Seamless sharing of important files without email hassle
Asking customers to look for email attachments or download third-party apps creates friction and reduces conversion rates. With RCS, businesses can send structured documents—such as PDF invoices, contracts, tickets, voice messages, and contact cards (vCards)—directly within the chat conversation. Customers can preview, play, or save the files to their device with a single tap.
Three powerful file formats in RCS
Interaktiva PDF & Dokument
Interactive PDFs & Documents
Audio Files & Voice Messages
Send personalized voice messages, audio guides, or voice verification codes. The audio plays natively within the messaging app's player, with full volume control.
Digital Contact Cards (vCard / .vcf)
Make it incredibly easy for the customer to save your customer service or salesperson’s contact details. A vCard contains phone numbers, email, address, logo, and opening hours.
Combine with keyboard shortcuts
Include clickable actions next to the file. For example, a "Pay now" button next to a PDF invoice, or a "Call support" button next to a contact card.
Practical applications for your business
Finance & Invoicing
Send the monthly PDF invoice or statement with a verified sender stamp. This reduces the risk of missed payments and increases security.
Travel & Events
Deliver PDF tickets, itineraries, and a ready-made vCard to the hotel reception or your tour leader so that the customer has everything in one place for the trip.
Customer Service & Support
Allow customer service agents or AI bots to send step-by-step guides in PDF format or short audio instructions for complex technical troubleshooting.
Guaranteed delivery even with limited reception
Important documents must never go missing in transit. If the recipient's device lacks internet access or RCS support, the iP.1 platform automatically reroutes the delivery. The document or contact card is then delivered via a secure SMS containing an encrypted, one-time web link where the customer can download their files.
Frequently asked questions about documents, audio, and vCards in RCS
For documents, PDF is primarily supported, but common office formats such as DOCX, XLSX, and TXT are also supported. For audio files, standard formats like MP3, AAC, WAV, and M4A are supported, up to 10 MB per file.
When a vCard is sent via RCS, it appears as a sleek contact card in the chat. The customer simply taps the 'Save contact' button to add the phone number, email, address, and logo directly to their mobile's address book.

For privacy reasons and in accordance with mobile operating system standards, the customer is required to press the 'Play' button to start audio playback.
With RCS, you can send files up to 10 MB (some operating systems support even larger sizes). This compares to MMS, which has a strict 300 KB limit and rarely allows documents to be sent at all.
