Ekster makes thin wallets, often leather, with an RFID-blocking layer and an optional tracker card. The tracker is a Bluetooth tag so the wallet can ping a phone when you leave it behind. Solar charging on that card is a product feature, not a privacy feature.
A tracker is a radio you chose to add. It helps you find the wallet and it is also a device that talks to a phone ecosystem, with whatever account that tracker uses. RFID lining only affects contactless card reads at very short range. It does not stop a skimmer, a stolen card number from a website, or someone reading the embossed digits. You are buying a slim wallet that is harder to scan in a crowd. Price it as leather, not as a security budget.
Use it for daily cards if you like the shape. Leave the tracker out if you did not want another radio. ekster.com
Ekster’s tracker card is optional. If you do not want a Bluetooth beacon in the wallet, do not insert it. The RFID layer is the privacy-relevant part, and it only applies to close-range contactless reads. Leather and a thin profile are the rest of the purchase. A smart wallet that notifies an app has an account somewhere. Read which phone ecosystem that tracker uses before you call the object a privacy product.
