central America. We are confident that this report can help guide the path of the digital revolution in the region, she added.
David Cabrera, Executive Director of Cenpromype, indicated that it is necessary that we take advantage of the mechanisms that integration gives us to make visible and to strengthen institutional efforts, programs, and actions aimed at giving added value to the production of MSMEs, considering processes that allow the generation of new products or services, improvement of management or organizational processes, or improvements in marketing strategies”
This is confirmed by the report: bureaucracy, access to financing, lack of information about technologies, limited technological skills among the workforce, the lack of national and regional strategies that promote e-commerce, and the lack of a more agile and friendly regulatory framework, are some of the barriers that slow down the digital transformation in Central America. On the other hand, it highlights opportunities to enhance the digital ecosystem, such as promoting a digital transformation strategy and e-commerce, promoting greater participation of women in the technology sector, increasing collaboration between the public and private sectors, and promoting alliances between the supply and demand of technology.
For this study, surveys were conducted with more than 2,000 companies from a variety of key sectors in Central America, including the technology, education, agricultural and tourism sectors, and a multitude of small and medium-sized enterprises.
The panel presentation of the report, moderated by Camelia Ilie, Dean of Executive Education and Strategic Innovation of INCAE, was attended by senior representatives of the public and private sector, including the Minister of Economy, Industry and Commerce of Costa Rica, Victoria Hernandez; IFC Senior Vice President of Operations Stephanie von Friedeburg; IFC Central America Manager Sanaa Abouzaid; the Managing Partner of the Salvadoran investment fund, Innogen Capital, Fernando Morán.
