For simple control at office entrances, a compact-format proximity reader (LINE 40EVO) offers fast RFID badge reading. To secure a sensitive door requiring a PIN code, a keypad reader in compact or large format (LINE K40EVO or LINE K80EVO) provides robust dual authentication. If the goal is to display clear visual instructions at a high-traffic access point, LINE 80EVO MATRIX (with 25 LEDs) or LINE 80EVO TOUCH (with touchscreen) are the best fit.<\/p>\n      <\/details>\n      <details>\n        <summary>What&#8217;s the difference between the Line Evo and Line Evo Matrix versions?<\/summary>\n        <p>The difference lies in the reader&#8217;s light display. The Line Evo version features a vertical 6-LED guide, ideal for displaying clean, streamlined signals. The Line Evo Matrix version uses a 25-LED matrix capable of displaying pictograms and dynamic visual animations. Both reader ranges offer identical 13.56 MHz RFID reading, the same security level.<\/p>\n      <\/details>\n      <details>\n        <summary>Is it possible to unlock access with a smartphone instead of a badge?<\/summary>\n        <p>Yes. In addition to reading physical RFID badges, the readers natively include Bluetooth (BLE) and NFC chips. The Castel Virtual Card app lets users validate their passage directly from their phone, with no card or code needed. This dematerialized feature works alongside standard proximity-badge reading.\nYes. In addition to RFID reading of physical badges, the readers natively feature Bluetooth (BLE) and NFC chips.
