In a context of rapid demographic and technological change, digital skills are needed more than ever for citizens to actively participate in society, but the level of digital literacy among elderly is lagging. As many services move to the digital world, the digital divide is bound to widen unless appropriate measures are taken to address elderly’s fear of technology. Accordingly, this study proposed a new digital literacy education program for elderly and sought to find out what changes there were by focusing on the digital self-efficacy of elderly. As a result, it was confirmed that the coding education program applied in this study had a positive effect on increasing the digital self-efficacy of elderly, resulting in a statistically significant change. Improving digital self-efficacy has a positive impact on elderly’s life in retirement, such as reducing depression and increasing life satisfaction. We hope that related research will be actively conducted and that ‘digital inclusion’ will be achieved, where elderly use digital technology to create a quality life.
