The construction-led upgrade uses a CNC-anodized aluminium frame and fiberglass layers in a 2.2 mm card. Qi charging renews the sealed battery without a proprietary cable.
$40 typical
This is the one premium allowance because its materials and manufacturing are specific: CNC aluminium, fiberglass structural layers, a 220 mAh rechargeable cell and Qi charging in a 2.2 mm card. It is not ranked up for recognition or styling alone.
Adds edge rigidity and a noticeably more durable feel in a 2.2 mm card.
Resists flexing in a wallet while allowing the required antenna geometry.
Renews without opening the enclosure or a special cable.
A refined, extremely thin card with an aluminium perimeter that feels like a designed everyday-carry object rather than a promotional card. Qi charging is materially better ergonomically than a proprietary lead.
Recharge on a normal Qi pad; the claimed 12-month interval and metal/fiberglass construction should age well, but the internal battery is not replaceable.
