Apacer MicroSD Memory Cards are designed specifically for MicroSD Card applications that prioritize small form factors and low power consumption. These data-storage memory cards are functionally compatible with SD memory cards but are smaller. A MicroSD Memory Card can be inserted into a passive SD Memory Card Adapter and operate as an SD Memory card. All technical drafts follow DIN ISO standard. The Apacer MicroSD cards meet SDA (SD Card Association) specifications and are ideal for applications such as cameras, smartphones, digital recorders, MP3 players, PDAs, and electronic toys. These microSD cards feature firmware that significantly reduces the Write Amplification Factor (WAF).
