Its purpose is not entertainment or web browsing, but to <strong>support reception desks and customer-facing workflows<\/strong> where contracts, consent forms or other documents are signed.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Key differences when signing on a tablet<\/strong>:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Finger on the screen<\/strong>: generates only an image (raster). Fast, but less accurate and with lower evidential value depending on the context.<br\/><\/li>\n\n\n\n<li><strong>Generic stylus on an iPad or Android tablet<\/strong>: improves the user experience, but typically captures only an image without pressure or timing metrics and relies entirely on the app being used.<br\/><\/li>\n\n\n\n<li><strong>Professional digital signature tablet<\/strong>: captures both the signature stroke and <strong>signature biometrics<\/strong> (X-Y coordinates, pressure, timing, etc.), designed for intensive use and equipped to integrate with document management software.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><strong>Comparison table (device type vs. recommended use)<\/strong><\/h3>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>Device type<\/strong><\/th><th><strong>Captured data<\/strong><\/th><th><strong>Recommended use<\/strong><\/th><th><strong>Notes<\/strong><\/th><\/tr><\/thead><tbody><tr><td>Finger on a tablet\/smartphone<\/td><td>Simple image<\/td><td>Low-assurance signatures<\/td><td>Basic user experience; suitability depends on the legal requirements of the process.<\/td><\/tr><tr><td>Generic stylus (iPad\/Android)<\/td><td>Image (sometimes speed)<\/td><td>Internal processes, quick approvals<\/td><td>Limited legal validity unless it is linked to supporting evidence and the document.<\/td><\/tr><tr><td><strong>Digital signature tablet<\/strong><\/td><td><strong>Coordinates + pressure + timing (biometrics)<\/strong><\/td><td><strong>Contracts, consent forms, banking, retail, public sector<\/strong><\/td><td>Better technical evidence and traceability; integrates with DMS, ERP and electronic signature solutions.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>How does digital signature capture work?<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">When the signer writes their signature using the stylus, the device records the <strong>X-Y coordinates of the signature stroke<\/strong>, the <strong>pressure applied<\/strong>, and <strong>timestamps<\/strong> (speed and rhythm), creating the <strong>signature biometrics<\/strong>. On modern signature pads, this may also include a sequence number and a date\/time stamp.<\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Image vs. biometric data<\/strong>:<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>The <strong>image<\/strong> is the visual representation of the handwritten signature.<br\/><\/li>\n\n\n\n<li><strong>Biometric data<\/strong> describes how that signature was created (its signing dynamics).

A biometric signature captured on a signature tablet can generally support <strong>SES or AES<\/strong>, provided the system identifies the signer and uniquely links the signature to the document. A <strong>QES<\/strong>, however, requires a qualified certificate and a <strong>qualified signature creation device<\/strong>, requirements that go beyond the signature capture hardware itself. Its evidential value will depend on the <strong>overall body of evidence<\/strong> and the signing process.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>How to sign on a tablet: step by step<\/strong><\/h2>\n\n<h3 class=\"wp-block-heading\"><strong>Signing on standard tablets (Android \/ iPad)<\/strong><\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Open your chosen signing app and load the PDF.<\/li>\n\n\n\n<li>Sign using your finger or a capacitive stylus.<\/li>\n\n\n\n<li>Save and share the document.<\/li>\n<\/ul>\n\n<ol class=\"wp-block-list\"><\/ol>\n\n<p class=\"wp-block-paragraph\"><strong>Typical limitations<\/strong>: stroke accuracy, writing feel, latency, <strong>limited biometric data capture<\/strong>, and complete reliance on the app for <strong>traceability and legal validity<\/strong> (robust signer identification, timestamping and supporting evidence).
