These locks required a physical metal key to open and were vulnerable to loss, duplication, and security breaches. The check-in process was manual, and re-keying a lock for new guests was time-consuming and expensive.<\/div>\n<ol class=\"list-number1\" start=\"2\">\n<li class=\"ace-line ace-line old-record-id-Gd4gdV3AzoCvyHx7164caGBxnhY\" data-list=\"number\">\n<h3><span class=\"ez-toc-section\" id=\"The_Invention_of_the_Key_Card\"><\/span><strong>The Invention of the Key Card<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ol>\n<div class=\"ace-line ace-line old-record-id-X9NtdlcE4oJF26xL8dEcYmbtnab\">When were key cards invented? The first keycard system was introduced in the 1970s. Norwegian inventor Tor S\u00f8rnes developed the first mechanical hole-punch keycard, inspired by punch cards used in computing. This key card could only be used once, and it replaced the physical key with a programmable punched card.<\/div>\n<div class=\"ace-line ace-line old-record-id-GlMmdS2HWobbQIxJjX3chlflnpg\">This technology quickly caught on with hotels seeking better control over room access and faster guest turnover.<\/div>\n<ol class=\"list-number1\" start=\"3\">\n<li class=\"ace-line ace-line old-record-id-I5badJFcpoZj1Nxac2RcDogrnWc\" data-list=\"number\">\n<h3><span class=\"ez-toc-section\" id=\"The_Rise_of_Magnetic_Key_Cards\"><\/span><strong>The Rise of Magnetic Key Cards<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ol>\n<div class=\"ace-line ace-line old-record-id-H2kDdOzRQouyv6xUM38cXtgJnNd\">By the 1980s and 1990s, magnetic key cards became the standard. These cards used magnetic stripes to store access data and were read by swiping through a hotel door lock card. This allowed hotels to issue a new door lock key card for every guest without replacing physical locks.<\/div>\n<div class=\"ace-line ace-line old-record-id-JDOmd7qhFoYp9IxE7c6cci7snWf\">However, these cards were vulnerable to:<\/div>\n<ul class=\"list-bullet1\">\n<li class=\"ace-line ace-line old-record-id-IQifdsssco6OAfxMMnAc08mNnTh\" data-list=\"bullet\">\n<div>Demagnetization<\/div>\n<\/li>\n<li class=\"ace-line ace-line old-record-id-HHssdfiQ6ovhroxIUjmcEbdln7e\" data-list=\"bullet\">\n<div>Physical wear<\/div>\n<\/li>\n<li class=\"ace-line ace-line old-record-id-DVBdd8sa8ouUZhxswbhcTtEgnQd\" data-list=\"bullet\">\n<div>Easy duplication or hacking attempts<\/div>\n<\/li>\n<\/ul>\n<div class=\"ace-line ace-line old-record-id-YLwsdgLGRo9oXtxMVEscSMnange\">Despite limitations, magnetic cards remain in use today, especially in motel key card systems and budget accommodations.<\/div>\n<ol class=\"list-number1\" start=\"4\">\n<li class=\"ace-line ace-line old-record-id-GuVTdSiroo9JlExPFuTcp67Pnjf\" data-list=\"number\">\n<h3><span class=\"ez-toc-section\" id=\"The_Advent_of_RFID_and_Smart_Cards\"><\/span><strong>The Advent of RFID and Smart Cards<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ol>\n<div class=\"ace-line ace-line old-record-id-X32KdEdoWo3XQDxbFmVcG0H2n5c\">In the early 2000s, RFID (Radio-Frequency Identification) technology transformed key card access.
