In the rapidly growing digital economy, where the consumers often face challenges in ascertaining the credibility of products, services, or the marketplace itself, the directive provides a necessary safeguard.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/evidency.io\/en\/timestamping-promotional-prices-omnibus-regulation\/\">Omnibus Directive<\/a> tackles three primary commercial practices that potentially compromise consumer rights, but today we are focusing in on the last of these: proving price compliance. Aimed at <strong>enhancing transparency in pricing<\/strong>, the directive forbids false promotions. <strong>Sellers must indicate the product\u2019s price before applying a discount, which must correspond to the lowest price charged during the preceding 30 days. <\/strong>Continuous violation of this provision can result in a two-year imprisonment and a fine of \u20ac300,000.<\/p>\n\n\n\n<p>These rules usher in a new era of consumer protection, where the onus is on businesses to maintain transparency and authenticity in their operations. Non-compliance isn\u2019t just risky; it can potentially disrupt businesses and their reputation in the market.<\/p>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\" id=\"titre2\">Timestamping: an effective solution for price compliance<\/h2>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<p>In this context, timestamping emerges as an efficient tool to prove price compliance. It involves <strong>recording the date and time of an event in a secure manner, providing an unalterable record<\/strong>.<\/p>\n\n\n\n<p>For e-commerce businesses, applying timestamping to price changes can ensure adherence to the Omnibus Directive\u2019s stricter rules on misleading promotions. The directive stipulates that the seller must indicate the product\u2019s price before applying a discount. This previous price should correspond to the <strong>lowest price charged by the seller during the 30 days preceding the discount<\/strong>.<\/p>\n\n\n\n<p>With <a href=\"https:\/\/evidency.io\/en\/qualified-timestamping\/\">timestamping<\/a>, businesses can <strong>easily verify and demonstrate that the discounted price and the original price adhered to this rule<\/strong>. Timestamping can effectively prove that the original price was indeed the lowest price charged in the previous 30 days, thus <strong>preventing deceptive promotional practices<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-3e83296906c66dbacf217c2f5c8c90a2\" id=\"titre3\" style=\"color:#0c0171\">Understanding the mechanism of proving price compliance<\/h2>\n\n\n\n<p class=\"has-text-color has-link-color wp-elements-798abf2ab644d17a748d631deaea3758\" style=\"color:#0c0171\">Timestamping, as a technology, leverages the principles of <a href=\"https:\/\/evidency.io\/en\/what-is-a-timestamping-token-technical-explanation\/\">cryptography <\/a>to provide a secure and accurate record of time for a specific event or transaction. Here\u2019s a more detailed look at how it functions:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hash function<\/h3>\n\n\n\n<p>When an event occurs, like a price change in an online marketplace, the details of that event are put through a <strong>cryptographic hash function<\/strong>. This hash function takes an input (or \u2018message\u2019) and returns a <strong>fixed-size string of bytes<\/strong>, typically a hash \u2018digest\u2019 that is unique to each unique input. It\u2019s virtually <strong>impossible to reverse-engineer the original input from the hash digest<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Timestamp Authority (TSA)<\/h3>\n\n\n\n<p>This hash digest is then sent to a trusted third-party entity called a <strong>Timestamp Authority (TSA)<\/strong>. The TSA generates a timestamp that <strong>includes the current date and time<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Digital signature<\/h3>\n\n\n\n<p>The TSA combines the hash digest with the timestamp and then uses its <strong>private key to sign this data, creating a digital signature<\/strong>. This signature confirms the TSA\u2019s endorsement of the timestamp.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Return to originator<\/h3>\n\n\n\n<p>The digital signature, which now contains the original hash digest and timestamp, is returned to the originator and can be <strong>stored as proof of the even<\/strong>t.