China Unveils Offline SIM Card Wallet for Digital Yuan PaymentsThe People’s Bank of China (PBoC) has announced a new offline SIM card-based solution for its digital yuan, enabling users to make payments even with their phones switched off.Photo by Sumeet Singh on UnsplashEmbedded hardwareThe innovative initiative was revealed via a social media post on Monday. It aims to reach users with 2G phones who were previously unable to access digital currency.Currently, this feature is only available for Android phone users with NFC functionality, as no details have been given for iOS users or 2G phone owners. This innovation is part of the central bank’s efforts to expand the reach and usage of its digital currency, especially for users with 2G phones who were previously unable to access it.Earlier this year, the PBoC launched a similar solution for smartphone users, using near-field communication (NFC) technology. However, the latest solution relies on hardware embedded in SIM cards, which can act as a “hard” (offline) central bank digital currency (CBDC) wallet.Partnership with telecoms giantsThe central bank’s partners relative to this particular project include major telecom operators China Mobile, China Telecom, and China Unicom, as well as state-owned commercial banks Industrial and Commercial Bank of China and Bank of China, who have also introduced SIM card-based “hard wallet products.” These developments are expected to significantly improve the payment capabilities and network-free functionality of the digital yuan.To use this feature, citizens have to get a “super SIM card” from their carriers. After they have replaced their existing SIM cards and opened the digital yuan app on their phones, they will see an option to “open a SIM card hard wallet.” This will enable them to make touch-based payments to merchants even when their devices are powered off or lack network connectivity.SIM-based wallets are likely to be particularly useful for those using 2G devices or smartphones without NFC capabilities. Considering that about 20% of Chinese mobile users still use 2G phones, it would make sense for the PBoC to continue working in this direction with future updates.Driving adoptionThe ultimate plan of the PBoC regarding SIM-based wallets is not clear yet. However, recent developments, such as the pilot project in Qingdao where CBDC payments were tested on the metro system without electricity or network, indicate a strong push toward increasing the accessibility and adoption of the digital yuan.Frankly, moves to bring about adoption of the e-CNY have been nothing short of relentless. These measures have varied from paying state employees in e-CNY in Changshu, collaborating with French bank BNP Paribas so that its corporate clients start to use the digital yuan and enabling e-CNY bus fare payments on public transport in Jinan.China’s Jiangsu Province has integrated the digital yuan into its education system, while the resort city of Sanya recently introduced e-CNY ATM machines so that foreign tourists have a means through which they can access the digital currency. These developments demonstrate a clear commitment by the Chinese authorities in advancing the rollout of its central bank digital currency.

Amber Group Targets Trust in Web3 Via Thoughtworks PartnershipSingapore-based Amber Group, a leading digital asset service provider in crypto-related infrastructure, products and trading, has announced a partnership with global technology consultancy Thoughtworks.© Pexels/Palu MalerbaAI-led product offeringThe strategic partnership has been formed between the two entities in an effort to develop innovative security solutions that can enhance transparency and trust in Web3. It’s envisaged that in meeting this objective, product development will rely heavily on artificial intelligence-based technology.In a press release on Wednesday, Amber Group’s Head of Web3 Security, Dr. Chiachih Wu, said that the partnership allows the firm to provide its clients with “even more comprehensive and cutting-edge security solutions, such as automated software testing and AI-powered vulnerability detection.”Leveraging software design and security expertiseSong Zhang, Global Service Lines Lead at Thoughtworks believes that in order to advance the development of a next-gen internet, Web3 has to use “sophisticated engineering practices and scientific methods to address crucial issues caused by decentralization.” Zhang cites issues such as compliance, privacy and security. He believes that through the collaboration both firms can contribute to leverage their respective software design and security expertise, and in that way, tackle these challenges.“By using new technology and tools, we aim to create applications and new standards that promote the construction of a healthy, transparent, open, inclusive and responsible Web3 ecosystem,” he stated.Strategic realignmentThis is not the first strategic departure Amber Group has taken recently. Earlier this month the Singapore-based firm was said to be mulling over the sale of its Japanese crypto lending subsidiary. It’s understood that the proposed move would help the company to streamline its operations and focus on its core markets.Launched in 2018 as a joint venture with Japanese financial services conglomerate SBI Group, the Amber Japan crypto lending business had failed to gain traction in a difficult Japanese market.The firm acts as a liquidity provider, miner and validator on over 70 digital asset exchanges, applications and networks. Earlier this year it took the decision to cut headcount, in the process reducing staffing at its Hong Kong office by 40. Last December the firm shuttered WhaleFin, its crypto exchange business.The collapse of crypto exchange FTX in November 2022 had a knock-on effect on some of the firm’s products and customers. 10% of its trading capital was held with FTX when the exchange collapsed. Additionally, a number of the firm’s products would have experienced significant drawdowns without the company taking action. In response, Amber raised $300 million in a Series C funding round to overcome that challenge.Those events are likely to have been key in terms of the company subsequently taking a strategic approach of focusing on core business operations and partnerships like this one that it has just announced with Thoughtworks. Undeterred by the challenges, the company still focuses on becoming a category leader in the industry.
