VLC-based research achieved high-speed wireless access and decimeter-level indoor localization with complex equipment. However, it is still unclear whether the VLC is applicable for widely-used battery-free Internet-of-Things nodes, e.g., passive RFIDs. This paper proposes LightSign, the first cross-technology system that enables passive RFID tags to receive visible light messages. LightSign is compatible with commercial protocols, transparent to routine RFID communications, and invisible to human eyes. We propose a pseudo-timing instruction to achieve microsecond-level light switching to modulate the VLC message. To make it perceptible to passive RFIDs, we design an augmented RFID tag and prove its effectiveness theoretically and experimentally. With only one reply from an augmented tag, LightSign can decode 100-bit-long VLC messages. We evaluate LightSign in real industry environments and test its performance with two use cases. The results show that LightSign achieves up to 99.2% decoding accuracy in varying scenarios.<\/jats:p>","DOI":"10.1145\/3610883","type":"journal-article","created":{"date-parts":[[2023,9,27]],"date-time":"2023-09-27T15:45:03Z","timestamp":1695829503000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Cross-technology Communication between Visible Light and Battery-free RFIDs"],"prefix":"10.1145","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9058-8543","authenticated-orcid":false,"given":"Ge","family":"Wang","sequence":"first","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3726-6680","authenticated-orcid":false,"given":"Lubing","family":"Han","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8553-3902","authenticated-orcid":false,"given":"Yuance","family":"Chang","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4665-4834","authenticated-orcid":false,"given":"Yuting","family":"Shi","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6882-9590","authenticated-orcid":false,"given":"Chen","family":"Qian","sequence":"additional","affiliation":[{"name":"University of California, Santa Cruz, Santa Cruz, United States"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4317-5535","authenticated-orcid":false,"given":"Cong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5274-7988","authenticated-orcid":false,"given":"Han","family":"Ding","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9348-2982","authenticated-orcid":false,"given":"Wei","family":"Xi","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4603-4914","authenticated-orcid":false,"given":"Cui","family":"Zhao","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1037-9619","authenticated-orcid":false,"given":"Jizhong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Xi'an Jiaotong University, Xi'an, China"}]}],"member":"320","published-online":{"date-parts":[[2023,9,27]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/3241539.3241569"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1859995.1860008"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2016.07.004"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/3372224.3419211"},{"key":"e_1_2_1_5_1","volume-title":"RF-Dial: Rigid motion tracking and touch gesture detection for interaction via RFID tags","author":"Bu Yanling","year":"2020","unstructured":"Yanling Bu, Lei Xie, Yinyin Gong, Chuyu Wang, Lei Yang, Jia Liu, and Sanglu Lu. 2020.