<\/p>\n\n\n\n<p>The digital <a href=\"https:\/\/evidency.io\/en\/what-is-electronic-timestamping-and-how-does-it-work\/\">timestamp <\/a>proves that certain data (in this case, the price change) existed at a particular point in time. In the context of the Omnibus Directive, this timestamped record can <strong>prove that a price was changed at a specific time<\/strong>, thus ensuring that any price reductions meet the required 30-day lowest price rule.<\/p>\n\n\n\n<p>The critical point is that the data linked to the timestamp cannot be altered; any changes to the data would produce a different hash digest. Therefore, the use of timestamping provides a <strong>highly secure, tamper-proof method of recording the time of an event or transaction<\/strong>. Its applications in e-commerce platforms ensure <strong>transparent operations, trustworthiness, and enhanced consumer protection<\/strong>.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-772fafdb6c8c854a07a172b5384bafeb\" id=\"titre4\" style=\"color:#0c0171\">Penalties &amp; enforcement of the Omnibus Directive<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Sanctions foreseen by the Omnibus Directive<\/h3>\n\n\n\n<p>The law provides for heavy fines and even prison sentences in the event of a breach of these rules, ensuring strict enforcement. The maximum fine for abusive clauses is now <strong>\u20ac15,000 for individuals and \u20ac75,000 for businesses<\/strong>. In cases of large-scale infringement, the fine can reach up to <strong>4% of the company\u2019s average annual turnover<\/strong>, calculated over the last three known financial years.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Enforcement of the Omnibus Directive: record fines<\/h3>\n\n\n\n<p>In France, in July 2025, the Direction g\u00e9n\u00e9rale de la Concurrence, de la Consommation et de la R\u00e9pression des fraudes (DGCCRF, French equivalent of Competition and Markets Authority (CMA)) imposed a record fine of <strong>\u20ac40 million on Shein<\/strong> for <strong>misleading commercial practices, including fake discounts through prior price inflation and false environmental claims<\/strong>.<\/p>\n\n\n\n<p>At the same time in Spain, the Ministerio de Derechos Sociales, Consumo y Agenda 2030 fined <strong>seven e-commerce companies<\/strong> for simulating promotions during Black Friday 2023 by <strong>raising prices before applying discounts<\/strong>, with total fines amounting to nearly <strong>\u20ac350,000<\/strong>.[2]<\/p>\n\n\n\n<p>These actions clearly illustrate the strengthened enforcement of the Omnibus Directive, which demands full transparency on \u201cdiscounts\u201d, and show that European authorities are no longer turning a blind eye to such practices.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"has-text-color has-link-color wp-elements-4b97c91eb747206c3998daef3364b62b\" style=\"color:#0c0171\"><strong>Conclusion<\/strong><\/p>\n\n\n\n<p>Compliance with the Omnibus Directive is essential for businesses seeking to <strong>protect their reputation and maintain customer trust<\/strong>. Through timestamping, companies can demonstrate their commitment to <strong>transparent commercial practices<\/strong>, thereby enhancing consumer protection.<\/p>\n\n\n\n<p>Today, <strong>integrity and transparency<\/strong> have become non-negotiable requirements in the digital economy. By adopting innovative solutions such as timestamping, businesses gain <strong>concrete evidence of their compliance with regulatory obligations<\/strong>, strengthening their credibility in the marketplace.<\/p>\n\n\n\n<p>In the context of the Omnibus Directive, timestamping is more than just a technical tool: it is a <strong>practical response to the challenges of compliance and price transparency <\/strong>in the digital era.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-50\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/evidency.io\/en\/contact-evidency\/\" style=\"background-color:#0c0171\">Need to know more about timestamping?<\/a><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>References <\/strong><\/p>\n\n\n\n<p>[1] https:\/\/www.economie.gouv.fr\/dgccrf\/laction-de-la-dgccrf\/les-sanctions\/fast-fashion-lenseigne-shein-sanctionnee-pour-une#:~:text=La%20soci%C3%A9t%C3%A9%20Infinite%20Styles%20Ecommerce%20Limited%20a%20%C3%A9t%C3%A9%20sanctionn%C3%A9e%20d,d\u2019information%20sur%20732%20produits.<\/p>\n\n\n\n<p>[2] https:\/\/www.dsca.gob.es\/es\/comunicacion\/notas-prensa\/consumo-sanciona-siete-empresas-falsas-rebajas-durante-black-friday<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Disclaimer<\/strong><\/p>\n\n\n\n<p>The opinions, presentations, figures and estimates set forth on the website including in the blog are for informational purposes only and should not be construed as legal advice.
