Rendell, 28, will be out for the whole season after suffering knee ligament damage which requires surgery.
Cards director and club chaplain Ian Nicholson set up a crowdfunding page on Tuesday for contributions towards Rendell's operation and rehabilitation.
Ex-players and fans of several other clubs were among those to donate money.
Rendell, who scored 24 league goals last season, was taken off on a stretcher during the first half of Saturday's 1-0 defeat at Tranmere Rovers after rupturing his anterior cruciate ligament.
Fans of the National League side raised £1,234 during a bucket collection before their league game against Bromley on Tuesday while Bournemouth midfielder Harry Arter and Crawley defender Joe McNerney were among the former Woking players to made donations.
"Wow! We have reached our initial target towards Scott's costs," Nicholson wrote in a statement online.
"It has been a heartwarming week; we started tentatively hoping to get £1,000 and this shows what a wonderful family football is.
"Football fans of all ages and many clubs, Premier League and international players, club directors, many Woking fans and Cards players past and present have contributed. Thank you everyone."
