China Unveils Offline SIM Card Wallet for Digital Yuan Payments
The 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.
Embedded hardware
The 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 giants
The 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 adoption
The 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.
